replacing shoes on drum brakes

Replacing shoes on drum brakes is a crucial maintenance task that ensures your vehicle operates safely and efficiently. Drum brakes are a common braking system found on many older vehicles and some modern models, especially in the rear. Understanding how to replace brake shoes can save you time and money, and it’s a skill that many car enthusiasts and DIY mechanics value.

First, gather the necessary tools a car jack, jack stands, a lug wrench, a brake spring tool, a hammer, and of course, new brake shoes. It’s also advisable to have a brake cleaner spray and some grease for lubrication.

The first step is to ensure safety. Park your vehicle on a flat surface, engage the parking brake, and wear safety glasses. Use the lug wrench to loosen the lug nuts on the wheel where you will be replacing the brake shoes. Once loose, lift the vehicle with the jack and secure it with jack stands. Remove the wheel to access the drum brake assembly.

With the wheel off, inspect the brake drum. If it’s damaged or excessively worn, consider replacing it. Remove the drum by pulling it straight off; you may need to tap it gently with a hammer if it’s stuck. Once exposed, take note of the current configuration of the brake shoes and associated hardware, as this will aid reassembly.

To replace the shoes, you will need to detach them from the backing plate. Start by removing the return springs, which can be challenging; a brake spring tool will help. As you remove the old shoes, take care to keep any small parts or clips for reuse unless your new shoes come with these components.

Next, install the new brake shoes. Begin with the primary shoe, which is typically shorter, followed by the secondary shoe. Ensure that all springs and clips are properly attached to hold the shoes in place. Grease the pivot points to facilitate smooth operation.

Once the new shoes are installed, carefully replace the drum, ensuring it smoothly rotates without binding. Reattach the wheel and hand-tighten the lug nuts before lowering the vehicle back to the ground. Finally, fully tighten the lug nuts in a crisscross pattern to ensure even pressure.

Remember to pump the brake pedal a few times to seat the new shoes before driving. After replacing brake shoes, test the brakes at low speeds in a safe area to ensure they are functioning correctly. Regular maintenance of your drum brakes can help prolong their lifespan and enhance your vehicle's safety.
