Hey everyone,

I know that this is a Dodge forum, but I am having an issue with my old FORD work truck. I am completely baffled by a brake problem I have with my truck. I completely lost brakes yesterday. I looked in the new master cylinder I replaced this year, and found the front reservoir completely empty. I traced all of the lines back only to find all intact. I bled all four brakes twice. I test drove the truck and the problem persists. Could my brake booster be bad? I can't figure out where the brakes would be leaking if I can't find a leak within the lines. I did notice that when I had my son step on the pedal, brake fluid leaked out past the gasket of the cover on the master cylinder over the front chamber. I am going to start with bleeding the system again, but am baffled by this problem. I did not find any leaks arond the front calipers, or from behind the rear drums.

Thanks for any help you can provide!

if its leaking out of the master than thats probably your problem. how do you're wheel cylinders look?

Sounds like the master cylinder is leaking out the back, i had rebuilt master cylinder do this to me a couple months ago, started leaking out the back before i even got a chance to bleed the brakes. good luck
