Yes. I'm going to try that tomorrow Dave. I did buy a gauge kit as you suggested a while back. The pressure should peak when pedal is pushed in, shouldn't it all but disappear when pedal is released since its a disc brake? I was told that disc brakes have no residual pressure valve like drums do. I just have to get the young man back out to shop. Lols. He's afraid it'll never leave the shop again.
