I just picked up an sti as the title says. There had been a bunch of snow and ice theday iI got it. So any chance of me hearing any flaws were limited. It is a certified pre owned car so anything wrong with obviously be taken care of. But they won'tbe able to get me in for a few days anyhow.
So on to what's happening, when I come to a slow stop It sounds like a quiet grinding almost like a rock in a pad or a cracked pad even. I pulled the pads off, they did have a bit of build up on them. And a couple rotorshad small groves . Nothing bad though. I cleaned everything up there really good. Put em back together and no grinding sound, but my brakes were not as good . After a few miles the brakes were grabbing really good again. But the grinding sound was back as well. It's almost like the compound of these pads are just really hard. So hard that the rotors it appears are wearing more than the pads.
I thought of just replacing the pads. It is possible the previous owner put different pads on. The car came with two sets of wheels and tireswith some very track ready rubber.
Anyhow like just wanted someone's opinion on this with a little more knowledge than myself on these cars.
Thanks in advance
