: [DIY] Install CTS-V Brembo Brakes on CTS (Part 1, GETTING STARTED)

PLEASE READ!
Now that I have completed the MOD there are things I would change if I could. First, I would have ALL the parts before starting (I did not). Second, I would do the install in “BLEED” order:

Right Rear
Left Rear
Right Front
Left Front

This way, when you’re done with the install, you bleed it and you’re done. So read all the parts here and then do the install in the order listed above.


After asking many questions concerning the possibility of putting 2009-2012 CTS-V Brembo brakes on the 2008-2012 CTS and getting answers from “it can’t be done” to “it may work” I decided to give it a try. I got my courage from the fact that JDP Motorsports sells a kit using the same parts. So here it is.
I had to break this up into three parts because the system will only allow 15 photos. I have way more then that.

Part 1, GETTING STARTED,
Part 2, DISASSEMBLY (FRONT)
Part 3, INSTALL NEW PARTS (FRONT)
Part 4, DISASSEMBLY & INSTALL NEW PARTS (REAR)
BLEEDING BRAKES AND BED IN THE NEW PADS


[DIY] Install CTS-V Brembo Brakes on CTS (Part 1, GETTING STARTED)

Disclaimer: This Mod is being performed on my 2008 CTS RWD w/FE2 option and 19” CTS-V wheels. I will not address the CTS 4 though I have found no reason to believe it will not work on any 2008 – 2012 CTS with 18” wheels. So, take some time to measure your wheels for clearance.
Here is a link to JDP Motorsport that may help.

The parts list:
Parts cost change almost daily so this is as close as I could get. I can say the pare numbers are the ones I used. As you can see, the rotors account for 1/3 of the total cost. There are hundreds of rotors available for the CTS-V. If the OEM Brembo rotors listed are not to your liking then any rotor made for the 2009 – 2012 CTS-V should work and save you $$$.

My calipers started life Yellow with V logos but thanks to the magic of VHT Red and Clear Caliper paint and some Brembo Logos they are now Red. The Yellow was beautiful but I didn’t want to use the V logo. The directions on the VHT can are not clear with respect to curing the paint. Here is what I did:

READ THE CAN! I got much of the following via phone with VHT.

1. Sand the flat area of the V logo with 1200 wet paper. If you are going back with same color then do not sand more then that area.

2. Sand or Red Scotch Brite Pad (VHT recommendation) the whole caliper, it comes with the input hole plugged with a blue stopper so it is waterproof.

3. Use hair dyer or let it set overnight.

4. Mask off the area not to be painted. In my case that was the bleeders, inlet hole, pistons and the area where the ends of the pads contact. I used Blue painters tape for masking, tested a sample in advance, and it had no problem throughout the process.

5. If keeping the Yellow, mask all but the flat surface where the V logo is. Go to the edge so if the paint does not match exactly it won't mater so mush. You can use printer paper for the large areas.

6. Paint, two light coats followed by one wet coat. Wait 10 min. after each coat.

7. As soon as it’s dry to the touch, 20 min, very carefully apply the logos. Pressed on the letters and try not to stick down the backing tape to much. Remove the backing tape and ensure the letters are flat.

8. If you are keeping Yellow remove all the masking. The clear will help cover the ledge created by the tape.

9. Apply two coats of VHT clear.

10. Number 6 thru 8 must be done within one hour.

11. Now, send your wife shopping while you hang them in the oven at 200 degrees for one hour.


It's paint. The worst that could happen is you get new logos and start over.

I got the stickers here:

beautiful write-up! so the "backing plates" are the same as the "splash guards"?

Mistercoffee2
06-19-13, 02:29 AM
I guess I did intermix those two terms. I think the term "backing plate" comes from the drum brake days when the shoes mounted on the "backing plate". I guess that applies to the back of the CTS because the parking brake shoes mount to the backing plate. No backing plate on the front so I will edit.

Thanks. This is a simple to install upgrade but the parts are still expensive. For most people the probably can't be justified. But there are those of us who love mods like this and I think you are one of them.

I apologize for the delay in doing the rear but I still have to get some of the parts (need money) and the Goodridge lines are still three weeks out. I'm hoping by the week of 8 July to complete everything. Best Guess.

Now is the time to start collecting the parts. Hopefully the sources I listed will keep things in stock. Goodridge is a real problem. They say a manufacture run of our lines will be done soon so get your order in to Wundercarparts.

