Learn more One of the most important safety features of a car is its ability to stop. Replacing the rear brake shoes on a car will ensure that the brakes are in good working order and ready to function properly in the event of an emergency.
You can learn how to change rear brake shoes in a professional manner to save yourself money and to help you understand your car better. Even a novice can learn to change brake shoes, provided they have the right tools. In order to do so, you need to remove the brake drums so you can pull out the old brake pads and replace them with new ones.
Start by jacking up the vehicle and removing the wheel to access the brake drum behind it. You can then use a ratchet to remove the axle bearing nut and pull off the brake drum. Then, pull off the brake shoe springs, clips, and cable so you can pull off the old brake shoes. Slide the new brake shoes into place and reconnect all of the springs, clips, and cables so you can replace the drum and axle.

Remove the dust cap with a screwdriver. With the wheel removed, you will be able to see the outside of the brake drum directly behind where the wheel used to be.
The center of the circular brake drum is a removable dust cap. Slide a flat head screw driver into the gap beneath the dust cap and pry it toward you to remove it. Use a ratchet to unscrew the axle bearing nut. Use a breaker bar or half inch drive ratchet to turn the nut counterclockwise in order to remove it. Set the nut aside someplace safe for use when reinstalling the drum. Twist the drum as you pull it backward to remove it. With the axle nut removed, the drum will no longer be held in place, but may still be stuck on due to rust or grime.
Twist the drum slightly as you remove it to break it free from any rust. Spray it around the outside circumference of the drum where it meets the vehicle and give it a few minutes to set in. Then attempt to remove the drum again. Do not strike the drum with a hammer, as it may damage it.
Part 2 of Use pliers to remove the primary brake shoe springs. The primary brake shoe springs are the large springs located beneath the drum once you remove it. Some vehicles will have one spring for each brake pad, while others may have two. All of the springs will need to be disconnected to relieve the tension and allow you to remove the pads.
Try not to bend the springs out of shape, as you will reuse them when installing the new brake pads. Pull out the brake shoe clips. Use the same needle nose pliers to remove the clips that hold the brake shoe in place. There should be two clips inside the brake system that need to be removed prior to removing the pads themselves.
If the clips are damaged, you can often purchase replacement ones at your local auto parts store. Remove the parking brake cable. The parking brake cable will be much easier to remove after the spring tension has been relieved. Pull the brake shoe set free from the backing plate. Grip the brake pads on either side and pull them directly toward you to separate them from the backing plate.
The springs will come with the brake shoe set, but the parking brake cable should remain with the vehicle. Part 3 of Place the new brake set next to the old one. Lay out the new brake pad set on a table, then place the brake shoe set you just removed from the vehicle down on the table next to it. Be sure there are no other parts on the table that can get mixed up with the components as you transfer them from the old set to the new one.
Aside from the wear on the old ones, the two sets should be identical. Swap components onto the new set. Starting with the springs, remove the components on the brake shoe set you pulled from your vehicle and place them on the new brake pads until the new pads are ready to be installed back into the vehicle.
Refer to the service manual specific to your vehicle for further guidance. Reset the parking brake adjuster. The parking brake adjuster will need to be transferred along with the springs as you transfer the hardware from the old brake set to the new one. Push the adjuster wheel away from the pin as you install it onto the new brakes. The adjuster is designed to self-adjust for your parking brake once installed.
Hold the brake spring away from the end of the cable. Use a pair of pliers or dikes to pull the parking brake spring away from the end of the cable. This will leave the end of the cable exposed to make it easier to install it back onto the brake assembly.
Place the shoe set against the backing plate and secure it. Press the brake shoe set with the new brake pads up against the backing plate, then reinstall the brake shoe clips you removed previously to hold the brake set in place. Connect the return springs. Reconnect the brake springs you disconnected in order to remove the old brakes.
If the springs become too bent or damaged in the process, they will have to be replaced. If you do, you may be able to bend it back into place using the pliers, but if not, they will need to be replaced.
You can purchase replacement springs at your local auto parts store. Reconnect the parking brake cable as well. Install the new drum. Remove the new drum from the packaging and compare it to the old drum to ensure they have the same diameter. Place the new drum over the brake shoe set and screw the axle nut on to hold it in place.
