Product Details

MPA Electrical NM55386 is a brake master cylinder engineered for Nissan Versa brake hydraulic service. It is built to restore braking performance by maintaining proper hydraulic pressure at the master cylinder, helping support firm pedal feel and consistent brake response.

Installation Notes and Tips

Before installation, confirm the vehicle is a 2007-2011 Nissan Versa with front disc brakes and verify the bore and mounting dimensions match the original unit. This master cylinder does not include a reservoir, cap, brake booster, push rod, sensor, or mounting hardware. Use DOT 3 brake fluid and bleed the brake system thoroughly after installation to remove air from the hydraulic lines.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary procedures and strict inspection protocols. That verification process supports consistent hydraulic performance out of the box for the Nissan Versa application covered by NM55386.
