Keep your brakes supplied with hydraulic pressure using the Dorman First Stop Brake Master Cylinder M630663. This new aluminum master cylinder converts brake-pedal effort into that pressure and sends it out through two outlets. It is a direct-fit replacement for the 2007-2008 Chrysler Pacifica, 2009-2015 Chrysler Town & Country, 2009-2015 Dodge Grand Caravan, 2009-2012 Volkswagen Routan and 2012-2015 Ram C/V. It is precision-engineered to replicate the original master cylinder's design, function and performance on those vehicles.
- Precise replacement: The cylinder housing is constructed to match the original part's casting material 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: 1 in bore diameter, 7/16-24 rearward outlet size and 7/16-24 secondary outlet thread diameter. A reservoir and a sensor are included. Mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether the originals may be reused. Country of origin: China.
Signs a master cylinder may need replacing include a soft or sinking brake pedal, brake fluid leaking at the cylinder, or an illuminated brake warning light. Diagnose the brake system first. If a failed master cylinder is the cause, M630663 replaces it.
