So how do lesser vehicles manage to not have brake squeeeel? Mine have done it since I bought the vehicle @ 15K miles , replacd pads at 20 with GM Ceramics, and now with 36K, the only time they are quiet is when its parked. I may try the 60-0 and cool down period, I'm sure I read somewhere you have to do 60-5 3 or 4 times (without stopping) to line the rotors.
PS: Lesser vehicles have squeal also. My truck is a prime example. Of course it is also a performance application that has to stop 26K lbs.

Brake pads and even kits have different methods for bedding the pads to the rotors. My Stoptech bedding instructions were substantially different than the AP Racing. The key is that you want to get the rotor hot and deposit an even layer of pad material on the rotor.
Pad to pad is what stops you efficiently (cohesion) as opposed to pad to rotor (adhesion). You also want to completely cool the rotor. I jump on the highway for 20 minutes and then depending on the looks of the rotor, I'll bed them again. Some prefer to wait overnight before a second (or third) bedding.
Don't cook the brakes when you're bedding. If you can smell the brakes or get a lot of fade, you're done. Some amount of fade is to be expected. That means you're close to done. Hope this helps.

I got a question? I have a 09 z51 and have about 25k on it. The pads are the stock pads and I was looking last night and could really see it the pad are about done or not. So, my question is. If I have been driving semi hard no racing how long should the pads last?
