Dorman - First Stop Brake Master Cylinder P/N:M630456
$126.99
Convert your brake-pedal force into the hydraulic pressure that operates the brake circuits with the Dorman - First Stop Brake Master Cylinder M630456. It installs as a direct-fit replacement for the 2006-2013 Hyundai Azera and 2006-2010 Hyundai Sonata (all engines), and is precision-engineered to match the design, function, and performance of the original unit on those specific applications.
- Aluminum housing: the cylinder housing is constructed to match the casting material of the original part, with a 1-inch bore and two outlets (M12 x 1.0 thread).
- Glycol-resistant seals: 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.
- Built to spec: made to meet rigorous SAE International standards; reservoir and sensor included.
The master cylinder pressurizes fluid to the brake system when you press the pedal. Signs it may need replacing include a pedal that slowly sinks under steady pressure, a soft or spongy pedal, or a falling fluid level with no visible external leak — 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: China.
