How to Do Rear Drum Brakes A Comprehensive Guide
Rear drum brakes are a crucial component of many vehicles, playing an essential role in the overall braking system. Unlike disc brakes, which are becoming increasingly common, drum brakes are still widely used, particularly in older vehicles and light-duty trucks. Understanding how to inspect, maintain, and replace rear drum brakes is an important skill for any car enthusiast or owner. This guide will walk you through the steps to achieve this effectively.
1. Safety First
Before you start any work on your vehicle, safety should be your top priority. Ensure you have the necessary tools at hand, including a jack, jack stands, wrenches, and a brake spring tool. It’s also wise to wear safety goggles and gloves to protect yourself from dust and debris.
2. Raise the Vehicle
Begin by loosening the lug nuts on the rear wheels before lifting the vehicle. After that, use a jack to raise the car and secure it with jack stands. Always ensure that the vehicle is stable before crawling underneath or applying any force.
3. Remove the Wheel
Once the vehicle is securely elevated, remove the lug nuts completely and take the rear wheel off. Keep the lug nuts in a safe place, as you will need them again for reassembly.
4. Inspect the Brake Assembly
With the wheel removed, you'll have clear access to the rear drum brake assembly. Inspect the drum for any visible wear and tear. Look for grooves or excessive scoring, which can indicate that the drum needs to be resurfaced or replaced.
To remove the brake drum, locate and remove the screws (if applicable) and gently pull the drum off the wheel hub. If the drum is stuck, you may need to tap it lightly with a hammer or use a brake drum puller. Be cautious not to damage the assembly.
6. Examine the Brake Shoes and Hardware
With the drum removed, take a close look at the brake shoes. They should have a sufficient amount of friction material—usually about a quarter-inch thick. If they appear worn down to the metal or are unevenly worn, it’s time to replace them. Also, inspect the hardware such as springs and clips for any signs of wear or corrosion.
7. Replace the Brake Shoes
If you determine that replacement is necessary, start by disconnecting the springs using a brake spring tool. Remove the worn brake shoes and carefully install the new ones. Make sure to follow the manufacturer’s instructions for your specific model, as the configuration may vary.
8. Reassemble the Drum Brake
After installing the new brake shoes, carefully reattach the brake drum. Make sure it spins freely without any binding. If it feels too tight, you may need to adjust the-star wheel adjuster to ensure a proper fit.
9. Reinstall the Wheel
Once the brake drum is securely in place, it’s time to reattach the wheel. Align the bolt holes and hand-tighten the lug nuts. Lower the vehicle and then tighten the lug nuts in a crisscross pattern to ensure even pressure.
10. Final Checks
Before taking your vehicle for a test drive, pump the brake pedal several times to set the shoes against the drum. Check for any unusual noises or sensations while testing the brakes at low speeds.
Conclusion
Maintaining your rear drum brakes is an essential aspect of vehicle ownership that can save you money and ensure safety on the road. Regular inspections and timely replacements can keep your braking system functioning effectively. If you are ever unsure, don’t hesitate to seek professional assistance to avoid potential pitfalls. With the right knowledge and tools, performing rear drum brake maintenance can be a rewarding experience.
