Turn brake-pedal effort into the hydraulic pressure that operates your vehicle's brakes with the Dorman - First Stop Brake Master Cylinder M390389. It drops in as a direct-fit replacement for the 1997-2002 Ford E-250 Econoline, the 1997-1998 Ford E-350 Econoline, and the 1997-1998 Ford E-350 Econoline Club Wagon (all engines). Dorman precision-engineers it to match the design, function, and performance of the original master cylinder on these applications. If a leaking or failed master cylinder is the cause of a sinking or spongy pedal, this replaces it.
- 100% new: built entirely from new materials, not remanufactured, for quality and safety.
- Aluminum housing: constructed to match the casting material of the original part for similar performance.
- Durable EPDM seals: rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- Strict specifications: made to meet rigorous SAE International standards.
The cylinder has two outlets and a 1.25 in bore diameter, with a rearward outlet size of M18 x 1.5 and a secondary outlet thread diameter of 9/16-24. It includes the reservoir and the sensor; mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
