How to Replace Rear Brake Drums

Replacing rear brake drums may seem like a daunting task, but with the right tools and some basic knowledge, it can be a manageable and rewarding project. Brake drums are crucial components of a vehicle’s braking system, and over time, they can wear out or become damaged. Here’s a step-by-step guide on how to replace rear brake drums effectively.

Tools and Materials Required

Before starting, ensure you have the following tools and materials - Jack and jack stands – to lift and secure the vehicle - Lug wrench – for removing the wheel bolts - Brake drum puller – if the drums are stubborn - Replacement brake drums – specific to your vehicle's make and model - Brake shoes (recommended) – if you’re replacing the drums, consider replacing the shoes as well - C-clamp – to compress the brake cylinder - Brake cleaner – for cleaning parts - Lint-free cloths – for cleaning and wiping surfaces - Torque wrench – to ensure proper tightness of lug nuts - Safety glasses and gloves – to protect yourself during the process

Step-by-Step Instructions

Step 1 Safety First

Begin by ensuring safety. Park your vehicle on a flat surface, engage the parking brake, and wear safety glasses and gloves. It’s crucial to take proper precautions when working with brake components.

Step 2 Lift the Vehicle

Using the jack, lift the rear of the vehicle. Once elevated, place jack stands underneath the rear frame to secure the vehicle in place. Never attempt to work on a vehicle that is only supported by a jack.

Step 3 Remove the Wheels

Using the lug wrench, loosen and remove the lug nuts. Take off the rear wheels to access the brake drums.

Step 4 Inspect the Brake Components

Inspect the brake system while the wheels are off. Look for signs of wear on the brake shoes and check the condition of the brake springs and other components. If the brake shoes are worn down, it’s advisable to replace them simultaneously with the drums.

Step 5 Remove the Brake Drums

The brake drums may be secured with retaining screws; if so, remove them. If the drums are stuck due to corrosion or wear, use a brake drum puller. Position the puller on the drum and turn the handle until the drum loosens. Gently slide the drum off the wheel hub.

Step 6 Clean the Brake Assembly

Before installing the new drum, clean the brake assembly with brake cleaner. Remove any dirt, grease, or debris from the surface. This step is vital for ensuring optimal performance of the new components.

Step 7 Install New Brake Drums

Position the new brake drum onto the wheel hub. Ensure it is seated properly and rotates freely. If you’re replacing brake shoes, follow the manufacturer’s instructions for installation. Remember to compress the brake cylinder using a C-clamp if necessary.

Step 8 Reattach the Wheels

Place the wheels back onto the hub, hand-tighten the lug nuts, and lower the vehicle from the jack stands using the jack. Once the vehicle is on the ground, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications to ensure they are secure.

Step 9 Test the Brakes

Before hitting the road, pump the brake pedal a few times to seat the new drums and shoes. It’s crucial to ensure that the braking system is functioning correctly. Test the brakes gently at low speed in a safe area.

Conclusion

Replacing rear brake drums is an essential maintenance task that can save you money and ensure the safety and performance of your vehicle. By following these steps and taking the necessary precautions, you can complete the job successfully. Regular brake maintenance not only extends the life of your vehicle but also contributes to a safer driving experience. Always consult your vehicle’s service manual for specific instructions related to your make and model, and when in doubt, seek the help of a professional mechanic.
