#38 of 44 F-250 diesel intermittent brake problems by thekraut

1995 Ford F250 diesel has brake problem, sometimes brakes work OK, sometimes the pedal is hard as a rock and goes all the way to the floor before brakes work, sometimes a slight delay and then brakes work. Very scary not knowing what will happen when I touch brake pedal. 2 mechs recommend replacing brake booster, vacuum pump, and master cylinder, (not in that order). Very expensive to start changing these.

#39 of 44 Problem with Ford F150 ABS braking system by lniehenke

The left disc brake is pulsating when I try to stop. I removed the fuse that controls this ABS braking system. A indicator light on the dash comes on indicating that the system is not powered up.
The pulsating problem is resolved but I don't have a ABS system. Is this a sensor problem on that left front brake?
How hard is it to replace the brake sensor?

#40 of 44 Getting Access to the ABS Module (1999 Econoline 150) by petecal

My ABS light is on. I think it is a loose connection at the ABS module. (Long story I won't bore you with).
 
It seems the ABS module is attached below the Hydraulic Control Unit and very hard to get to. I am sure I have to move the HCU but it has a few hydraulic tubes connected to it and I can't remove those (cost for dealer to bleed the system) nor do I want to break one.
 
Does anybody know if things can be loosened up enough to get at the ABS module without damaging the HCU connections?
 
Thanks In Advance,
Pete

I am working on a freind truck that has the same peoblem. It does the same thing. There is something inside the frame rails under the mastercylinder that the brake lines go to. It says remanufactured and there is a harness going to it It has no power going to it with brakes on or off. It also looks like it has a small motor conected to it like a small pump solenoid. I'm trying to find out what it is and if it has anything to do with the problem. Maybe it can help you. I'm open for any info on this problem.

That is the ABS unit. There is a harness, yes, but there is also a power connector.
