The brake dust from the AC Delco pads are crazy bad. Can anyone recommend a good high performance (obviously without the vibration that 2016Caddy notes), low dust alternative?

So the OEM AC DELCO brake pads are made by BREMBO (part # 171-1040) for the front set & BREMBO also sells direct.
AC DELCO pads are $207 on Amazon
The BREMBO Pads direct have two options, one is $159.00 other is $189.00

What's the difference?

I've tried the Power Stop Z26, but at high speeds or high heat conditions I'm getting vibration, that goes away once they cool down a bit, but want to go back to OEMs.

Thanks!
Looking at the detailed descriptions, the P37018N is a ceramic pad and the P37018 is the OE pad. The P37018 description page even lists the correct GM part number for the OE pads (2525940447).

i also have the powerstop and i also get the vibration like you sometimes.
i thought its because i install the pads on used rotors without getting them resurfaced .
you install the pads on brand new oem rotors?

No, but rotors were inspected & passed QC by tech. Only issue at high speed or road course driving when they get the hottest average temp. Feel the Z26s are way too soft when cold too. Highway exits can be scary if you drive like brakes are warm & ready.

I work for ZF, and heard about this new line of TRW brake pads.
Just wondering what the community thinks about them.


Thanks all!

TRW (Thompson Ramo Wooldridge)(1958 partnership) has been in the parts business for a very long time. I would not hesitate to use their products. I remember the "name" from my part-time auto shop work in the early/mid 50's.

I see that ZF/TRW is now one company.

Brake dust is actually mostly rotor-material that has been shaved off by these lovely, aggressive and very effective OEM pads. More brake dust=more work being done. It is why Porsche has specially-coated ROTORS to reduce dust on for their white calipers ;)

LOL, brake dust is not rotor material. The reason your brake pads have to be replaced is because that's what's wearing out. If the brake dust that forms on the wheels were from the rotors you would have no rotors after 6 months. There may be a trace amount of rotor material in there but not even measurable compared to the dust from the break pads. That's why when you change to ceramics the brake dust disappears.

I've been using the powerstops for a while now and I never get vibration. I made sure to bed them in properly. If you do aggressive stops often enough to generate serious heat, like on the track, you need to go with a higher performance pad like EBC or Hawks

I had the Brembo brakes on my ATS and now on my CTS. Original pads on both, traded the 2013 ATS in for the 2016 CTS with 63,000 on it, and as stated, still the original pads. The CTS is at 62,000 right now and still the original pads. To me the pads that come on the factory Brembo brake setup are the best, stop on a dime and I don’t understand what people are saying about brake dust. To me that’s one of the best parts of these pads, there is practically no dust. Personally I wouldn’t even consider anything else when it’s time to replace them.
To the guy that thinks it’s the rotors that are wearing and dusting all I can say is ..... ahhhhh.....no. Your mistaken.

Now I have heard it all...."brake dust is rotor material be shaved off"....WOW :rolleyes:
Sorry fellas, but the guy is correct.

"EBC Brakes have conducted tests on brake dust and found that over 90% is the element Fe which is iron or steel ferrous elements and must have come from the brake rotor itself. This leads us to the conclusion that brake disc or brake rotor abrasion is key to the amount of dust generated. By reducing disc or rotor abrasion brake dust can be therefore significantly reduced and by using a lower pad content of carbon materials or steel fibre the dust can be almost totally eliminated."

Bro can you imagine if that was true swapping rotors instead of brake pads

All you knuckleheads realize your rotors do wear, right? Or have none of you ever had to replace any brake rotors before? The discard thickness is usually 2mm less than the new thickness, and that's 2mm spread over a much larger surface area than than of the brake pads - that's quite a bit of cast iron. I'm not sure I believe the 90% number from collinsr's EBC quote about how much brake dust is due to the rotors - seems to me that number would vary a great deal depending on the pad compound and the vehicle usage - but there is obviously cast iron wearing off the rotors, and that's going to be mixed in the brake dust. I've seen rust along the side of light-colored cars at wet track events because of the rotor dust being blown back onto the paint.

:unsure: I'm not sure why you think the rotors would be wearing out in 6 months; as I said above, the rotor wear surface is probably 4x larger than the pad wear surface (and probably even more than that on cars with smaller calipers), so there's plenty of rotor material to wear away.
And the ceramic pads are also less abrasive and more gentle on the rotors, hence less rotor dust.

Well, you're posting in the ATS-V forum, so the obvious reason for the difference of opinion is that your CTS doesn't have the same pad compound as the ATS-V. Your CTS has ceramic pads, the ATS-V has semi-metallics; the latter as a general rule pump out a lot more dust.

Actually yea I do swap my rotors out I check mine every third oil change looking for uneven wear etc and on my other cars like my Dsm when I started pushing past 600hp I upgrade to a big brake setup and swapping to steel braided line all the way to the proportion valve like how I got just bought my Escalade this month I have pads and rotors waiting for it when the next oil change comes rotors look fine but pads look like there oem so I’m gonna change them out

Yeah, if there is some statement by EBC that says that I'm not buying that at all. There's a time where no matter what someone's data says you have to face common sense. I've been through more pads on my cars then I can remember and I can't think of any but one time I had to replace the rotors and that was due to damage. The break pad is the softer element that is designed to wear first. All of the material that gets on your wheels is from the brake pad with a small amount of rotor material. That's why when you change pads to ceramic it stops. The amount of brake dust that our car puts out would wear out the rotors in 6 months or at least compromise them if it were 90% of the material. That's is if you actually drive your car.

For the one article you read in EBC I can provide 10 from other reputable sources that say the opposite. Also, quoting EBC, "
99% of automotive brake pads made these days are made as a semi metallic meaning a bundle of steel fibers compressed and fused together with other additives. The steel fiber content can be up to 30% of the pad".
Steel is made from purified iron so to make a claim that the dust is mostly from the rotors because they found iron is a odd conclusion since the pads are the softer material and are made from iron fibers that wear and break away much easier. This is why pads with higher metallic content yield more brake dust.

Now does a higher metallic content pad cause more rotor wear, sure it does because its more abrasive making it brake harder, but that doesn't change the fact that the pad is still the softer material and will yield most of the dust as they wear out.

I really don't understand how this is even a conclusion, unless..., maybe the person making the conclusion also sells rotors?

You do understand that the brake pads are mostly metallic (steel=iron).

No one argued that rotors wear, its the claim that brake dust is mostly rotor material that seems absurd, other than one persons article from one manufacturer that sells rotors
