Re: Wilwood front discs sticking on
While I agree the prop valve looks wrong, that should only affect bias front to rear, and have nothing to do with releasing the brakes. I think you have a constant pressure problem pushing on the brakes all the time ever so slightly which gets worse as the pads get hotter and hotter and grab more and more. Sounds like the push rod in the booster is too long and is pushing on the piston in the master. Take the master loose and see if you push it tight to the booster by hand if it trys to spring back away from the booster right at the bottom. If so the rod in the booster is too long and your never completely releaseing your brake. As i said, cold, you can drive through it. but the pads are designed to get mnore aggresive as they get hotter. Hence why it gets worse longer you drive it.
A quick test is remove the master (do not have to remove the lines) and put a thick washer (lock washer is perfect) between the master and booster. And try that. If that makes it better, you will have to grind the rod coming out of the booster down to fit.
