RABS Valve Problems
I have a 1990 F-150 4X4, I think the 
RABS valve is shot. The rear brakes drag to the point that they are smoking. I have replaced calipers, shoes, pads , sensors , you name it and the darm thing still is dragging the brakes. If I totaly eliminate the RABS from the system will this affect the braking aside from it behaving as an older style system ?

is your e-brake sticking,????? a rusted cable, or are you adjusting the rear brakes wrong, i wouldent thing the valve would not allow fluid to travel back to the MC. Did you put a spring kit in there when you did the brakes? a weak spring will cause the brakes not to fully retract.

I replaced springs and checked the cable too. Just finished by-passing the RABS and road testing, the truck stops very well, pedal is still a little low, but I am having the system flushed as the fluid that was in it looked bad, so I'll let the shop guys handle it from there.
