How to Install Self-Adjusting Drum Brakes

Drum brakes are a vital part of your vehicle's braking system, providing reliable stopping power. Among the different types of drum brakes, self-adjusting ones are particularly convenient as they automatically adjust themselves to maintain the proper brake shoe clearance. Installing self-adjusting drum brakes can be a straightforward task if you follow the correct steps. Here’s a step-by-step guide to help you through the process.

Tools and Materials Needed Before you begin, ensure you have the following tools and materials - Jack and jack stands - Lug wrench - Brake cleaner - New brake shoes (self-adjusting) - Brake drum - Brake spring tool (optional but helpful) - Torque wrench - Safety gloves and goggles

Step 1 Preparation Start by parking your vehicle on a flat surface and engaging the parking brake. Gather all your tools and materials before you begin. Wear your safety gloves and goggles to protect yourself during the installation process.

Step 2 Remove the Wheel Using a lug wrench, loosen the lug nuts slightly while the wheel is still on the ground. Once you've done this, lift the vehicle using the jack and support it securely with jack stands. Now, remove the lug nuts completely and take off the wheel to access the drum brake assembly.

Step 3 Remove the Brake Drum With the wheel off, locate the brake drum. If it's stuck, gently tap around the drum with a rubber mallet. Once loose, pull the drum straight off the hub. Inspect the inside of the drum for wear or scoring; if it's excessively worn, consider replacing it.

Step 4 Take Note of the Old System Before removing any components, take a picture or make a diagram of how the old brake system is assembled

Step 5 Remove the Old Brake Shoes Release the tension on the brake springs carefully. Depending on your brake system, this may involve removing hold-down springs and retaining clips. Once the tension is released, remove the old brake shoes. Be cautious, as the springs can snap back and cause injury.

Step 6 Install the New Self-Adjusting Brake Shoes Take your new self-adjusting brake shoes and begin by positioning them in the same configuration as your old shoes. The actual adjustment mechanism should face the correct direction, as indicated in the installation instructions included with your new shoes. Secure the shoes to the backing plate with the appropriate hold-down springs and retaining clips.

Step 7 Set Up the Self-Adjusting Mechanism Ensure that the self-adjusting mechanism is properly set up. This typically involves ensuring that the adjustment wheel (or lever) is engaged correctly. You may need to spin the wheel to engage the brake shoes to the drum slightly, allowing the shoes to align properly.

Step 8 Reinstall the Brake Drum Once the new shoes are in position, carefully place the brake drum back over the shoes. Make sure it slides on easily; it should not bind or grind as it turns.

Step 9 Replace the Wheel Reinstall the wheel and hand-tighten the lug nuts. Lower the vehicle back to the ground using the jack and then torque the lug nuts to the manufacturer's specifications.

Step 10 Test the Brakes Before driving, pump the brake pedal several times to position the brake shoes appropriately against the drum. Take your vehicle for a slow test drive to ensure everything is working correctly.

Conclusion Installing self-adjusting drum brakes may seem daunting, but with the right tools and careful attention to detail, it can be a satisfying project. Regular maintenance and timely replacement of worn parts will enhance your vehicle's performance and safety. Always consult your vehicle's manual or seek professional assistance if you're unsure at any stage of the process.
