2002 Ford F-250 Super Duty Brake Master Cylinder Parts Q&A

• Q: How to service and repair the brake master cylinder on 2002 Ford F-250 Super Duty?

  A: Start brake master cylinder repair and servicing by taking out the component from the vehicle while cleaning its outer surfaces. The second step involves removing the filler cap to drain all brake fluid from the system. The first step is disconnecting the brake pressure switch when this component exists. Every step in removing the primary piston assembly begins with pressing down until the snap ring becomes loose and ultimately discards the primary piston assembly. Apply compressed air into the front outlet port with the rear outlet port plugged while checking if the brake pressure switch port requires plugging before discarding the secondary piston assembly. The brake master cylinder bore requires replacement when it is damaged or the technician should clean it with isopropyl alcohol and inspect for damage. Install the new piston assembly seals with clean High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or an equivalent fluid that meets Ford specification ESA-M6C25-A. After the installation of the secondary piston assembly add the primary piston assembly while pushing the snap ring into place with the primary piston. Install the brake pressure switch when needed and return the brake master cylinder into its vehicle position.
