Installing Drum Brakes A Step-by-Step Guide

Drum brakes are a common type of braking system found in many vehicles, especially older models and trucks. While disc brakes have become increasingly popular due to their superior performance and heat dissipation, drum brakes remain widely used for their simplicity and effectiveness. If your vehicle is equipped with drum brakes and you’re looking to maintain or replace them, this guide provides a comprehensive overview of the installation process.

Tools and Materials Required

Before you begin, it’s essential to gather the necessary tools and materials. You’ll need

1. New brake shoes 2. Brake drums 3. Brake fluid 4. Wrenches and sockets 5. Screwdrivers 6. Brake spring tool 7. Pliers 8. Jack and jack stands 9. Brake cleaner 10. Safety glasses

Safety First

Safety is paramount when working on your vehicle. Ensure you are wearing safety glasses to protect your eyes from any debris. When lifting the vehicle, use jack stands to secure it and prevent any accidents.

Step 1 Prepare the Vehicle

Start by parking the vehicle on a level surface and engaging the parking brake. Loosen the lug nuts on the wheel where you will be working, but do not remove them yet. Use a jack to lift the vehicle and secure it with jack stands. Once stable, remove the lug nuts and the wheel.

Step 2 Remove the Drum

With the wheel removed, you will see the drum brake assembly. To take off the drum, inspect for any retaining screws or clips that might be holding it in place. If the drum is stuck due to corrosion or debris, gently tap it with a mallet to free it. Carefully pull the drum off the wheel hub.

Take a moment to examine the components of the drum brake system. Look for wear on the brake shoes, springs, and the drum itself. If any components appear damaged or excessively worn, they should be replaced. A brake cleaner can be used to remove any dust or debris for better visibility.

Step 4 Remove Old Brake Shoes

To remove the old brake shoes, you will need to detach the springs and retainers. Use a brake spring tool for this step, as the springs can be under significant tension. Start by removing the return springs, then unhook the adjuster. Take note of how everything is assembled, as you will need to replicate this when you install the new components.

Step 5 Install New Brake Shoes

Now it’s time to install the new brake shoes. Start by attaching the new shoes to the backing plate in the same order as the old ones. Be sure to connect the adjuster and the return springs securely. It’s crucial to ensure that everything is fitted correctly to prevent any issues when the brakes are applied.

Step 6 Reattach the Drum

Once the new shoes are in place, you can reattach the brake drum. Align it carefully over the shoes and gently press it into place. If necessary, spin the drum to ensure it moves freely without binding.

Step 7 Reassemble the Wheel

With the drum reattached, it’s time to put the wheel back on. Place the wheel onto the hub and hand-tighten the lug nuts. Lower the vehicle from the jack stands and then tighten the lug nuts to the manufacturer’s specifications.

Step 8 Test the Brakes

Before you hit the road, it’s crucial to test the brakes. Pump the brake pedal a few times to seat the brake shoes against the drum. After adjusting the brake shoes, check for correct brake function by gently rolling the vehicle forward and applying the brakes. Listen for any unusual noises and check for any signs of malfunction.

Conclusion

Installing drum brakes can be a manageable task for those with some mechanical aptitude. By following this step-by-step guide, you can save on labor costs while ensuring your vehicle has a well-functioning braking system. Remember to always prioritize safety and consult your vehicle’s manual for specific instructions related to your model. Happy wrenching!
