Do the shoes drag slightly when you're > off the brakes? They should... MCs made for front disk brakes have NO residual pressure valve. These really aren't necessary in the older cars either. I have never understood why they were EVER used in any of our cars. The head (pressure) from the installed position of the brake fluid reservoir makes them unnecessary. You don't want any residual pressure holding your pistons out at all; it is important that the drum brake wheel pistons (unlike the disk brake pistons) retract COMPLETELY into their cylinders when you lift your foot off the brake pedal. When the brakes are off, there should be no drag at all between the shoes and the drum. Even a small amount of drag can eventually cause the brake to overheat, boil the fluid, and cause loss of braking. Been there, done that! >8-0 Jim - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