[QUOTE=Jagillac;3562282]Thanks again Mastercoffee2,


Well just after replying to your post I decided to get some more of the rear parts ordered and Amazon now has a backorder on the RR caliper. If this holds up I can get it from JEGS for about $30 more. I still need the rotors and backing plates and for now they are in stock. (if only I had $500 in stock lol)

You know, I just spent a lot on my wife's birthday. Now I'm having second thoughts about that decision.

Nicely done. I am not sure if I will do this, but I have thought of it. Good write up. Any difference with just the fronts installed?

Mistercoffee2
06-24-13, 08:15 PM
UPDATE: Things are coming together. Got the Goodridge lines today and the rear calipers will be here tomorrow. The rear backing plates and rotors are also on the way.

I was looking at the price list and realized that more then 1/3rd of the cost is in rotors. I have always questioned my decision to go with the Brembo (OEM) 2 piece rotors on the front due to cost. So, sense the rear brakes are good for nothing but parking anyway, I have decided to cut cost I will go with Centric 125.62119 rotors on he rear. (Cost for OEM = $427.80, Centric = $164.88, savings = 262.92 shipped.

I will add these to the price list and you can choose.

I knew I would have to paint the hat on the OEM rotor black to match the front and the Centric is black.

EDIT: Decided to just put in a statement about rotor availability and cost.


I really hope to finish this by Christmas...just kidding. Next week.

I was doing some research on the part numbers for the rear backing plates for the CTS-V vs CTS and found that they are the same numbers on 2009 up. This is no doubt due to the introduction of the electronic parking brake in 2009. So it looks like you will not need to change them on 2009 up CTS. However, this does bring into question the ability retro these to the 2008. We shell see.

Where do you find the Hawk front brake pads for 106.52? The cheapest I found is 156.93 on amazon.

Where do you find the Hawk front brake pads for 106.52? The cheapest I found is 156.93 on amazon.

OK, you caught me. I had to go back and look at my Amazon order. If you shop Amazon much you know that if you look close you will often see something like "1 used from $68.96" and in my effort to get the lowers price I went there. Amazon does not sell used stuff, used to them is new item, scratched, in damaged box or maybe no box. Mine was a damaged box for $106.52. An example, at this moment the rear pads are $98.52 but can be had for $68.96 with cosmetic damage. Cosmetic damage on a brake pad? Good deal!

Now, I forgot and never should have used that price on my price list so I will correct it. That said, prices change and at the moment $168.48 in the lowest I see on Amazon. Free shipping. There are lower prices around but shipping cost brings the total above Amazon. The source and price I listed was the price I paid and the best I could find during the weeks I spent looking.

PS: the picture of Hawk Performance HB649Z.605 is not correct on amazon and that screwed me up for a long time.

I was just lucky that day (31 May 2013)

If someone is truly going to do this mod and keep Yellow but change to Brembo logos, I have a set of Black logos I will give you if you PM a place to mail. 1st come.

This does mean I will have to see pictures of your work to verify you used them.

I have that old KNOCK in the left rear over bumps so when I do the rear Bembo Brakes I will replace the knuckle. The right one was replaces a little a year ago.

It's not a mod but do you guys think I should do a photo sequence of the process and document it in another thread? Has anyone done this? I have not seen it anywhere. I will replace the entire knuckle as GM recommends, not the bushings only. When the dealer did the right side they listed a required 4 wheel alignment.

Parts cost $132.77 Shipped

I will have all the missing parts next Wednesday. Amazon split the order for the rear backing plates. One will arrive tomorrow and the other next wednesday.

Waiting has been hard. Every time I have to stop at a light I just know the guy next to me is saying:

"WTF is wrong with this guy. He put Brembos only on the front."

So I just keep hang my head in shame.

I noticed you removed the note about the rear backing plates only needed for the 2008 model. Does this mean every model year needs it?

Mistercoffee2
07-17-13, 11:39 AM
I was confused by the part number info.

Part number 15853380 fit 2008 > 2012 CTS, NO CTS-V. That would be the small one.

Part number 25851205 (on the parts list) fits 2009 > 2012 CTS and CTS-V. NO 2008. That would be the large one.

There is something wrong here. Why would they list the large backing plate for the CTS? The cutout in it is for the Brembo caliper.
So, bottom line is the large backing plate is required.

The brakes are unbelievable. Go test drive a V.

