Dorman - First Stop Brake Master Cylinder P/N:M631028

The Dorman - First Stop Brake Master Cylinder (M631028) converts brake-pedal force into the hydraulic pressure that operates the braking system. It installs as a direct-fit replacement for the 2012-2017 Hyundai Veloster, 2014-2018 Kia Forte, 2013-2017 Kia Forte Koup, and 2013-2018 Kia Forte5 (All engines), and is precision-engineered to match the design, function, and performance of the original master cylinder on those applications.

• Aluminum construction: the cylinder housing is built 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.
• 100% new: made entirely of new materials, not remanufactured.
• Strict specifications: made to meet rigorous SAE International standards.

Specs: 0.875 in bore diameter, two outlets, rearward and secondary outlet thread size M12 x 1.0, and two mounting holes. This listing supplies one master cylinder only — the reservoir, master cylinder cap, mounting bracket, mounting hardware, sensor, bleeder hoses, push rod, and brake booster are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. A sinking or spongy pedal, loss of hydraulic pressure, or brake fluid leakage are signs the original unit may need replacing; diagnose the cause first, since these can have other causes. Country of origin: China.
