Replace a leaking or worn master cylinder and keep hydraulic pressure moving to your Ford's brakes with the Dorman First Stop Brake Master Cylinder M134457. It is a direct-fit replacement for many Ford vehicles, among them the 2002-2004 Ford E-350 Super Duty, the 2005-2006 Ford E-150 and the 2003-2005 Ford E-250. See the Buyer's Guide tab for the full list and engine details.

The master cylinder turns the force on your brake pedal into hydraulic pressure and sends that pressure through the brake lines. This unit is precision-engineered to match the original master cylinder's design, function and performance on the listed applications.

  • Precise replacement: The cylinder housing is built to match the casting material of the original part, for similar performance.
  • Durable design: Every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
  • 100% new: Built entirely from new, high-quality materials for a safe, durable replacement.
  • Strict specifications: Made to meet rigorous SAE International standards.

Signs that a master cylinder may need replacing include a soft or sinking brake pedal, brake fluid leaking around the master cylinder, or an illuminated brake warning light. Other faults can cause the same symptoms, so diagnose the brake system before you replace parts. After installation, bleed the brakes following the vehicle service procedure.

What does a brake master cylinder do?

It converts the force on the brake pedal into hydraulic pressure. It then sends that pressure through the brake lines to the calipers or wheel cylinders.

What are signs the master cylinder may need replacing?

Common signs include a soft or sinking brake pedal, fluid leaking around the master cylinder, or a brake warning light. Other faults can cause these signs, so diagnose the brake system first.

What are the rubber components made of?

All rubber components in M134457 are made of a high-quality EPDM compound, which resists glycol-based brake fluid.

Do I need to bleed the brakes after installing it?

Yes. Replacing the master cylinder opens the hydraulic system, so bleed the brakes following the vehicle service procedure and use the brake fluid your vehicle specifies.