I'm not sure it will ever be done. Yesterday I had 295/35 Goodyear Eagle F1 tires mounted on the 10" Coupe wheels. Boy are they wide. Then, as a test, I put the the 285/35's from the rear on new 9.5x19 CTS-V wheels that will go on the front when the 11mm spacers arrive next week. If the size works out I will replace the tires with 285/35 Goodyear's. Then..., the 9x19's wheels off the front will go to Weldcraft Wheels Inc. and be widened to (10.5" or 11", not sure yet) and replace the 10" on the rear so they will FINALLY not stick out past the finder.

Done! Post photos.


Then the 10" CTS-V Coupe wheels will be sold.

More then you wanted to know, right?

OH! I forgot the spring kit and splitter. I may do my own splitter.

I have no parts info source for the ATS. I would think it very unlikely it shares many parts with the OLD (2008-2013) CTS. Maybe with the 2014 CTS.

We are doing a lot of the cts v brakes in the GTO community right now.
I did 6 piston front and 4 piston rear in silver. Mine were less than 2000.00 with most everything sourced from amazon except the rotors(centric) from tire rack.
Did you guys now that the 4 piston Camaro SS rear calipers are the same and can be substituted for only $55 each?

Thanks b4z and a warm welcome to our GTO friends.That would be great we all like saving money. We will need source and parts numbers for these parts and I will update the parts list.

Also, as I have said here, a large part of the cost in the MOD I did was in the 2 piece front rotors.

Looks like the same caliper as the Yellow CTS-V one I used. Yes, there is a left and right. I suppose if you flipped it and moved the crossover tube to the bottom end it would work on ether side. I'm not sure.

If anyone installs these calipers let me know so I can add to the parts list.

Amazon has a very liberal return policy. You face the same issues I did when I started. You will have to be the first. There are Brembo brakes for almost any car. The question I have is what diameter rotor are these calipers made for.

I put 2012 Chevrolet Camaro in the fitment box and they say it fits. You will also need the rotor.
Notes: Rear New Caliper, LEFT HAND - w/o BRK PADS & BRKT - SS - EXC SYNERGY SPECIAL EDITION PKG 2(AJB) - EXC SYNERGY SPECIAL EDITION PKG(AJA)

Maybe you could look at what the PKG 2(AJB) and (AJA) are on a Camaro.

If you read my MOD you know that I ordered one and tried it for fit.[COLOR="Silver"]

Keep in mind you can get this one:

As far as I know they offered Yellow, Silver, Red and maybe Black at the same time. I'm sure our resident user/dealer can clarify that. Red is the cherished and very expensive $$$ option.

That's why I got Yellow and painted them Red :yup: Not really. Although beautiful (so as not to alienate those who have them) black and yellow gives me a headache while black and red gives me a semi. (I'm sure I can't say boner here)

I would be very surprised if that is true. I did a lot of research and could not confirm it but I thought the pistons were different sizes in the colors. Tried searching through the part numbers for the piston kits but my hair started smoking so I gave up.

Porsche also uses color to designate their calipers with red being the top and only on the top models. The brake specs are the same. 996 C2's got black calipers and C4's got silver calipers. GT3 and Turbo got red calipers.

Cool! The Silver V calipers will work. The Chevrolet may as well but I don't know.

What will you do to the calipers. Surely not leave the "Chevrolet" on them. With the Silver ones you can let them be if you wish. Painting is a hassle but sometimes worth it..

I had problems with the VHT system. On both color and clear coat the directions say to apply two light coats followed by one medium wet coat, ten minutes between coats and all coats must be done within one hour. Else you must wait seven days.

So, you have to put on color coats, put on the stickers, then coats of clear, all within one hour, then bake at 200. The paint does dry to the touch very fast.

I had problems with the later coats, the clear, "crinkling" the paint already applied. When that happens you have to strip and start over.

I got it done but it was not fun. A call to VHT was not helpful.

On your parts list you have the rear rotors as 177-1105. When you search on that on amazon that's for the fronts. When I did a search on rockauto, the rears are 177-1051 http://www.amazon.com/ACDelco-177-10...words=177-1051

Did you put the 1-piece front on the rear?

Here is the part number I used and the one pictured in the MOD. I got them from AutoAnything but these are the same part number and cost less. I did paint the edge silver to closer match the front.
http://www.amazon.com/Centric-Parts-.../dp/B008CRLGJM

The numbers listed in the MOD are the OEM Brembo parts because thats what the MOD was about. However, I did note that there were a lot of other rotors that could be used.

Hello all. Time, and experience changes everything, including this MOD. My goal was to put the OEM CTS-V Brembo brakes on my CTS, and I did, with the exception of the rear rotor which in Centric, (the one on the parts list in OEM), lines and pads.

