$186.99
Keep firm pedal feel and steady hydraulic pressure moving to both brake circuits with the Dorman - First Stop Brake Master Cylinder M630938. It installs as a direct-fit replacement for the 2014-2016 Kia Soul [All], where the master cylinder converts brake-pedal force into the hydraulic pressure that operates the brake system.
- Cast-iron housing: the cylinder housing is built to match the casting material of the original part for similar performance, with a 0.812 in bore.
- Two outlets: includes a single reservoir and two outlets; the rearward and secondary outlet threads are M12 x 1.0, with a 1 mm primary outlet thread pitch.
- EPDM rubber: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured, and built to meet rigorous SAE International standards.
An integrated fluid-level sensor and reservoir are included. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Signs the original master cylinder may need replacing include a sinking or spongy brake pedal and internal or external fluid leaks; diagnose the cause before replacing. Country of origin: Taiwan.
