Detailed Description
MPA Electrical NM4308 is a brake master cylinder for Ford F-150 trucks equipped with front disc brakes from 2015 through 2017. It is built from aluminum and tested against OE specifications using controlled inspection processes and sample-based validation to help deliver consistent braking performance after installation. The design follows a standard replacement format for service work where the original hydraulic master cylinder has worn, leaked, or lost pedal firmness. The NM4308 part number is also referenced as Ford FL3Z-2140-B for the same application.
What It Helps Fix
- Low or spongy brake pedal feel
- Internal master cylinder leakage
- Brake fluid loss at the hydraulic unit
- Uneven or inconsistent brake pressure
- Brake performance decline from a worn master cylinder
Installation Notes and Tips
Verify the vehicle is a 2015-2017 Ford F-150 with front disc brakes before installation. This master cylinder does not include a reservoir, cap, push rod, brake booster, sensor, or mounting hardware, so reuse or source the required related components as needed. Bench bleeding the master cylinder before final installation helps reduce trapped air in the hydraulic system and supports proper pedal feel after service.
