$154.99
Turn brake-pedal force into the hydraulic pressure your brakes need with the Dorman - First Stop Brake Master Cylinder M630497. It drops in as a direct-fit replacement for the 2006-2010 Dodge Ram 2500 and 3500 and the 2011 Ram 2500 and 3500 (all engines), precision-engineered to match the design, function, and performance of the original unit.
- Aluminum build: an aluminum master cylinder with a 1.313 in bore and two outlets (rearward outlet M10 x 1.0, secondary outlet thread M12 x 1.0); the housing is constructed to match the casting material of the original part.
- Fluid-resistant components: the rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely from new materials, not remanufactured, and built to meet rigorous SAE International standards.
- What's in the box: the reservoir and fluid-level sensor are included; mounting hardware is not, so consult the vehicle service information for the correct fasteners and whether they may be reused.
The master cylinder converts pedal effort into the hydraulic pressure that actuates the brake circuits. A pedal that slowly sinks to the floor, feels spongy, or won't build pressure can be a sign the master cylinder may need replacing; if a failed master cylinder is the cause, this unit replaces it. Country of origin: China.
