GM went to a stiffer front wheel bearing on the ZR1, STS-V and CTS-V to fix brake knock back.
The bigger the rotors the bigger the problem.
2 psi valves won't do it
The test I use is to do a figure eight in a parking lot at max lat then measure the brake pedel travel.
If you can't fix the problem learn how to left foot brake on the straights to pump up the brakes. I have done this for years.

Hi Mark,
Do you know the GM part number for the stiffer ZR1 front wheel bearing?
I want to make sure I have the right ones...