And now I cannot even edit the MOD for updates. :annoyed: :banghead:

Given what I have learned in the past 6 months, mostly through your comments, I should have broadened my view a little and also looked at the Camaro SS Brembo parts as well. They appear to be the same parts and less expensive although I cannot verify this. A little Yellow or Red paint to cover the "Chevrolet" and they should look the same as well. One of you will have to step up and try it. is250sp may be doing that as we speak.

If you shop for the best deal on calipers and rotors all the other parts on the list are golden.

----------

There is a part number error in the list (thank you is250sp). The number listed for the rear rotor is if fact the one piece front rotor. If you look on Amazon and many other sites the photo shown with this number is a rear rotor. Tonkin says it is the front and rear rotor.

I cannot edit the list and right now I'm not sure what the number is for the OEM CTS-V rotor so hopefully anyone looking at doing the MOD will read this thread.

Keep in mind you can get this one:

for a little more and it will fit the CTS and doesn't have "Chevrolet" on it.

When I did a search for 172-2308 on rockauto, it say this part is for the 04-07 CTS-V. How do you know it fits on an 09+ V?

Mistercoffee2
09-17-13, 06:07 PM
Yes, that is correct. I'm sorry. I searched 2010 CTS-V and it came up.

I worked for weeks to locate, purchase, test install and write up the install of Brembo brakes using Yellow rear calipers numbers 172-2523 and 172-2524. If you want to use others, order and test them, and let us know how it goes.

Edit: From my notes, RockAuto, front, one side.

Yellow ACDelco 172.2523, $272
Silver ACDelco 172-2486, $281
Red ACDekco 172-2580, $1023

I have been scouring your parts list and am looking to do this on my 2011 CTS Coupe. I know you haven't tried it on a CTS4, but any reason to believe this won't work?

Any assistance or guidance would be appreciated.

Thanks.

As far as I can tell from this forum only myself and Mistercoffee has performed this upgrade. I don't track my car so I can't say anything performance wise but so far I love it. My coupe was already lowered with aftermarket rims so I was already getting a lot of looks, but adding the Brembo's with drill-slotted rotors brings neckbreaking to a whole new level. If the CTS4 uses the same rotors and calipers as the RWD then it should fit.

CrashGuy2016
03-24-14, 07:07 PM
Thanks for the info. Re-read my post. Not sure why I added a "4" in there! That'd be my AWD Wagon, and I want to do this on the Coupe.

If you did a 2012 Coupe, it is also a 2nd Gen CTS. Mine is also RWD.

Can I ask whose rotors / source?

Thanks!

Slim taking the plunge.. Slowly...

I appreciate the input so far.

I've ordered one front caliper and one rotor for test fitting.

I've 18" snows on rims, but 19" stock rims.

The clearance on the 19's won't be a problem based on the 8" clearance (x2 or about 16 in on the inside of the plus about 1/2 for the larger fronts).

The 18's are a question mark.

Will update as I go.

You might need spacers and longer wheel studs to accommodate the OEM 19" wheels (depending on which style you have).
I test fit the V calipers on my OEM 19" wheels and they come in contact with the wheel before it is fully seated on the hub.
I purchased a set of 11mm spacers but have yet to test fit them on the car (gonna wait till the warm weather hits).
I have an AWD car so it may be different on the RWD models.

If the warmer weather holds over the next few days / weekend I will get a test fit. I picked up a set of 5mm spacers on a wing and a prayer to see of a) I need them on the RWD, and b) if it is enough.

I also measure the inner circumference on my 18" winter rims, and have about 17.9" of clearance. The picture on JD Motorsports show 16" for the rear. Since the rotors for the front are .2" larger, I figured I needed > 16.4" plus some wiggle room.

Have more than wiggle room.....

So far both parts lists - the one posted, and one sent, have been right on....

CrashGuy2016
04-18-14, 04:37 PM
UPDATE - It was a bit warmer......

So I test-fit the front. For the stock 19" rims I will need 10mm spacers. I grabbed some 5mm off eBay for the test fit. Double them up for a 10mm space yields a comfortable margin.

Given this only gives 3.5 turns of the wheel nuts to snug, I will want more bite.

Anyone have a good source / spec for 10mm longer studs? I SHOULD be able to press in / Press out or brass bar hammer them out. I may opt for replacement wheel bearings and change the studs on those and swap them in when I change the backing plates.

Using 10mm spacers I will loose the hub-pilot / centering though. I had this on my snows in the first place. I was wondering about some kind of centering piece that goes INSIDE the end of the bearing hub?

