Power Brake Booster

[George R]

What would cause the power brakes to remain applied after releasing the brake pedal on a power brake car?
If I disconnect the vacuum hose to the booster, the pedal returns to the top normally.
Any ideas?
Thanks,
George

Bad check valve on the end going into the booster??

Good idea Adam. I'll check that out for sure.
