my brakes on my 88' f350 7.3l dsl are crap. pedal is solid until you start engine then it drops to floor. i have been dealing with it for 4 months and there is ZERO fluid loss
here is what we have changed:
master cylinder, vaccum booster, calipers, pads, rotors, wheel cylinders, shoes, ALL lines(except from master to proportional valve and distro block), ALL hoses, proportional valve,anti lock brake fuse.
we have blead OVER 5 bottles starting from the furthest working to the closest, bench blead the master and bled the proportional valve.
Vaccum pump is supplying 27" of vaccum and the one-way valve is working properly.
I got that vaccum reading while ideling in park, should i take readings while driving?
anyone know how the proportional valve works/ the wiring of it or if it works off a certain fuse?
