How to Change a Drum Brake

Changing a drum brake may seem like a daunting task, especially for those who are not familiar with automotive repairs. However, with the right tools, a little patience, and this step-by-step guide, you can successfully replace your drum brakes and restore your vehicle’s performance. Here’s how to do it.

Tools and Materials Needed

Before you begin, make sure you have the following tools and materials - Jack and jack stands - Lug wrench - Brake drum puller (optional but helpful) - Screwdrivers (flathead and Phillips) - Pliers - Brake cleaner - New brake shoes - Brake grease - Torque wrench - Safety goggles and gloves

Step 1 Safety First

Always prioritize safety when working on your vehicle. Make sure you wear safety goggles and gloves to protect yourself from sharp edges and chemicals.

Step 2 Lift the Vehicle

Start by parking your car on a flat, stable surface. Loosen the lug nuts slightly while the vehicle is still on the ground. Next, use a jack to lift the vehicle and secure it with jack stands. Make sure the car is stable before crawling underneath or getting too close to the wheels.

Step 3 Remove the Wheel

Once the vehicle is secured, completely remove the lug nuts and take off the wheel. This will expose the drum brake assembly.

Step 4 Remove the Drum

Inspect the drum for any retaining screws or clips. If present, remove these first. In many cases, you can just pull the drum straight off. If the drum is stuck due to rust or debris, use a brake drum puller to gently extract it.

Once the drum is removed, take a moment to inspect the brake shoes and hardware for wear. Look for cracks, significant wear, or any other damage. If any parts are worn out, they will need to be replaced.

Step 6 Remove the Old Brake Shoes

Carefully unhook the springs that hold the brake shoes in place. Use pliers to help if necessary. Take note of how the springs and shoes are arranged; you may want to take pictures for reference. Remove the old brake shoes along with any hardware.

Step 7 Install New Brake Shoes

Before installing the new brake shoes, clean the backing plate with brake cleaner to remove any dust and debris. Apply a thin layer of brake grease to the contact points to reduce noise and wear. Then, place the new brake shoes in the same position as the old ones, referring to your pictures as needed. Reattach the springs and ensure everything is secured properly.

Step 8 Reinstall the Drum

Carefully place the brake drum back onto the axle. Gently tap it if necessary to fit it snugly. If you had to remove any retaining screws, be sure to replace them as well.

Step 9 Reattach the Wheel

Position the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle off the jack stands and onto the ground. Once the vehicle is back on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 10 Test the Brakes

Before driving, pump the brake pedal several times to ensure the brake shoes are seated properly against the drum. Check for any unusual noises when you slowly drive the vehicle in a safe area. If everything feels normal, your new drum brakes are ready for use!

Conclusion

Changing drum brakes doesn’t have to be intimidating if you follow these steps carefully. Regular maintenance of your braking system is essential for safe driving, and knowing how to change drum brakes can save you both time and money in the long run. If at any point you feel uncomfortable, don’t hesitate to consult a professional mechanic. Happy wrenching!
