Has anyone just tossed their prop valve and used an adjustable valve like the drag racers use? My brakes suck. I put one tons in and a one ton master. I haven't done the booster yet because the the problem seems to be more in the fluid system than the assist. I have bled, bled, gravity bled, replaced the master, and the pedal is still soft and moves way to much before the brakes grab. Another reason I am questioning the prop valve is the reset button on the end pulses when I push the pedal, and leaks from the same spot. SO, can I axe that sucker and put the wilwood one in the rear brake line?
