Nissan Rear Drum Brake Repair A Comprehensive Guide

When it comes to vehicle maintenance, ensuring that your braking system is in top condition is crucial for safety and performance. For Nissan owners, rear drum brakes can be a common feature, especially in older models or specific configurations. This article will guide you through the process of repairing rear drum brakes on your Nissan, helping to save you time and possibly even money in professional repairs.

Understanding Rear Drum Brakes

Before diving into the repair process, it is essential to understand how rear drum brakes function. Unlike disc brakes, which utilize a rotor and a set of calipers, drum brakes use a cylindrical drum that rotates with the wheel. When the brake pedal is depressed, brake shoes inside the drum are forced outward against the drum itself, creating friction that slows down the vehicle. Regular maintenance and repair are necessary as wear can lead to decreased performance and safety hazards.

Signs of Damage

Knowing when to repair your rear drum brakes is crucial. Common indicators of problems include

- Unusual Noises Squeaking, grinding, or a deep rumbling sound when braking can indicate worn-out brake shoes or damaged drum components. - Vibration If you feel vibrations in the pedal or steering wheel during braking, this may be a sign of uneven wear or warping of the brake drum. - Reduced Stopping Power Any noticeable decrease in braking effectiveness should prompt immediate inspection. - Pulled to One Side If your vehicle tends to pull to one side when braking, it may indicate uneven wear or malfunctioning components.

If you experience any of these symptoms, it’s crucial to inspect your rear drum brakes without delay.

Tools and Materials Needed

Before you get started, gather the necessary tools and materials

- Jack and jack stands - Lug wrench - Socket and ratchet set - Brake drum puller (if necessary) - Brake cleaner - New brake shoes - Brake drum (if needed) - Spring tool - Gloves and safety goggles

1. Preparation Begin by parking your vehicle on a flat surface. Engage the parking brake, and use a lug wrench to loosen the wheel lug nuts slightly, but do not remove them yet.

2. Lift the Vehicle Use a jack to lift the rear end of the vehicle and secure it with jack stands. Remove the wheels by completing the removal of the lug nuts.

3. Access the Brakes Once the wheel is off, you will see the drum brake assembly. In some cases, it may be necessary to remove retaining clips or screws holding the drum in place.

4. Remove the Drum Gently pull the drum off. If it’s stuck, a brake drum puller can help; be careful not to damage the drum.

5. Inspect Components Examine the brake shoes for wear. The lining should be at least 1/8 inch thick. Inspect the drum for grooves, scoring, or warping.

6. Replace Brake Shoes If the shoes are worn, remove the old ones and take note of their configuration. Install the new shoes in the same position as the old ones, ensuring that they are secured properly and the springs are correctly positioned.

7. Reinstall the Drum Once the new shoes are in place, slide the drum back onto the axle. Make sure it spins freely without obstruction.

8. Reattach the Wheel Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle from the jack stands and then fully tighten the lug nuts in a crisscross pattern.

9. Test the Brakes Before driving, pump the brake pedal a few times to seat the new brake shoes properly against the drum.

10. Final Check Ensure everything is securely fastened and there are no leaks. Test drive the vehicle at low speeds to ensure that the brakes function correctly.

Conclusion

Repairing the rear drum brakes on your Nissan may seem daunting, but with the right tools and knowledge, the process can be straightforward. Regular maintenance and prompt repairs not only enhance your vehicle's performance but also ensure your safety on the road. If you’re ever in doubt during the repair process, don’t hesitate to consult a professional mechanic. Your safety is worth it!
