I had Booster Steve rebuild my booster and my engine supplies about 14 inches of vacuum at idle and the pedal feels relatively hard. I sent the booster back and was told there were no issues. However, to my recollection the pedal was relatively soft when the brakes were applied. The front pads and rear shoes are new and adjusted as they should be, which usually makes the pedal feel firm with little movement. Is that the experience of others, or should I suspect the booster isn't functioning correctly?

Bill, I had a similar issue as your describing and I found that going to a set of Hawk semi metallic pads made the braking less "hard" and smoother overall.

Keith,
I replaced my Midland-Ross booster a few years ago and got a softer pedal and longer stroke.
It turned out to be the rod adjustment was out of spec. Fixed it with the help of the 67 Mustang
shop manual and everything was okay.

After much deliberation and checking my work I found the issue. When the grommet was installed during the rebuild it must have rolled and wasn't sealing around the vacuum check valve. Sometimes the answers are the simplest and you can't always assume that the re-manufacturer/ builder wasn't having a "Monday".
All is well in the land of boosters.

Great you were able to fix it.
