Hey, i'm new to the forum. i run an automotive shop, and have done thousands of brake jobs over the years, last week i did a resurface and installed new pads that i had in stock, the brakes really started squealing bad, i took everything apart re lubed everything, and put it all back together, still got bad squeals, so i ordered some new ebc cross drilled rotors, thought maybe i'd turn the factory rotors to much, after replacing the new rotors, and installed new pads i still got the squeak, has anyone else ran across this problem. Thanks john
Here is a URL for Pad most prople are using http://www.cadillacforums.com/forums...-pad-sale.html
This one was on parge 4 of the forum There are mentions of brake pads on pages 2,3, and so on. Take a look
The guy at this url can do you right with prices and services. I buy from him all the time.
When I bought mine the dealer put those on because they had to put pads on to certify it and they did not have the GM pads in stock. I made them take them off because the squealing. The stock pads do not squeal. I have since put on Hawk Ceramic pads and have no squeal and much less dust than the stock pads.
While I have not done brakes on this car yet (since it has newer ones on it), my two suggestions;
1) How much Ni-Glue (GM's name for it) did you use on the backing plates on each pad. CRC makes a suitable alternative called Disc Brake Anti-squeel and is orange. It spreads on like liquid, but then hardens to a sticky rubber texture and helps alleviate squeeling from the pads vibrating up against the pistons/caliper where they mount to.
2) If there are any little steel metal clips that, usually attached to the caliper bracket, which the pads ride in. These pieces can also serve to help keep pads from vibrating from rotational forces as you brake. Chrysler vehicles specifically are pretty notorious in adamantly using these metal pieces as anti-squeel devices.
I have Hawk pads on both my GTO and on my previous Bonneville GXP. They both squeeled. The GTO no matter how much I try to quiet them down, are still embarrassingly loud to drive around in traffic even after getting them hot. They still squeel so bad. Before you tell me I don't know what I'm doing, much like the OP owning his own shop, I'm a former GM technician and have done my fair share of brake jobs over the years! Anyway, I've had them off 4x to try to stop them from squeeling and I'm ready to chuck the expensive PowerSlot rotors to see if that'll quiet them down any. But I digress...
So while they stop great, I can't fully endorse that point of view. Any higher performance pad and rotor is going to be noisier and prone to squeel than an OEM piece of equipment or an OEM replacment part. That's just the price for having spleen killing braking power.

Re: Need Help With Brakes STS-V
I have had 0 issues with my hawk HPS pads. Front and rear have both been replaced. We sanded the rotors, all hardware and lubed the sh*t out of the pins, the retainer and sanded the pads a little bit. I also put lube on both sides of the backing plate that the pads and pistons sit on.
We also burnished the breaks exactly how Hawk recomended.
I have heard certain rotor and pad mixtures dont always work well with each other.
Coming to a squealing stop in such a nice car BLOWS! GOOD LUCK!
Thanks for all the input, last thing left is to order some new pads, yeah it is embarrasing coming to a stop in such a nice car and squeal, "like a ship coming into port"...lol, ive replaced everything beside the brand of pads.Ive got the ebc rotors, cross drilled and slotted, any luck with the ebc pads? or hawk's all the way?
Since you were a GM Tech than why not call Luke at Lindsey Cadillac and ask him about this issue. He is a GM parts guy and has extensive experence with
both STSV and CTSV. I have never had any problems with his products. He is a bit expensive so you may want to get a part number
from him and than translate it to a more affordable retailer. One of the authorized vendors here will give you a discount, so it may be
worth a couple of phone calls. If the pads doesn't help than I would say you have issues with the rotors themselves.
I have EBC rotors on my 08 STSV that are slotted and dimpled. The combo has never given me any of the problems you are experiencing. The vendor I am recomending is StreetSideAuto.com Hope this helps I know what a pain in the a.. this is.
I don't think anyone with any car since like this noise. Best of luck.

Re: Need Help With Brakes STS-V
I have hawk hps on my c5 vette that has the c6 zo6 big brake kit on it. I drive this car hard stops from 150 plus all the time and autocross it. no noise at all they get so hot the Rotors glow red. Had hawk pads on my 750il BMW and that had $400 eBay rotors on it and they made noise for abought 500 miles then went away. The v still has factory pads for now and they make noise under 20mph but not to bad it will get hawk in the spring.
The noise is coming from the pads or caliper vibrating in the bracket make sure u lubercate youre slides u can also champher the leading edge of pad this may dampen the noise also brake compound may play a part in this get a softer pad make sure the rotors are smooth meaning resurfaced or new also durring break in 20 to 30 light to mderate stops with time in betweene for the pads to cool
