Brake question

I have a CPP dual reservior power assist brake setup (front disc rear drum) installed in my 55 f100.

When the truck is running (i.e. the power booster is boosting) the brake pedal does not return to the upright position on its own, it will come up some but not all the way. The pedal returns to the proper position if the engine is not running (i.e. no boost)

It holds enough pressure to keep the truck in place at idle in gear.

any thoughts?

how old is your fluid?

I'd say its your booster. The return spring may be bust.
