1989 Ford F350 V8 Four Wheel Drive Manual 88000 miles
I can't get the brakes to bleed properly. I've replaced the brake booster, master cylinder (new-not rebuilt), vacuum pump(it's a 7.3 diesal), both rear wheell seals, several sections of tubing (due to rust) and a rubber hydraulic hose at one front wheel. The proportioning valve is bypassed by manual gizzmo that controls the amount of fluid going to the rear brakes.
I tried to isolate the front from the rears by plugging the rear oriface at the master brake cyl. This produced a harder pedal but I still couldn't get the wheels to lock up.
I had the vacuum pump and rear wheel cylyinders & bypass gizzmo intalled by two different shops. I'm stumped. Any suggestions will greatly be appreciated. You might want to know this vehicle came from the north and is very rusty. It has low mileage and steers good but sat up a good part of the time because it was used as a snow plow (4WD)
have the same problem?
