Detailed Description

MPA Electrical M55319 is a brake master cylinder engineered for 2003-2008 Nissan Murano applications with front disc brakes. As a remanufactured hydraulic component, it is built to restore brake system pressure and pedal feel while matching OE specifications for bore size, mounting layout, and fluid compatibility.

Common Problems This Part Can Address

• Low or sinking brake pedal
• Brake fluid leakage at the master cylinder
• Uneven or inconsistent hydraulic brake pressure
• Soft pedal response after master cylinder wear
• Brake warning symptoms related to hydraulic loss

Installation Notes and Tips

Verify the vehicle is a 2003-2008 Nissan Murano with front disc brakes before installation. This master cylinder does not include the reservoir, cap, booster, push rod, sensor, brake pressure switch, or mounting hardware, so reuse or source those components as needed. Bench bleeding the master cylinder before final installation helps remove trapped air and supports proper brake pedal feel. Use DOT 3 brake fluid and bleed the full brake system after installation.
