Product Details

MPA Electrical NM52780 is engineered as a brake master cylinder replacement for the 2001 Nissan Pathfinder. It is built to restore hydraulic braking performance by matching OE specifications through tested manufacturing processes and controlled inspection standards. This unit includes the reservoir, cap, and seal, while omitting the brake booster, push rod, sensor, and mounting hardware.

The NM52780 is a practical choice for a Nissan Pathfinder brake master cylinder replacement when the original unit shows internal leakage, poor pedal feel, or inconsistent brake pressure. Its 1-inch bore and aluminum construction support a direct-fit service repair for the Pathfinder brake hydraulics system.

Common Brake Issues It Can Address

• Low or sinking brake pedal
• Brake fluid bypass inside the master cylinder
• Uneven or delayed hydraulic pressure
• External fluid seepage at the master cylinder
• Reduced braking response in the hydraulic system

Installation Notes and Tips

Before installation, confirm the vehicle is a 2001 Nissan Pathfinder with front disc brakes and verify bore size and mounting points against the original part. Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic circuit. Use DOT 3 brake fluid only, and inspect brake lines, fittings, and the booster interface for wear or contamination during service.

Quality Assurance

MPA Electrical uses OE sample references and testing protocols to verify master cylinder performance against original specifications. Part number NM52780 is a new standard replacement brake master cylinder for the 2001 Nissan Pathfinder, built for consistent braking performance after installation.
