Product Details

MPA Electrical NM3047 is engineered as a brake master cylinder replacement for Ford E-150, Ford E-150 Club Wagon, and Ford Econoline models equipped with front disc brakes. The aluminum housing and plastic reservoir are built to match the listed application requirements, while the 1.125-inch bore supports hydraulic pressure delivery for normal braking operation. MPA Electrical tests each unit against OE specifications using controlled processes and sample-based validation to help ensure consistent performance out of the box. This part number NM3047 also cross-references 1C2Z2140AA and F8UZ2140BA 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
• Soft pedal response after master cylinder wear
• Brake performance issues on Ford E-150 and Econoline front disc brake setups

Installation Notes and Tips

Verify the vehicle is equipped with front disc brakes before installation. Bench bleeding the master cylinder before final assembly helps remove trapped air from the hydraulic circuit. Confirm the mounting hole spacing, reservoir orientation, and brake line connections match the original unit on your Ford E-150, E-150 Club Wagon, or Econoline. Use fresh DOT 3 brake fluid and inspect the rest of the brake system for leaks or worn components during service.

Quality Assurance

MPA Electrical uses OE sample references and strict testing protocols to validate brake master cylinders against original specifications. That process supports consistent hydraulic performance for the listed Ford E-Series applications, including 1997-2003 Ford E-150 Econoline fitments and related models.
