1968 PB Booster

[franklinair]

I just received a msg from the current owner of my Black GT/CS regarding brake operation:
She says that after applying the brakes the pedal does not retract to the 'up' position, requiring her to
lift the pedal back up with her foot (brakes work normally when the brake is applied & released).
IIRC, the Booster basically consists of the vacuum diaphragm and a return spring. My suspicion would be
a failed (broken) return spring. Thoughts?

Could it be the master cylinder? Low on brake fluid perhaps?

Had that problem once, it was a defective booster.

+one on Marty. But it can be the adjustment of the rod from the vacuum booster to the master. If wanted I can post the adjustment.
