I have an 86 GN with Hydroboost, front s10 calipers and rotor conversion and wilwood rear disc brakes. I also changed my proportioning valve to the wilwood factory style with adjustable rear proportion valve. The car stops fine but I cannot brake torque the car at all. The rear brakes don't seem to have near the same clamping force as when I had the powermaster and drum brakes.
Need more rear brake pressure
