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!
