Product Details

MPA Electrical NM55649 is engineered as a brake master cylinder replacement for Nissan Titan trucks equipped with front disc brakes. The unit is tested against OE specifications using controlled inspection processes and sample-based validation to help deliver consistent hydraulic performance after installation. The 2-hole mounting design, 0.354 in. mounting hole diameter, and aluminum master cylinder body support a straightforward replacement for worn or leaking original components. The reservoir is included, along with the cap, while the brake booster, push rod, seals, mounting hardware, sensor, and brake pressure switch are not included.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. MPA Electrical NM55649 is a direct-fit service part for 2008-2010 Nissan Titan models with front disc brakes, and it is built to restore hydraulic pressure in the brake system.

What It Helps Fix

• Low or sinking brake pedal feel
• Brake fluid leakage from the master cylinder body
• Uneven or delayed hydraulic brake response
• Loss of braking performance caused by internal seal wear
• Brake warning symptoms related to master cylinder failure

Installation Notes

Before installation, verify the vehicle is a 2008-2010 Nissan Titan with front disc brakes and confirm bore size, mounting pattern, and fluid requirements. Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic circuit. Use clean DOT 3 brake fluid and inspect the brake lines, booster interface, and reservoir connections for wear or contamination during service.

Quality Assurance

MPA Electrical tests each master cylinder against OE specifications using proprietary processes and strict protocols to support consistent braking performance out of the box. The NM55649 is a new standard replacement part built for brake hydraulic service on the Nissan Titan platform.
