Detailed Description

The NM52585 brake master cylinder is engineered for Nissan Pathfinder models equipped with front disc brakes from 1991 through 1995. It is built as a standard replacement hydraulic component with a 1-inch bore, aluminum housing, and an included reservoir to support proper brake fluid delivery. The cap and seal are included, while the brake booster, push rod, sensor, pressure switch, mounting hardware, and bracket are not included.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are searching for a Nissan Pathfinder brake master cylinder, NM52585 provides a direct-fit service option for restoring hydraulic pressure and pedal feel on the specified front disc brake configuration.

What It Helps Address

• Low or inconsistent brake pedal pressure
• Internal master cylinder seal wear
• Brake fluid leakage at the master cylinder
• Reduced braking response from hydraulic loss
• Brake system service needs on a 1991-1995 Nissan Pathfinder

Installation Notes and Tips

Before installation, confirm the vehicle is a 1991-1995 Nissan Pathfinder with front disc brakes and verify the bore size and mounting pattern match the original unit. Bench bleed the master cylinder before connecting brake lines, and use DOT 3 brake fluid only. Inspect the brake booster, lines, and fittings for wear or contamination during service, since related hydraulic issues can affect pedal performance.

Quality Assurance

MPA Electrical tests each unit against OE specifications using proprietary processes and strict protocols to support consistent braking performance out of the box. Part number NM52585 is supplied as a new replacement brake master cylinder for the listed Nissan Pathfinder applications.
