Dorman - First Stop Brake Master Cylinder P/N:M630726
$253.99
Convert brake-pedal force into the hydraulic pressure that feeds both brake circuits with the Dorman - First Stop Brake Master Cylinder M630726. It drops in as a direct-fit replacement for the 2007-2013 Suzuki SX4 and the 2012 Suzuki SX4 Crossover (All engines), engineered to match the design, function, and performance of the original master cylinder on those specific applications.
- 100% new: built entirely from new materials — not remanufactured — and made to meet rigorous SAE International standards.
- Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
- EPDM rubber components: the rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- Two-outlet layout: features a 0.875 in bore with two outlets (M10 x 1.0 thread, 1 mm pitch); reservoir and sensor are included.
The master cylinder pressurizes the fluid that operates the brakes when you press the pedal. Signs it may need replacing include a soft, sinking, or low pedal and brake-fluid leaks; diagnose the cause before replacing. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
