Dorman - First Stop Brake Master Cylinder P/N:M98894

Turn brake-pedal effort into the hydraulic pressure that operates the wheel brakes with the Dorman - First Stop Brake Master Cylinder M98894. This 100% new (not remanufactured) unit is engineered to match the design, function, and performance of the original master cylinder on the listed applications, dropping in as a direct-fit replacement across many 1979-1993 Dodge and Plymouth trucks and vans — including the Dodge B150, D150, W150 and Ramcharger and the Plymouth PB250 and Trailduster. See the Buyer's Guide tab for the full list of applications.

• Cast iron housing: constructed to match the casting material of the original part for similar performance.
• Glycol-resistant seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Outlet specs: 2 outlets with a 1.125 in bore diameter, a 9/16-20 rearward outlet, and a 1/2-20 secondary outlet thread.
• Built to standard: made to meet rigorous SAE International standards; the reservoir is included, while a sensor and mounting hardware are not.

Signs the original master cylinder may need replacing include a pedal that slowly sinks under steady pressure or external brake-fluid leakage at the cylinder. If a failed master cylinder is the cause, this replaces it. Country of origin: China.

Interchange: Manufacturer part number M98894.
