Hi everyone. I noticed an odd behavior where if I'm driving a while without using my brakes, the pedal is low when I step on it. The brakes work just fine if I push -- they don't fade -- the will stop the car. I cannot heel-toe with the brake pedal that low though. A quick tap brings the pedal right up where you'd expect it. I sometimes tap with my left before braking so that I know what kind of pedal to expect.
I thought about what might cause this for quite a while, and came up empty. The master cylinder would give me low pedal and brake fade, maybe. There is some kind of vacuum assist and I have no idea how they work but found no logic to it.
I asked around a bit and was suggested the idea that maybe turns and bumps (my race suspension is seemingly made of welded iron) might be pushing the pistons back into the calipers from things flexing around the rotor. I did some research and pad kickback is a thing. Maybe my wheel bearings are a little loose?
I'm just putting this up in case anyone has any better guesses to the problem or if this is a problem you've run into, what was the culprit?
Thanks!
