Z06 Pads squeak
Hey guys,
What's the deal with my (C5) Z06 pads squeaking in the front all the time? Not a year ago I installed the new pads and rotors and even lubed the pad backing plates to limit squeaking.... Now they squeak... Is this typical of Z06 pads?

Not totally sure, but I have your same squeak... The brakes feel firm and visually there's still a good amount of pad left...
Baers and Hawks about to go on though, never had a problem with those on my old F-Body!

These are Ac delco Rotors (only about 5k on them) and GM Z06 pads (also new). I should really just take them out, sand the glaze off the pads and re-lube the backing plates - that would do the trick. I understand the composure of these pads is more for performance, which means higher probablility of squeaking. Just wanted to see what all of you guys are finding.

Same issue with our 00' Coupe........1/2 used Z06 pads due to a 2 day HPDE

Those in the know will just hear the squeak and know your brakes are hardcore

either metallic or ceramic.. The actual compound has a high level of frictional force all by itself.. but without the additives you would only get 1/2 of the pad life. the metalic or ceramic all by it self has a very low frictional coeffiecent. try stopping yor car with a couple of ceramic tiles instead of regular pads...the tiles would heat up and take five times the distance to stop.
IN the Case of the ACdelco duramax pads, the additives can get work hard, and have surface tension...while the compound is soft the additive gets hard... once harder than the rotor they make noise.. some times this hardness can go 20 or 30 thousands deep.. You can try to sand off the surface to remove this hardness...some times if its just starting it is only a few microns deep.. and you can bring them back to their original hardness. (softness )
BMW did a study on pure frictional pads... no addatives... they reduced stopping distance buy 20 % but pads were only lasting 3000 to 5000 miles.

I wonder why the track guys don't use a softer (better stoping) pad. Sure it won't last long but its easier than swapping out rotors all the time which is what they do now!!!
