Product Details

MPA Electrical NM55002 is engineered to restore braking performance by replacing a worn or leaking master cylinder in the hydraulic brake system. The unit is tested against OE specifications using controlled processes and sample-based validation, helping deliver consistent brake pedal feel and fluid pressure right out of the box. This part number NM55002 is listed for 1988-1991 Honda CRX, 1993-1995 Honda Civic, and 1994 Honda Civic del Sol models with front disc brakes.

This part cross-references OE numbers 46100SH3G11 and 46100SR3911 for the same application.

What It Helps Fix

• Low or sinking brake pedal feel
• External or internal master cylinder fluid leakage
• Uneven hydraulic pressure in the brake system
• Delayed brake response during normal driving
• Brake fluid loss around the master cylinder assembly

Installation Notes and Tips

• Verify vehicle fitment by year, make, model, and front disc brake configuration before installation.
• Bench bleed the master cylinder before connecting brake lines to reduce trapped air.
• Use clean DOT 3 or DOT 4 brake fluid only.
• Inspect brake lines, fittings, and the booster mounting surface for wear or contamination during service.
• Follow the vehicle service manual for torque and bleeding procedures after installation.

Quality Assurance

MPA Electrical validates each brake master cylinder against OE specifications using proprietary testing processes and strict inspection protocols. The result is a standard replacement part built for consistent hydraulic performance on the listed Honda Civic, Civic del Sol, and CRX applications.
