Wilwood 6 Piston Caliper brake pad question

[ttypewhite]

I have a Wilwood 6 Piston Caliper question. Is there a replacement brake pad I can use that eliminates the subway train squealing noise when they get warmed up? Or any advice on how to address this problem outside of replacing the brake pads? I called Summit Racing and they said that they don't offer a replacement pad for this, other than the one that comes with the big brake kit. Part# 150-10006K is the Wilwood replacement pad that squeals.

I have them on my car and yes I had the squealing also . I started with the BP20 pads ( which are used for higher speed braking with less fade ) and they squealed at slow speed , as in just coming to a stop / parking . I switched to the BP10's which is the standard pad with the kit and it still squealed , so I just lived with it until I went to service / check the pads and when I did a shim washer fell out and I put it back together without it because I couldn't find it . After the service / check I went for a ride and the squealing has stopped and has not come back , it's been 2 yrs now . The car stops just fine slowing down from +140mph in the 1/4 .
I would check the shimming on the calipers and maybe experiment with the shimming .

Interesting... Thank you for your insight. I will give that a check next time I take the wheels off. As you had mentioned. My brakes too stop fine without any noise during regular braking and hard braking. It only happens at the lowest of idle speed when stopping, parking or just applying the brake after creeping forward slowly with no throttle assist. What do you have in the front now for shims if you don't mind me asking? When I shimmed it originally, I believe I did it to center the caliper over the rotor.

It's been a while since I had them off but I believe just 1 shim / bolt

That annoyed me so much pulling into a car show and trying to park !!

I also had plenty of anti squeal on the back of all pads that I tried .
