Dorman - First Stop Brake Master Cylinder P/N:M390016
Send hydraulic pressure to your brakes with the Dorman First Stop M630456, a new Hyundai Sonata master cylinder built as a direct-fit replacement for the 2006-2010 Hyundai Sonata and the 2006-2013 Hyundai Azera (all engines). The master cylinder converts force on the brake pedal into hydraulic pressure and sends it to the brake lines through its two outlets.
Dorman precision-engineered this unit to match the design, function and performance of the original master cylinder. It is built from new, high-quality materials for a safe, durable replacement.
A soft or sinking brake pedal or fluid seeping from around the unit are signs this part may need replacing. If a worn master cylinder is the cause, this unit replaces it. Mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
