Turn brake-pedal effort into hydraulic pressure with the Dorman First Stop Brake Master Cylinder M390268. It is a direct-fit replacement for many vehicles, among them the 1995-1997 Ford Explorer, 1995-1997 Ford Ranger and 1995-1997 Mazda B2300. See the Buyer's Guide tab for the full list. This new aluminum unit is designed to match the design, function and performance of the original master cylinder.
- 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: made entirely from new materials for quality and safety.
- Strict specifications: made to meet rigorous SAE International standards.
Specifications: aluminum master cylinder with a 1.063 in bore diameter and 2 outlets. The rearward outlet size is M10 x 1.0, the secondary outlet thread is M12 x 1.0, and the primary outlet thread pitch is 1 mm. The reservoir and sensor are included. Mounting hardware is not included. Country of origin: China.
A soft or sinking pedal, fluid seeping at the cylinder or a falling reservoir level are signs a master cylinder may need replacing. Diagnose the cause first. If a worn master cylinder on a 1995-1997 Ford Explorer is to blame, this unit replaces it.
