$168.99
Convert brake-pedal force into the hydraulic pressure that operates the brakes with the Dorman First Stop Brake Master Cylinder M630706, a direct-fit replacement for the 2009-2012 Dodge Journey (all engines). It's built entirely from new materials — not remanufactured — and made to meet rigorous SAE International standards.
- Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for comparable performance.
- Fluid-resistant seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new construction: made completely from new materials for consistent quality and safety.
- Key specs: 0.938 in bore diameter with two outlets; secondary outlet thread size 7/16-24.
Signs the original master cylinder may need replacing include a soft or slowly sinking brake pedal, or brake-fluid loss with no external leak; diagnose the cause before replacing. The reservoir, sensor, and mounting hardware are not included — transfer or source these separately, and consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
