Description

Deliver the hydraulic pressure that operates your brakes with the Dorman - First Stop Brake Master Cylinder M630940. It drops in as a direct-fit replacement for the 2015-2019 Hyundai Sonata [All] and 2016-2019 Kia Optima [All]. The master cylinder converts pedal force into the hydraulic pressure that operates the brakes; if a leaking or worn original is the cause of a sinking or spongy pedal, this replaces it.

Precision-engineered to match the design, function, and performance of the original unit on the listed applications, it's built from new, high-quality materials for a safe, durable replacement.

100% new: made entirely of new materials, not remanufactured.
Cast iron housing: constructed to match the casting material of the original part for similar performance.
Durable design: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
Strict specifications: made to meet rigorous SAE International standards.

Includes a single reservoir and a fluid level sensor, with two outlets and a 0.9375 in bore diameter. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Made in China.
