Specs callout for 9/32 inch ( .28 inches) shoe lining thickness. At what point should they be replaced? I have specs from of .207, .230 on RR, rear pad and .222 to .230 on the RR front pad. The LR is .234 to .277 rear pad and .227 to .257 on front of LR set.
Trying to resolve a spongy pedal after several bleedings and don't mind having them rebonded to correct specs. Drums are great shape.
Mike B. Yes following the guidelines but must have air entering system somewhere . Still looking and still bleeding…! I was told out of adjustment rear brakes was be an issue. The truck has power disc front and drum rear. I have bench bled the dual M/C and system three times. Thanks.
Make sure that you have full length piston throw in the master cylinder. I don't know which master cylinder you are using or what pedal configuration, but custom jobs can lead to less than full piston travel caused by the sum of all of the modifications. If you have full piston throw, try adjusting the rear shoes until you can't rotate the wheel. This reduces how far the wheel cylinder pistons need to move to make engagement, thus requiring less fluid coming from the master cylinder for bleeding purposes. Back off the shoes to specs once you are done bleeding.
