Replacing Rear Drum Brakes A Comprehensive Guide
When it comes to maintaining your vehicle, one of the most crucial components to consider is the braking system. While many modern cars have transitioned to disc brakes, numerous older and budget-friendly vehicles still utilize rear drum brakes. Understanding how to replace rear drum brakes is essential for both your safety and the longevity of your vehicle. This guide will walk you through the steps of replacing rear drum brakes, ensuring you have the knowledge you need to tackle the job confidently.
Tools and Materials Needed
Before starting the replacement process, gather all necessary tools and materials. You will need
- New drum brake shoes - Brake drums (if they are worn) - Brake cleaner - Wrenches and socket set - Screwdrivers - Pliers - A jack and jack stands - A brake spring tool (optional but recommended) - Safety goggles and gloves
Safety First
Before you begin, prioritize safety. Make sure your vehicle is parked on a flat surface, engage the parking brake, and wear safety goggles and gloves to protect yourself from dust and debris.
Step 1 Remove the Wheel
Start by loosening the lug nuts on the rear wheel using a wrench or socket. Once the lug nuts are slightly loosened, use a jack to lift the vehicle off the ground. Place jack stands under the vehicle for added safety. Completely remove the lug nuts and take off the wheel to access the drum brake assembly.
Step 2 Inspect the Brake Components
With the wheel removed, examine the brake drum and shoes for wear. Look for signs of cracking, pitting, or excessive wear on the brake drum. If the drum is damaged or worn beyond the manufacturer's specifications, it should be replaced. Check the brake shoes for wear as well; if they have less than 1/8 inch of shoe material, it’s time for a replacement.
Step 3 Remove the Brake Drum
To assess the brake shoes, you’ll need to remove the drum. This can often involve a slight pulling motion, but if the drum is stuck due to rust or wear, you may need to tap it gently with a hammer. If there are retaining screws, remove them first. Once the drum is free, slide it off the wheel hub to reveal the brake shoes.
Step 4 Disassemble the Brake Assembly
Carefully take note of how the existing components are assembled, as you will need to replicate this during reassembly. Start by removing the retaining springs, which hold the brake shoes in place. Use a brake spring tool or pliers to gently detach these springs. Once removed, you can take out the old brake shoes.
Step 5 Install New Brake Shoes
Before installing the new shoes, clean the backing plate with brake cleaner to remove any dust or debris. Position the new brake shoes where the old ones were, aligning them properly. Reattach the retaining hardware and springs, ensuring everything is secured tightly. It’s crucial to make sure the shoes are not pinched and can move freely as the brakes are applied.
Step 6 Replace the Brake Drum
Once the new shoes are in place, it’s time to reinstall the brake drum. Slide the drum back onto the wheel hub, ensuring it fits snugly over the new shoes. If the drum feels tight, check if the shoes are properly aligned or adjusted.
Step 7 Reassemble the Wheel
With the drum in place, it’s time to put the wheel back on. Place it over the hub and hand-tighten the lug nuts. Lower the vehicle off the jack stands, and once it’s securely on the ground, tighten the lug nuts in a crisscross pattern to ensure even distribution.
Step 8 Test the Brakes
Before taking your car for a drive, pump the brakes a few times to seat the new shoes against the drum. This step is crucial, as it allows the brake shoes to adjust to their new position. After this, perform a short test drive at low speeds to ensure everything is functioning correctly.
Conclusion
Replacing rear drum brakes may seem daunting, but with the right tools and a bit of patience, it can be a straightforward task. Regular maintenance of your braking system not only improves your vehicle's performance but also enhances safety while driving. If you ever feel uncertain, don’t hesitate to consult with a professional mechanic to ensure your car remains in peak condition. Happy driving!
