Units with 4 wheel disk brakes may develop at situation where the park brake does not hold as it should. Our technicians tell us this can be caused by worn park brake shoes located inside the drum section of the rear brake disks. The worn shoes should be replaced and properly adjusted to correct this issue.

Parking brake always from day one never worked right. Pedal always went to the floor. Replaced parking brake a few years ago and still have the same problems. Feels like only one side is partial working.
Same thing. My parking brake wont set.
