Removal
1. Raise the rear of the vehicle and secure it on stands. Remove the corresponding rear wheel.
2. Remove the screws securing the brake drum to the hub.
3. Check that the handbrake is fully released and remove the brake drum from the car. The drum may not be easily removed from the hub due to corrosion of the hub or because it is held in place by brake shoes. In the first case, tap the drum around the perimeter with a plastic hammer or wooden mallet to remove it from the hub. In the second case, make sure that the handbrake is fully released and do the following.
4. Loosen the handbrake cable adjuster completely to obtain maximum deflection in the cable. Remove the plug (A) from the rear of the brake shield (the cork is usually coated with blue paint) and, using a screwdriver, move the handbrake lever towards the brake shoe until it stops. This will allow the brake shoes to move away from the brake drum, allowing the drum to be easily removed from the hub.
Examination
1. Carefully clean the inside surface of the brake drum from brake dust and dirt.
2. Clean the outside of the brake drum and check for obvious signs of wear or damage, cracks around the wheel bolt holes. Replace the drum if necessary.
3. Check the inside of the brake drum. Some wear on the drum from the action of the shoes is normal.
4. Measure the inner working surface of the drum in several places. Compare the results of the measurements. If the results differ from each other, the drum is oval. If the measured maximum size of the inner diameter of the drum is within the permissible limits, it must be re-ground. If the drum wear exceeds the permissible limits, it is necessary to replace the brake drums on both rear wheels.
Installation
1. When installing a new brake drum, use solvent to remove the protective film from it. If necessary, reduce the length of the brake shoe adjusting bar by turning the bar adjusting wheel.
2. Check that the handbrake lever is positioned against the edge of the brake shoe and that the working surfaces of the brake drum and hub are clean and dry.
3. Install the brake drum onto the hub and secure with screws, tightening them to the required torque.
4. Press the brake pedal several times to activate the brake shoe clearance adjustment mechanism.
