Detailed Description

The MPA Electrical NM4155 brake master cylinder is built to restore braking performance on Ford Super Duty trucks equipped with front disc brakes.

What It Helps Fix

  • Soft or low brake pedal feel
  • External brake fluid leakage at the master cylinder
  • Loss of hydraulic pressure in the brake system
  • Uneven or inconsistent braking response
  • Brake warning concerns related to master cylinder wear

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and brake configuration before installation. This master cylinder does not include mounting hardware, brake booster, push rod, or brake pressure switch. Use DOT 3 or DOT 4 brake fluid as specified for the vehicle, and bleed the brake system thoroughly after installation to remove trapped air.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict protocols. The result is a standard replacement part built for consistent braking performance on compatible Ford Super Duty applications.
