Repairing the rear drum brakes on a Nissan vehicle involves understanding the mechanical intricacies and execution of precise steps to ensure optimal performance and safety. This comprehensive guide offers insights gleaned from professional expertise, blending real experience with authoritative advice, ensuring you have trustworthy recommendations for this task.

Nissan vehicles often use drum brakes on the rear wheels. These brakes are known for their durability and ability to provide strong stopping power. However, like all mechanical components, they wear over time and require maintenance or repair. The process begins with knowing when to identify issues with your rear drum brakes. Common signs include strange noises, such as grinding or squealing when braking, and a noticeable decrease in braking efficiency. If you experience these symptoms, it may be time to inspect your drum brakes for wear and damage. Before beginning the repair process, ensure you have the required tools on hand a jack, jack stands, a socket set, brake cleaner, brake spring pliers, and screwdrivers. Safety is paramount, so start by wearing safety goggles and gloves. Begin by immaculately securing the vehicle in a flat, stable area. Lift the rear with a jack, and ensure it is safely supported on jack stands before removing the wheels to provide clear access to the brake drums.

Once the wheels are off, the next step involves removing the brake drum. This can sometimes be a challenging task depending on the age and condition of the drum. If it’s stuck due to rust or debris, gently tapping around the edge with a mallet can help break any seals. In more stubborn cases, using a penetrating lubricant will assist in loosening it. Ensure not to forcefully pry the drum in a way that could damage other components. The interior of the drum will reveal several components, including the brake shoes, adjuster mechanism, and wheel cylinder. It's crucial to inspect the brake shoes for wear. If they are less than 1/8 inch thick, they should be replaced. Also, look for any fluid leaks around the wheel cylinder, which could indicate a need for replacement. Examine the hardware for rust or fatigue as these parts should be replaced collectively with the brake shoes.diagram nissan rear drum brake repair
When replacing brake shoes, ensure you handle the brake springs carefully; compression or extension can lead to potential injury. Use brake spring pliers to safely remove and install the springs. Once old shoes are removed, clean the assembly with brake cleaner to remove dust and debris. Always apply a high-temperature lubricant to the backing plate where the shoes make contact to prevent noise and ensure smooth operation. The new shoes should fit snugly, and the drum should be tested to ensure it fits over them without excessive resistance. Adjusting the self-adjuster involves turning the star wheel until the drum can fit over the shoes with slight resistance. This creates the optimal setup for the brakes to function effectively after installation. Once reassembled, the final step involves bleeding the brake system to remove any air that may have entered during the repair process. Proper bleeding ensures firm pedal feel and consistent braking performance. Recheck all connections and fittings for any potential leaks. By following these detailed instructions, the repair of Nissan rear drum brakes not only enhances your car’s braking precision but ensures you adhere to automotive safety standards. Always consult your vehicle manual for model-specific instructions and consider professional assistance if uncertain. This endeavor emphasizes the importance of recognizing signs of wear early and acting promptly. With careful attention to detail, reliance on quality tools, and adherence to procedural safety, you maintain the standard of expertise and authority synonymous with professional automotive repair.
