Repairing Nissan Rear Drum Brakes A Comprehensive Guide
When it comes to ensuring the safety and performance of your Nissan vehicle, maintaining the braking system is paramount. One of the critical components of this system is the rear drum brake, which is known for its durability and effectiveness, especially in older models. However, like any mechanical component, rear drum brakes require periodic maintenance and repair. In this article, we’ll go through the essential steps for repairing Nissan rear drum brakes.
Understanding Rear Drum Brakes
Rear drum brakes operate differently from disc brakes. Instead of using calipers and rotors, they rely on a drum that rotates with the wheel. When you press the brake pedal, brake shoes expand against the inner surface of the drum, creating friction that slows down the vehicle. Over time, these components can wear out, leading to reduced performance or complete failure.
Tools and Materials Needed
Before diving into the repair process, make sure you have the following tools and materials
- Socket set and ratchet - Screwdrivers (flathead and Phillips) - Brake cleaner - Brake pads and shoes (specific to your Nissan model) - Drum brake hardware kit - Torque wrench - Jack and jack stands - Safety goggles and gloves
Step-by-Step Repair Process
1. Preparation Begin by ensuring safety. Wear gloves and goggles to protect yourself from debris and chemicals. Park the vehicle on a flat surface and engage the parking brake.
2. Remove the Rear Wheel Use a jack to lift the rear of the vehicle and secure it with jack stands. Remove the lug nuts with a socket set and take off the rear wheel to access the drum.
3. Take Off the Brake Drum Inspect the drum for any retaining screws or clips that might be holding it in place. Remove these, and then gently pull the drum off. If it’s stuck, you may need to tap around the edges with a rubber mallet.
4. Inspect Components Once the drum is off, inspect the brake shoes, springs, and other components for wear. Look for any signs of scoring or damage on the drum itself.
5. Replace Worn Components If the brake shoes are worn down or damaged, replace them with new ones. It’s also advisable to replace the hardware kit simultaneously to ensure everything functions smoothly.
6. Clean the Drum Before reinstalling the drum, clean it thoroughly with brake cleaner. Remove any dust or debris to ensure optimal performance.
7. Reassembly Place the new or cleaned drum back on, ensuring it fits snugly. Reattach any screws or clips you removed earlier. Make sure to seat the drum properly against the wheel hub.
8. Reinstall the Wheel Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle from the jack stands and then use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
9. Test Your Brakes Once everything is reassembled, pump the brake pedal a few times to seat the shoes against the drum. Take a short drive to test the brakes, ensuring they function correctly without any noise or vibrations.
Conclusion
Repairing rear drum brakes on your Nissan can be a rewarding DIY project, saving you time and money. Regular maintenance can prevent future issues, extending the life of your braking system. Remember that if you’re unsure at any point during the process, it’s best to consult a professional mechanic to ensure your safety on the road.
