Convert firm brake-pedal pressure into the hydraulic force that applies the brakes with the Dorman First Stop Brake Master Cylinder M630610. It drops in as a direct-fit replacement, precision-engineered to match the design, function, and performance of the original master cylinder on the 2009-2019 Chrysler 300, 2009-2019 Dodge Charger, and 2011-2019 Dodge Challenger (All engines).
This unit has two outlets and a 1.063 in bore diameter; the rearward/secondary outlet is M14 x 1.5 and the primary outlet uses a 1.5 mm thread pitch. The reservoir and fluid-level sensor are included. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. A brake pedal that slowly sinks to the floor, feels spongy, or a loss of brake fluid can be signs this part may need replacing; if a failed master cylinder is the cause, this replaces it. Country of origin: China.
