The brake drum should first be taken off, and the brake assembly then cleaned with brake system cleaner, allowing the residue to drain into a drip pan to replace the brake shoes. Check the depth of the friction material on the friction shoes of each brake shoe at various points; in case any shoe becomes thin enough to reach a certain minimum or below change all four shoes as a set. Wear new shoes, which are not oily or greasy, because it is not possible to clean such oily and greasy shoes. When wearing any shoes in uneven manner or being dirty, find the reason and fix it first then put back the parts. Fit the brake drum provided that everything is in good shape. Record the location of the brake shoes and springs and potentially mark the webs. Depress and 90 degree rotate the hold-down cups and springs with a special tool or pliers. Unscrew the springs and the holders at the lower end, and then slide the shoes off, one after another, at the bottom end of the pivot, so as to relieve the tension of the return spring, and to detach the lower return spring on each side of the shoes. Be careful to take out the upper part of the two shoes in the wheel cylinder positions carefully, not to tear the seals, remove the parking brake cable in the trailing shoe. Installation Maneuver the brake shoe assembly off the backing plate without pushing the brake pedal and hold the wheel cylinder pistons in place with an elastic band. Record the appropriate correctly installed positions of all parts, disconnect the upper return spring, and the wedge key spring. Disengage the tensioning spring, and take out the pushrod of the trailing shoe, with the wedge key. Inspect everything that can be worn or damaged, and change it when needed, and change all the return springs no matter how they are. Inspect the wheel cylinder, whether there are leakages or damages and both cylinder pistons should be free. Use brake grease of high temperature on the contact points of pushrod and parking brake lever. Tensioning spring Hook the tensioning spring through the trailing shoe and fix it to the pushrod and pivot it in place. Install the wedge key correctly in between the trailing shoe and pushrod but have the raised dot away facing the shoe. Find the parking brake lever in the leading shoe in the pushrod, and fit the upper return spring. Insert the spring to the wedge key and attach it to the trailing shoe. Wipe down the backing plate and apply a light coating of high temperature brake grease or anti-seize compound to the contact points of the shoes, without touching the friction material. Take the elastic band out of the wheel cylinder and place the shoe assembly there, and connect the cable of the parking brake and find the place of the top of the shoes in the piston slots of the wheel cylinder. Put the lower return spring between the shoes, push the bottom of the shoes against the bottom anchor, tap the shoes so that they are in the middle of the backup plate and install the shoe retainer pins and springs with the spring cups holding them. Lastly, fit the brake drum, redo the same step with the rest of the rear brake, adjust the clearance between the lining and the drum by pushing the brake pedal until normal pressure is achieved, inspect and adjust the parking brake should need be and verify the level of the brake fluid. The bedding-in period of new shoes will be necessary so that the first hundred miles after replacement should not be hard braked.
