NISSAN D6160-51N25 Parking Brake Shoe Set

The genuine NISSAN D6160-51N25 parking brake shoe set (SHOE SET BRAKE) is a premium-quality, original part specifically engineered to ensure the reliable and safe operation of the vehicle's parking brake system. Parking brake shoes play a vital role in securing the vehicle when stationary, particularly on inclines or declines, preventing accidental vehicle rolling.

Operating Principle and Importance

Parking brake shoes are located inside the rear brake drums (or within the integrated drum section of the brake disc in combination disc brake systems). When the handbrake lever is engaged or the electronic parking brake is activated, a mechanical expander presses the shoes lined with friction material against the inner wall of the brake drum. The resulting friction locks the wheels from rotating. Because this is a safety device, worn or improperly functioning parking brake shoes pose a direct safety hazard.

Technical Features and Specifications

While exact physical dimensions depend on the specific vehicle model variant, genuine NISSAN parts feature the following general technical parameters and quality requirements:

• Material composition: High-friction coefficient, asbestos-free, heat-resistant organic or metallic friction compound for maximum grip.
• Carrier body: Precision-stamped steel frame with a corrosion-resistant coating, resistant to mechanical deformation and high tensile forces.
• Design: Manufactured to original OEM specifications, ensuring a perfect fit with return springs, expanders, and the automatic adjustment mechanism.
• Fitting position: Rear axle (left and right side, complete set for one axle).

Symptoms of Wear and Failure

Parking brake shoes are subject to natural wear and tear, especially if the handbrake is inadvertently left engaged while driving or if the brake mechanism seizes. The most common symptoms of failure include:

• Weak holding power: The vehicle starts to roll slowly on steep roads even with the parking brake engaged.
• Excessive handbrake lever travel: The handbrake lever must be pulled unusually high to achieve sufficient holding force.
• Abnormal noises: Squeaking, rubbing, or metallic sounds from the rear wheels when operating the handbrake or while driving.
• Sticking brake: After releasing the handbrake, the shoes fail to retract fully, leading to brake overheating and premature burning of the friction lining.

To ensure safe operation, regular inspection of the parking brake system is recommended, along with replacing brake shoes in pairs per axle when necessary.
