I was having some issues with my parking brake, which might have been a combination of adjustment at the handle and/or at the shoes. I knew the front rotors and pads were new when I purchased the car, but the history of the rears were unknown and they looked worn. I decided to replace everything back there, including new brake rotors, pads, sensors and parking brake shoes. The parking shoe kit included new springs and retaining screws, which all looked a lot better than the old rusty ones.
I even got an assist from a very special helper.
