Product Details

MPA Electrical’s New with front disc brakes line focuses on replacement brake hydraulics for vehicles that need OE-style fit and function. NM55415 is tested against OE specifications using controlled processes and sample-based validation, helping ensure consistent braking performance after installation. This brake master cylinder does not include a brake booster, push rod, mounting hardware, sensor, brake pressure switch, or mounting bracket.

This part cross-references Monroe Shocks & Struts (e.g., 46100TK4A01, 46100TL1G01) for the same application.

What It Helps Fix

• Low or inconsistent brake pedal feel
• Internal master cylinder leakage
• Brake fluid loss at the master cylinder
• Delayed hydraulic response during braking
• Wear-related braking performance decline

Bench bleeding the master cylinder before installation helps remove trapped air from the hydraulic system. Use only DOT 3 or DOT 4 brake fluid and inspect the brake lines, reservoir connections, and booster interface during service.
