  Q: How to Properly Service and Replace a Parking Brake Shoe on Buick Rainier?

  A:

  Start replacing the park Brake Shoe by rescinding the park brake then lifting the vehicle while ensuring that the brake remains off. After wheel removal the brake caliper combined with bracket must transfer to the empty wheel position without disassembling components. The first step involves removing the brake caliper along with its bracket as well as the brake rotor. Start by detaching the park brake cable from the lever and then slide the park Brake Shoe down from the hold down spring to disengage it before lifting it away to slide off the actuation mechanism . Use a clean towel to wipe off debris along with dust from all park brake components while these components sit on top of the axle flange. Adjust the screw adjustment until it reaches the extreme end of the notched nut before rotating it one-quarter turn counterclockwise to achieve parallel orientation of the slots relative to the backing plate. Dampen the rear backing plate with denatured alcohol followed by airflow from non-lubricated filtered air until dry. A new park Brake Shoe should be positioned over the axle flange while it receives placement on the actuation mechanism. Push the lower shoe away from the backing plate before lowering it down above the hold down spring and set the low end against the plate for a final upward slide underneath the spring. The shoe assembly must be placed in the middle of the backing plate so both actuation mechanism slots align with the tips. The park brake manual operation requires observation of the actuation mechanism when the technician moves the park brake actuator lever. The park brake cable should be connected to the park brake lever while adjusting the park Brake Shoe and reinstalling the brake rotor alongside the brake caliper and mounting bracket and tire and wheel. Finally, lower the vehicle.
