How to Replace Auto Rear Drum Brakes

In most cases, replacing brake shoes and drums will correct problems with rear drum brake systems. Since your safety and the safety of passengers in your vehicle depend on a reliable brake system, you should not attempt to replace brakes until you are certain of your ability to do so. Familiarize yourself with brake parts and repair tools before attempting to remove the brakes from your car. Drum brake systems can vary by manufacturer and vehicle type. Consult the owner's manual for your vehicle regarding its brake system.

Instructions

1

Park the vehicle on a flat surface. Use a car jack to lift the vehicle's rear tires from the ground. Ensure your personal safety by using jack stands to secure the vehicle on both sides.

2

Remove the rear tire. Use a tire iron to remove the lug nuts. Pull the tire off the vehicle to expose the brake system.

3

Prepare your work area. Lay out a light-colored sheet or drop cloth or clear an area of workspace on a bench or other surface. Place all parts on this work surface as they are removed from the vehicle. You will also need to place an old sheet or drop cloth under the rear of the vehicle. If you plan to detach the brake line, be aware that brake fluid will leak out onto the surrounding area. Keep several rags handy for cleaning parts, wiping hands and cleaning up leaks or spills.

4

Remove the brake drum by pulling it towards you. In most cases, the drum should come off with minimal difficulty. If you have trouble getting it off, you may need to use a brake drum puller. This tool is available from most automotive stores. Inspect the brake drum for damage or signs of wear.

5

Use needle-nose pliers or a brake spring removal tool to remove the brake springs located on either side of the brake shoes. Visually inspect both brake springs for damage. Place undamaged springs side by side on your work surface if you plan to reuse them.

6

Remove the retainer clips with a socket wrench or brake shoe removal tool. Press down on the retainer clip and turn it in a counterclockwise motion until it comes off. Remove the retainer clip springs. Visually inspect the retainer clips and retainer clip springs before placing them on your prepared work surface.

7

Remove and inspect the brake shoes. Brake shoes that show visible signs of wear should be replaced. Remove any remaining hardware at this time. Depending on the make and model of your vehicle, there may be additional small parts to remove. Take note of where these are located in order to ensure they are replaced correctly during reassembly.

8

Use a line wrench to remove the brake line from behind the wheel cylinder. Locate the nut that attaches the brake line to the cylinder. Use an adjustable wrench to turn the nut until it comes loose, freeing the brake line.

9

Locate the mounting bolts on the wheel cylinder. Use the adjustable wrench to loosen the bolts. Remove the wheel cylinder and inspect it for leaks or damage.

10

Use rags to clean the brake shoe backing plate before reassembling the brake system. Reassemble the brake system by replacing the wheel cylinder and reattaching the brake line. Tighten the nut holding the brake line firmly to prevent potential brake failure. Replace other parts of the brake system in the reverse order of removal.. Ensure that each part is in proper working condition prior to reinstalling it. Bleed the brake system before driving the vehicle.
