What first happened was I lost almost all of my brake pedal. no noticeable leaks or loss in fluid. I then replaced both the booster and master cylinder and could not get any pedal back. At that point took it to a garage and they sugested that the master cyclinder was bad, so went and exchanged the master cyclinder and the mechanic bench bled it and re-installed. The truck was reyrned in the same condition it was taken to the garage. Still no leaks, and no pedal. Any suggestions?

Did you pull the wheels and check the brakes?

I had the same issue in my 94 xlt F150. It ended up being that the line that leads from the caliper to the resovoir, has a rubber boot about 14 inches up from the caliper. The soldering inside has rusted out over the years and had wiggled loose where It would **** out the brake fluid when I used the brakes. But when I got under the truck to look everything looked normal because it would only happen when brakes were applied.
