Steps to Properly Maintain and Repair Rear Drum Brake Systems

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

Rear drum brakes are a crucial component of a vehicle's braking system, providing reliable stopping power. Understanding how to properly service and maintain them can save you money and ensure your vehicle operates safely. Here's a comprehensive guide on how to do rear drum brakes.

Tools and Materials Needed

Before starting, gather the necessary tools and materials. You'll need - A jack and jack stands - A lug wrench - A brake drum puller (if necessary) - A set of drum brake shoes - Brake cleaner - A small wire brush - A torque wrench - Spring tool (for installing return springs) - Safety goggles and gloves

Step 1 Prepare Your Vehicle

Begin by parking your vehicle on a flat surface. Engage the parking brake and ensure the engine is off. Loosen the lug nuts on the rear wheels slightly, but do not remove them. Use the jack to lift the vehicle and securely position it on jack stands. Once secure, remove the lug nuts and take off the rear wheels.

Step 2 Remove the Brake Drum

Inspect the brake drum for any visible damage or wear. If it appears to be stuck, you may need to use a brake drum puller to remove it. Clean the drum and the area surrounding the brake assembly with brake cleaner to remove dirt and debris.

Step 3 Inspect the Brake Components

With the brake drum removed, check the brake shoes, springs, and hardware for wear. The shoes should have sufficient lining material; if they are worn down, they need replacing. Examine the wheel cylinder for any leaks and ensure that all components are free of rust.

Take photos of the existing installation for reference before disassembling anything. Remove the return springs from the brake shoes using a spring tool. Next, detach the shoes from the anchor points and remove the hold-down springs and clips.

Step 5 Install New Brake Shoes

Place the new brake shoes into position, ensuring they align correctly. Reattach the hold-down springs and clips first, followed by the return springs. It's essential to use the spring tool for safe installation. Afterward, double-check that the shoes are properly seated.

Step 6 Reassemble and Adjust

Once the new brake shoes are installed, check for alignment and make any necessary adjustments. Reinstall the brake drum, ensuring it spins freely. Attach the wheels and hand-tighten the lug nuts.

Step 7 Lower the Vehicle and Test

Carefully lower the vehicle from the jack stands. Once it’s on the ground, torque the lug nuts to the manufacturer's specifications. Before driving, pump the brake pedal a few times to ensure that the brake shoes seat correctly and the braking system functions well.

Conclusion

Servicing rear drum brakes may seem daunting, but with the right tools and patience, it's an achievable task for many DIY enthusiasts. Regular maintenance of your braking system is essential for vehicle safety and performance. If at any point you feel unsure, don't hesitate to consult a professional mechanic. Your safety on the road is paramount!
