Understanding the Repair of Nissan Rear Drum Brakes

When it comes to vehicle maintenance, brakes are among the most crucial systems to pay attention to. Among the various types of brakes, rear drum brakes are commonly found in older vehicles and some current models, including certain Nissan vehicles. Understanding how to repair these brakes can enhance vehicle safety and prolong their lifespan.

Rear drum brakes operate differently compared to disc brakes. The primary components of a drum brake system include the drum, brake shoes, wheel cylinder, and various springs and hardware. When the brake pedal is pressed, hydraulic pressure pushes the wheel cylinders, which, in turn, forces the brake shoes against the inner surface of the drum to slow down or stop the vehicle.

Diagnosing Brake Issues

Before diving into repairs, it’s essential to diagnose the problems accurately. Common symptoms indicating potential issues with rear drum brakes include squeaking or grinding noises, a soft or spongy brake pedal, or pulling to one side when braking. If you encounter these symptoms, it might be time to inspect and possibly repair the drum brakes.

Tools Required

To perform a rear drum brake repair on your Nissan, you'll need a few essential tools

1. A jack and jack stands for lifting the vehicle. 2. A lug wrench to remove the wheel. 3. A brake drum puller (if necessary). 4. Basic hand tools such as pliers, wrenches, and screwdrivers. 5. A brake cleaner, new brake shoes, and any other necessary replacement parts.

1. Preparation Begin by parking the vehicle on a flat surface, turning off the ignition, and engaging the parking brake. Loosen the lug nuts on the rear wheels before jacking up the vehicle and removing the wheels.

2. Removing the Drum Once the wheel is off, inspect the drum for any retaining screws. Remove them and gently pull the drum off. If the drum is stuck, a brake drum puller can help.

3. Inspecting Components Examine the brake shoes for wear. If they are worn down to the minimum thickness, replace them. Check the wheel cylinder for leaks, and inspect the springs and hardware for any signs of damage or wear.

4. Installation of New Parts If replacement is necessary, install the new brake shoes, ensuring they are positioned correctly. Reinstall any springs and hardware, making sure everything is secured.

5. Reattach the Drum Once all components are replaced or reassembled, reattach the brake drum. Ensure that it spins freely without any obstruction.

6. Testing Reinstall the wheel and lower the vehicle. Before hitting the road, pump the brake pedal a few times to seat the brake shoes against the drum. Test the brakes gradually at low speeds in a safe area.

Conclusion

Repairing Nissan rear drum brakes can be a manageable task with the right tools and knowledge. By maintaining your vehicle’s brake system properly, you not only enhance your safety but also boost the overall performance of your car. Always remember to consult your vehicle's manual for specific instructions and guidelines related to your particular model.
