Hard (power) brake pedal

It turned out outstanding. The diaphragm was leaking.
It's nice to have brakes that actually work for a change and the booster looks brand new.

I highly recommend Booster Dewey if you have a booster that needs restored or rebuilt.
Glad to hear it worked out. I have mine down at brake booster exchange in Oregon seeing as I am on the west coast. Exact symptoms you had.
