2005 Buick Rainier Parking Brake Shoe

You should release the park brake, raise and support the vehicle, remove the wheel and the tire, the brake caliper and bracket, the brake rotor, and the park brake cable, slide the park brake shoe down, lift the shoe away from the backing plate, slide the shoe up off of the actuation mechanism, remove the shoe over the axle flange and from the vehicle, clean the debris and the dust from the park brake components using a clean towel, turn the adjustment screw to the full home position in the notched adjustment nut, then back it off 1/4 turn, align the slots in both the adjusting screw and tappet to be parallel with the backing plate face, clean the rear backing plate of dirt and foreign materials and dry the backing plate.
