How to Install Self-Adjusting Drum Brakes

Installing self-adjusting drum brakes is a vital skill for many DIY enthusiasts and car owners. These brakes are crucial for ensuring your vehicle stops effectively and safely. This article aims to guide you through the entire process step by step, providing tips to make the installation as smooth as possible.

Tools and Materials Needed

Before starting, gather the necessary tools and materials. You will need

1. A jack and jack stands 2. Lug wrench 3. Screwdrivers (flathead and Phillips) 4. Pliers 5. Brake cleaner 6. Drum brake kit (including shoes and hardware) 7. Torque wrench 8. Safety goggles and gloves

Safety First

Always prioritize safety when working on your vehicle. Ensure the car is parked on a level surface, engage the parking brake, and wear safety goggles and gloves throughout the process.

Step 1 Preparing the Vehicle

Begin by loosening the lug nuts on the wheel where you will be working. Do not remove them completely at this stage. Next, use the jack to lift the vehicle and secure it on jack stands for safety. Once the car is securely elevated, remove the lug nuts and take off the wheel.

Step 2 Removing the Drum

Inspect the drum brakes. Locate the brake drum and inspect for any retaining screws or clips that may be holding it in place. Remove these using the appropriate tools. Gently pull the drum off; if it’s stuck, you may need to tap it lightly with a hammer.

Step 3 Inspecting Existing Brakes

Once removed, inspect the existing brake shoes and components for wear and damage. Check the springs, adjuster, and other hardware. If they show significant wear, consider replacing them along with the shoes.

Step 4 Installing New Shoes

Now it’s time to install the self-adjusting shoes. Begin by comparing the new brake shoes to the old ones to ensure proper sizing. Install the new brake shoes into the drum assembly. Make sure the self-adjusting lever and mechanism are positioned correctly, usually at the top of the assembly.

Step 5 Installing Hardware

Install the new hardware included in your brake kit. This typically consists of several springs and clips that secure the brake shoes in place. Refer to a service manual or online resource specific to your vehicle for the correct installation of these components. Ensure that everything is tight but not overly strained to avoid premature failure.

Step 6 Adjusting the Brakes

After installing the shoes and hardware, you need to adjust the brakes properly. Most self-adjusting drum brakes have a mechanism that will take care of this automatically. However, rotate the adjusting wheel using a screwdriver or a specified tool until the shoes lightly contact the drum. This ensures that the brakes are set correctly for optimal performance.

Step 7 Replacing the Drum

Once the shoes are installed and adjusted, replace the drum by sliding it back onto the wheel assembly. Ensure it rotates freely without excessive friction on the brake shoes.

Step 8 Reattaching the Wheel

Now, you can reattach the wheel. Position it back on the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground before securing the lug nuts in a crisscross pattern with a torque wrench to the manufacturer’s specifications.

Step 9 Testing

Before hitting the road, it's critical to test your new brake installation. Start the vehicle and pump the brakes a few times to ensure that they engage smoothly. Drive slowly in a safe environment to confirm that everything feels right before hitting the highway.

Final Thoughts

Installing self-adjusting drum brakes can seem daunting, but with the right tools and a methodical approach, it can be completed by most car enthusiasts. Always consult your vehicle’s manual for specific instructions and specifications. Regular maintenance of your braking system is essential for safe driving, so be sure to check your brakes periodically even after installation. Happy driving!
