Steps to Repair and Adjust Rear Drum Brake System Effectively

How to Fix Rear Drum Brakes A Step-by-Step Guide

Rear drum brakes are a common braking system found in many vehicles, particularly older models. While they are effective at providing stopping power, they can sometimes develop issues that require attention. If you're experiencing problems with your rear drum brakes, don’t worry! With this step-by-step guide, you'll learn how to diagnose and fix common issues associated with rear drum brakes.

Step 1 Gather Necessary Tools and Supplies

Before starting any repair work, it's essential to gather all necessary tools and supplies. You will typically need - A jack and jack stands - Lug wrench - Drum brake spring tool - Screwdriver - Pliers - Brake cleaner - New brake shoes (if needed) - Brake hardware kit (springs and clips) - Safety goggles and gloves

Step 2 Safety First

Safety should always be your top priority. Ensure that the vehicle is on a flat surface, and engage the parking brake. Use the jack to lift the vehicle, and secure it with jack stands. Never rely solely on the jack for support.

Step 3 Remove the Rear Wheel

Using the lug wrench, loosen the lug nuts of the rear wheel you’ll be working on. Remove the wheel to gain access to the drum brake assembly. It’s a good practice to place the lug nuts somewhere safe so you don’t misplace them.

Step 4 Inspect the Brake Drum

Before proceeding with any repairs, visually inspect the brake drum for any signs of wear or damage. Look for grooves, cracks, or excessive rust. If the drum is damaged, you may need to replace it. If it seems in acceptable condition, you can proceed to remove it.

Step 5 Remove the Brake Drum

To remove the brake drum, you may need to gently tap it with a hammer if it is stuck. Be cautious not to damage the surrounding components. After the drum comes loose, slide it off the wheel hub.

Step 6 Disassemble the Brake Components

Once the drum is removed, take note of how the brake shoes and springs are arranged. It can be helpful to take a picture for reference. Carefully remove the brake shoes, springs, and any other hardware using the brake spring tool and pliers. Be cautious, as springs can be under tension and may snap back.

Step 7 Clean and Inspect Components

Clean the brake components with brake cleaner. Remove any dust or debris that may have accumulated. Inspect all parts for wear and damage. If the brake shoes are worn down, it’s time to replace them. Install a new brake hardware kit if necessary.

Step 8 Install New Brake Shoes

Begin installing the new brake shoes by attaching them to the anchor and adjusting them as per your reference picture. Make sure to install the springs and keepers securely. Pay attention to the orientation of each component; incorrect installation can lead to brake failure.

Step 9 Reassemble the Brake Drum

Once the new brake shoes are securely in place, slide the brake drum back onto the hub. Make sure it spins freely and doesn’t catch on any components.

Step 10 Reinstall the Wheel and Lower the Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts to hold it in place. Lower the vehicle from the jack stands and then tighten the lug nuts fully in a criss-cross pattern to ensure even pressure.

Step 11 Test the Brakes

Before taking the vehicle out on the road, pump the brake pedal a few times. This helps seat the brake shoes against the drum. Take a short test drive to ensure that the brakes are functioning correctly.

Conclusion

Fixing rear drum brakes can be a straightforward process if you follow the right steps. By maintaining your brakes, you’ll enhance the safety and performance of your vehicle. If you’re unsure about any aspect of the repair, don’t hesitate to consult a professional for assistance. Proper brake maintenance is key to safe driving.
