Thanks, Jerry! I'll get the cylinders fixed and brakes adjusted. I've never noticed any increase in engine RPM while braking, nor any white smoke so I guess the Hydro-Vac is good. If something should happen to it or the master cylinder, would it likely show symptoms to provide warning, or could it be an immediate loss of braking?

Also, I know to adjust the brakes you turn the star wheels on the cylinders, but how do you know when the minimum clearance is reached? Is there a guide on the forum here somewhere?
