Detailed Description

MPA Electrical NM3071 is a brake master cylinder engineered to restore braking performance by replacing a worn or leaking hydraulic unit. The design uses an aluminum master cylinder body, plastic reservoir, and a 1.0625-inch bore to match the specified OE application.

What It Helps Fix

• Low or inconsistent brake pedal feel
• External or internal brake fluid leakage at the master cylinder
• Brake pedal travel that increases over time
• Loss of hydraulic pressure in the brake system
• Brake performance issues on front disc brake-equipped vehicles

Installation Notes and Tips

Before installation, confirm the vehicle is equipped with front disc brakes and verify bore size, mounting hole layout, and reservoir configuration against the original unit. Bench bleeding is recommended before the master cylinder is installed on the vehicle. Use DOT 3 brake fluid only, and inspect the brake lines, fittings, and booster interface for wear or contamination during service.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using controlled procedures and an OE sample library to help ensure consistent braking performance out of the box. NM3071 is a new standard replacement part built for the listed Ford and Mazda applications.
