Brake Pressure Bleeding Off On '94 F250
When I hold pressure on the brake pedal with the engine running, the pedal slowly goes to the floor.
There are no leaks, so I assumed the master cylinder had to be bad and replaced it with a new one. --- Same problem.
Any Ideas????

Ah Ha!
Just now went back out to truck and had wife operate pedal while I looked around for a leak and I found one. Fluid is dripping out of the newly rebuild master cylinder where it attaches to the power booster.
How often does something like that happen?
It must mean that the new unit is also defective and fluid is getting around the pressure cups inside the bore.
Anyway, I called the parts supplier and they have another unit on order and will swap out with me when it comes in Tuesday.
