Supply the hydraulic pressure your brakes rely on with the Dorman First Stop Brake Master Cylinder M630366, a direct-fit 2005-2007 Kia Sportage master cylinder that also fits the 2005-2007 Hyundai Tucson with all engines. Dorman precision-engineered this unit to replicate the original master cylinder's design, function and performance on the listed applications, and built it from new, high-quality materials for a safe, durable replacement.
Specifications: 1 in bore diameter, three outlets, and an M12 x 1.0 rearward outlet. The reservoir and sensor are included. Mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether the originals may be reused. Country of origin: China.
The master cylinder converts brake pedal force into hydraulic pressure that travels through the brake lines to the wheel brakes. Signs it may need replacing include a soft or sinking pedal, fluid seeping around the unit, or a steadily dropping fluid level. Diagnose the cause before replacing, and follow the vehicle service procedure for installation and brake bleeding.
