Question about 1992 Ford F250
Thanks to all who have helped me with this. Please tell me how the power booster could be related to the loss of pressure. There is vacuum at the booster and no obvious leaks. The pedal is hard when the truck is not running. As soon as it starts you can push the pedal to the floor. I don't understand how a problem with the booster has a relation to the plunger moving too far in the cylinder. Please explain as I could see if there is a problem with the booster that I would have a hard pedal but not soft. Thanks again. Reg.
If your pressure is good in till you start your truck it is the power booster. i just fixed this problem. If it is not your master then that is the problem. I had to replace the whole brake system to find this out.

All a brake booster does is boost your peddal effort .
so it can not be related to your fluid pressure loss.
my question is are you loosing brake fluid?
its possible you have a bad master cyl or you need to bleed your brakes.
let me know if ya need more help
