How Hard Is It to Change Drum Brakes?

Changing drum brakes might seem like a daunting task for those not well-versed in automotive repair. However, with the right tools, some basic mechanical knowledge, and a bit of patience, it can be a manageable project for many car enthusiasts. In this article, we will explore the complexity of changing drum brakes, the necessary tools, and the steps involved in the process.

Understanding Drum Brakes

Drum brakes consist of a cylindrical drum that rotates with the wheel and brake shoes that are pressed against the drum to create friction and slow down the vehicle. Over time, brake shoes wear out and need replacement. Additionally, the brake drum may become warped or damaged, necessitating its replacement as well.

Tools Needed

Before starting, it’s essential to gather the right tools. The following are typically required for changing drum brakes

1. Jack and Jack Stands To lift the vehicle safely. 2. Lug Wrench For removing the wheel nuts. 3. Brake Spring Tool To remove and install the springs. 4. Socket Set For various bolts. 5. Pliers To assist in removing clips and springs. 6. Brake Cleaner For cleaning components. 7. Replacement Brake Shoes New shoes are essential for effective braking. 8. New Drum (if necessary) If the existing drum is damaged or worn beyond specification.

The Process

1. Preparation Start by ensuring the vehicle is parked on a level surface. Engage the parking brake for added safety. Loosen the lug nuts on the rear wheel where you will be changing the brakes, but do not remove them yet.

2. Lifting the Vehicle Use a jack to lift the vehicle and place jack stands underneath for safety. Remove the lug nuts completely and take off the wheel.

3. Removing the Brake Drum Inspect the drum for retaining screws or clips. If there are screws, remove them. Sometimes, the drum may be stuck due to rust; tapping it gently with a hammer can help loosen it.

4. Inspecting Components Once the drum is off, check the condition of the brake shoes, hardware, and drum. If the shoes are worn down or the drum is badly scored or warped, you’ll need to replace them.

5. Removing Old Brake Shoes Use your brake spring tool to carefully remove the springs and then detach the brake shoes. Pay attention to how everything is assembled, as you will need to replicate this when installing the new shoes.

6. Installing New Brake Shoes Position the new brake shoes in the same configuration as the old ones. Reattach the springs and ensure everything is tight and secure.

7. Reinstalling the Brake Drum After the new shoes are secured, slide the brake drum back onto the wheel hub. If you replaced the drum, ensure it is correctly seated.

8. Reassembling Put the wheel back on, hand-tighten the lug nuts, lower the vehicle off the jack stands, and then completely tighten the lug nuts in a crisscross pattern to ensure even tightening.

9. Testing Before driving, pump the brake pedal a few times to seat the new shoes against the drum. Check for any unusual noises during your test drive.

Conclusion

Changing drum brakes isn’t as difficult as it may seem. With the right tools and steps, many car owners can perform this task themselves, potentially saving money on labor costs. However, if you are ever unsure about the process or if the braking system feels compromised, it’s always best to consult with a professional mechanic. Proper braking function is crucial for vehicle safety, so make sure you approach this job with care and attention.
