I installed Wilwood disc brakes all around. I had front disc rear drum before. With the stock master and prop valve the back brakes were grabing harder under firm braking. It felt weird. I just added an adjuster in the rear line and now I'm getting the front nose dive under firm braking. Feels more like normal braking. The rear brake are working since the rotors are hot to the touch. Is there a way to adjust for proper front rear pressure with out taking the car out and slamming on the brakes?
