Official: Brake Pad Knock Back Thread

[DOOM]

I think Todd has thrown just about everything at this issue....

Yep, the rear bearings have loosened up. I've even thrown some shims behind the races with no noticable change. I want to go floater but hear a certain someone may have a solution in the works. (not me)

I adapted these to work on my car, it’s not a kit but just some parts that I made work, I had to make my own brackets, knockback is gone and the car stops amazingly well.

Rick, thanks for sharing your idea. I'm just not sold on a smaller rear caliper as hard as we run these cars.

Todd I agree with you but this did eliminate the problem and overall my brake performance is way better then when i had the 4 piston rears, another problem with this small calliper is they dont make an aggresive pad for it.

I will continue to work on another setup involving a 6 piston caliper that i can convert to a floater, more like a floating bracket.

Todd, you've been dealing with this problem for what seems like forever. When I started having knock back issues this thread was a wealth of knowledge on the situation. I read this whole thing over carefully, and went back and forth on how I was going to try to address it. Having seen all of the work that you did to try and find an adequate solution, I decided to go with a floater. I wasn't sure whether or not it would be overkill. Yes, tapered bearings and a 1" master cylinder have worked, Bad Penny being an example, but I didn't want to run the risk of having it not work, leaving me having to put up with the problem, or throw more money at it.

From the four autocross runs I did before I had to retire my car, I can tell you I didn't have any problems with the floater under the car. Hopefully nothing pops up after more track miles! I know you're tired of spending money on the car, but IMO the presence of mind in knowing that you wouldn't have to screw around later would be worth the 1500-2000 for the floater.

... You probably didn't need my little testimonial though
Feel free to give me a call if you are seriously contemplating the change, or give the guys over at Wilwood and Speedway a call. They worked together every step of the way, and came up with a solution that was very reasonably priced considering I replaced everything except the third member.

Matt, I appreciate your insight. I did speak with Dustin at Wilwood at the event and he mentioned they could adapt a floater to my caliper. Put some more miles on your set up so I know it's a sorted out fix.

Apples and oranges buddy...
