Default Re: Willwood drag race front brakes

The first thing I would check for is brake drag with no pedal pressure applied. You may just need to shim the calipers slightly, to get it centered on the rotors. If they are off center, the pistons on one side may not be able to retract enough. There is less than a thirty second of an inch movement of the piston, when the pressure is relieved, so you can see how critical having the calipers properly located is. You can also check line pressure at each front bleeder screw, with booster assist and a firm push on the pedal, you should see about 900 to 1000 PSI on the gauge. You as driver should push the pedal and have a friend read the gauge.
