A Comprehensive Guide to Nissan Rear Drum Brake Repair

When it comes to vehicle maintenance, ensuring your braking system is in optimal condition is paramount for safety. For Nissan vehicles equipped with rear drum brakes, regular check-ups and repairs are essential to maintain stopping power and prevent costly damage. This guide will walk you through the basic concepts of rear drum brake repair, including identification of problems, the necessary tools, and step-by-step instructions for performing repairs.

Understanding Rear Drum Brakes

Rear drum brakes consist of a cylindrical drum, brake shoes, and a hydraulic system that activates the shoes against the drum to create friction and slow down the vehicle. Over time, components can wear out, leading to decreased performance and safety risks. Common issues include worn-out brake shoes, leaking wheel cylinders, or a malfunctioning adjustment system.

Identifying Problems

Before jumping into repairs, it’s crucial to identify any braking issues. Key indicators that your rear drum brakes may need attention include

1. Squeaking or Grinding Noises These sounds often signify worn brake shoes or metal-on-metal contact. 2. Poor Braking Performance If you notice longer stopping distances or a spongy brake pedal, it could indicate hydraulic issues.

3. Pulling to One Side This may suggest uneven wear or a malfunction within the brake system.

4. Leaking Brake Fluid A visible leak near the brake components can indicate a faulty wheel cylinder or brake line.

Tools Required

Before beginning the repair process, gather the necessary tools

- Jack and jack stands - Lug wrench - Brake drum puller - Screwdrivers (flat and Phillips) - Pliers - Brake cleaner - New brake shoes (if necessary) - Replacement wheel cylinders (if applicable) - Torque wrench

Step-by-Step Repair Process

Follow these steps to perform rear drum brake repairs on your Nissan

1. Preparation - Park your vehicle on a flat surface and ensure it is in gear or has the parking brake engaged. - Loosen the lug nuts on the rear wheels but do not remove them yet.

2. Lifting the Vehicle - Use a jack to lift the rear of the vehicle and place jack stands for added safety. Remove the lug nuts and take off the wheels.

3. Removing the Brake Drums - Inspect the drums for wear and determine if they need to be turned or replaced. - If the drums are stuck, use a brake drum puller to remove them carefully.

4. Inspecting Components - Check the brake shoes for wear. Replace them if the lining is less than 1/8 inch. - Examine the wheel cylinder for leaks. If it’s leaking, it will need replacement.

5. Installing New Brake Shoes - Remove the old brake shoes by detaching the springs and clips. - Install the new brake shoes, ensuring they are securely attached to their respective anchor points.

6. Reassemble the Brake Assembly - Reinstall the brake drum, ensuring that it spins freely. - Adjust the shoes to make contact with the drum without dragging.

7. Reattaching the Wheels - Place the wheels back on, hand-tighten the lug nuts, and lower the vehicle. Finally, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.

8. Testing the Brakes - Before driving, pump the brake pedal to ensure the brake shoes are seated correctly. Test drive your vehicle in a safe area to verify the brakes are functioning properly.
