Product Details

MPA Electrical NM55408 is a new brake master cylinder built to restore hydraulic braking performance on Mitsubishi Lancer models with front disc brakes. The aluminum housing and integrated plastic reservoir are paired with a 0.875-inch bore for OE-style brake system operation. MPA Electrical tests each unit against OE specifications using controlled procedures and sample-based validation to help ensure consistent performance out of the box. This part cross-references Monroe Shocks & Struts (e.g., MR527468) for the same application.

What It Helps Fix

• Low or inconsistent brake pedal feel
• Brake fluid leakage at the master cylinder
• Loss of hydraulic pressure in the brake system
• Pedal travel that becomes longer than normal
• Brake performance issues on front disc brake Lancer models

Installation Notes

Verify vehicle fitment by year and brake configuration before installation. This master cylinder uses 2 mounting holes and does not include mounting hardware, brake booster, push rod, sensor, or brake pressure switch. The cap, reservoir, and gasket/seal are included. Bench bleeding is recommended before installation, and the brake system should be filled with DOT 3 or DOT 4 fluid and bled thoroughly after installation.

Quality Assurance

MPA Electrical validates brake master cylinders against OE specifications with proprietary testing protocols and strict inspection standards to support consistent braking performance. Part number NM55408 is a new standard replacement for Mitsubishi Lancer brake hydraulic service.
