10 blazer: I loosen the rear parking brake shoes..2005 chevy..rotors

This answer was rated:

How do I loosen the rear parking brake shoes on my 2005 chevy s-10 blazer? I am trying to change the rear rotors.

Hello, and welcome to JA!!! there is really no way to back off the rear park shoes. there is a adjustment for the park shoe, but can only access after the rotor is removed!!! if the rotors is stuck, trying tapping on the rotor with a hammer!!! sometimes during removal of rear rotors, the park brake shoe's will get damaged. it is always a good idea to replace the rear park shoes, while working the rear brakes!!!