Any thoughts or suggestions welcome!

Great write up!
From what I see, this is a direct bolt-in upgrade. The challenge is in rounding up the parts.

I have two questions:
1) What is the center to center measurement between the two mounting holes on the CTS-V calipers?
2) Why would you not use aftermarket rotors that are cross-drilled and slotted (And, around $100/pr?)

CrashGuy2016
04-26-14, 08:36 AM
The calipers bolt on in place of the caliper bracket for the non-fixed calipers. No drilling or other mods.

The backing plate needs to be changed as the V rotors a bit bigger than even the HD brakes my Coupe has.

Unlike the others, I'm keeping my stock 19" rims (and 18" snow tire rims).

The only hurdle I'm overcoming is the Brembo caliper is thicker due to its "fixed" nature.

Without wheel spacers you can't do it. The stock rims won't clear the caliper.

I've got new, 10mm longer studs pressed into the new hubs. Also have 12mm spacers coming.

I had a local machine shop make "hub extenders" that pressed into the end of the hub (not doable on an AWD with the ones I had made) to keep the hub centric fit. While they make these for BMW I never found them for Cadillac.

All the parts were easy to find on amazon and GM parts direct.

I did not go for cross drilled vented on them at this time.

Can you elaborate on your "hub extenders" or do you have a picture?
Are the spacers you're using flat? Or do they have the hub-centric lip incorporated?
I purchased the Weapon X 11mm spacers (haven't installed them yet). But I was under the impression that no other hardware would be necessary to mount and clearance everything.

****UPDATE *****

If you are considering this, JUST DO IT! I miss my Camaro SS a little bit less today....... I have completed the front change over to the Brembo 6-piston fixed caliper ala CTS-V.

The stopping power difference is VERY noticeable. I will be doing the rears in a few weeks.

I have the 19" Performance package wheels on my RWD 2011 CTS Coupe. I also have 18" Winter rims with snows. I have retained the stock wheels and the snows fit around the calipers no problem using 12mm spacers.

I will add a few things to the parts list as previously posted here:

Dorman 610428 wheel studs. These are about 10mm longer than stock. I bought them at http://www.thewrenchmonkey.ca for < $25 including tax and shipping. Beware, some websites will want to gouge you $4-$5 for each stud!

Motorsports Tech wheel spacers. http://www.motorsport-tech.com/wheel_spacers.html - I ordered 2 x 12mm, hub-centric, and my order reads:

2 Spacer - Hub & Wheel Centric 5x120 66.95 to 66.95, 12mm Thick 45.00ea

These allow me to retain the hub-centric fit of the stock 19" rims. I didn't need the hub extenders I had machined after all, since going 12mm allows for enough material past the end of the hub for the machinist to make a new flange.

I went with the Centric performance rotors (NOT cross-drilled or slotted). I used the Hawk ceramic pads as well.

The other thing I opted for was two new hubs. PartSource here had a 30% off sale on all Moog parts. They were about $200ea. It was easier to install the new studs on a press vs. me hammering them out and hammering in or pulling in with wheel nuts etc......

I figured since I need to pull the hubs off to change the backing plates (and studs) I would just replace them even though mine only have 45,000 km on them. This area of the car always gets a lot of corrosion in them and "glues" the hubs in. Whenever I have changed hubs on any vehicle I have had, I put a light coating of anti seize in the hole, then wipe to make sure it is a thin coat, then torque to spec.

I would also recommend having one or two rotor bolts on hand. The torn heads on these like to strip and it makes for an easier assembly of the wheel and spacer and rotor and pads if you have the rotor secured.

You will likely have to do some adjustment of the brake lines out of the box i.e. how much is on either side of the hold-down clamp. Also, the brake line adapters in the separate parts bag are needed for the front hoses.

All in all an easy install. The longest part was banging out the old hubs!!!

I will update once the rears are done. From the measurements I did I don't think I will need spacers, and if I do, likely no more than the 5mm I have on hand. The "fun" part will once again be hammering out the bearings! If anyone has an easy way, let me know!

Pics??? Also I don't know the offset for the stock 19's but my guess is if you did 12mm spacers for the front and 5mm rear it may look funny with the fronts sticking out more than the rears.

CrashGuy2016
05-05-14, 05:57 PM
I will take a few and post them. Looking at the car, you really don't even notice the 12mm offset on the front. If I go 5 on the rear, that leave 7mm. I'm not so sure that fine a difference is noticeable without a tape measure.

I am considering two more hubs and a set of studs though, just in case.... let's see how the budget holds out!
