Dorman - First Stop Brake Master Cylinder P/N:M630395

Convert brake-pedal force into the hydraulic pressure your brakes depend on with the Dorman - First Stop Brake Master Cylinder M630395. It drops in as a direct-fit replacement for the 2004-2005 Kia Spectra (All engines) and arrives 100% new — made entirely from new materials, not remanufactured, for consistent quality and safety.

Dorman precision-engineers each unit to reproduce the original master cylinder's design, function, and performance on the listed vehicles, and builds it to meet rigorous SAE International standards.

• Aluminum housing: the cylinder housing is built to match the casting material of the original part for similar performance.
• EPDM rubber components: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Four outlets, 0.938 in bore: a 0.938 in bore feeds four outlets, with M10 x 1.0 rearward/secondary outlet threads at a 1 mm primary outlet thread pitch.
• Reservoir and sensor included: ships with the reservoir and sensor; mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused.

Signs this part may need replacing include a sinking or spongy brake pedal and brake-fluid loss; diagnose the cause before replacing, since these signs can have other causes. Country of origin: China.
