Product Details
MPA Electrical brake master cylinders are built to restore braking performance using OE sample data and controlled testing against original specifications. The NM52263 is a direct-fit hydraulic replacement for Nissan D21 and Nissan Pathfinder models listed with front disc brakes, helping maintain proper brake pressure and pedal feel. This part number, NM52263, is a practical choice for drivers servicing a worn or leaking master cylinder on these Nissan trucks and SUVs.

- External brake fluid leakage at the master cylinder

Installation Notes and Tips
Verify front disc brake configuration before installation. Bench bleeding the master cylinder before mounting helps remove trapped air and supports proper pedal feel after service. Confirm the reservoir, cap, and seal are seated correctly, and use only DOT 3 brake fluid as specified. Mounting hardware, push rod, brake booster, and pressure switch are not included.
