I have a 96' Ford E350 Club Wagon. When I press the brake pedal the brakes work great however the pedal does not return fully.

I have bleed the brakes, exchanged all the old fluid, checked the few rubber brake lines it has, replaced the brake booster, adjusted the booster arm length both in and out and nothing has changed it! it has no return spring on the pedal nor a place to mount one.

I am about to replace the master cylinder but would like some insight before going through with all that work and extra $. When removed, the master cylinder does extend all the way back out. When I remove the vacuum line from the booster the pedal will return all the way back.

let me know if any more info would be helpful.

Thanks!

Since the brakes stay on, it could be the brake booster is assisting when it shouldn't. To verify this, you could disconnect the vacuum pipe that goes to the booster to see if the pedal the raises. You will need to cover the end of the pipe while you do this to stop anything being sucked into the pipe. Another thing that could identify the booster being at fault would be if the pedal returns to normal position after the engine has been turned off for a while.

I think Paulster2 is on the right track. If you cannot find the spring possibly it broke, fell off and is gone. Might be worth a trip to the Ford store have a partsman look up all the brake linkage parts, there will be a picture showing where the spring goes, what it looks like, etc. At least if there is no spring required, the partsman would be able to verify that for you.

It seems if the pedal pivot was rusted up. Booster helped but did not fix it. Sprayed the pivot with PB Blaster and it was better. Not great but better. Thank you for everyone's help!
