F-Body Road Racing and Autocross Forums _ General Discussion _ A solution for pad knockback found?

Posted by: FASTFATBOY May 9 2012, 01:16 AM

This system was installed on GM and High Tech Performance's STI Killer with a stock 10 bolt.

No idea on cost.

Also in the GMHTP article they refer to something called a "VeriSlide" for the rear, used in place of the Baer kit.

From reading the article , the Veri slide is a floating caliper bracket .

It says $1650 in the Baer link.
Not too far from a c-clip elimanated 12 bolt .

Granted I have only done HPDE's and open track days, but why have I never experienced pad knockpad?

Sounds like you aren't going fast enough. 2thumbs.gif 2thumbs.gif



Just kidding..

Shoot you can pick up a new 9" full floater from Summit Racing for less than that....

All of the pad knock back issues I've had have 100% been attributed to worn hubs. I learned that it once the hub end play approaches 0.012 (measured at the tip of the wheel stud) it's time to replace the hub before pad knock back becomes an issue.

This is interesting. I know I have massive pad knockback issues originating at my rear axle. For now though, I'll just adjust my driving style and remember to tap those brakes before the higher-speed braking zones...

Maybe not a solution for everyone, but the installation of a Powertrax differential and Ten Factory axles completely eliminated the rear pad knock back due to c-clips. I also added 2psi brake check valves in both front and rear lines.
Can't do much about worn out front hubs though, except replace.
Hope this helps.

Maybe I'm dreaming, but I believe there are some type of springs that can be installed on the pistons to counteract the knockback. Sure you get some pad drag on the rotor, but it's way better than entering the braking zone at 150, in traffic, and the brake pedal going almost to the floor. Anyone used something like this before?

Anti knockback spings.

Springs seem like a neat idea. I wonder how they'd increase pad wear, and rotor heat (since the rotor couldn't cool off with constant friction).
