Dorman - First Stop Brake Master Cylinder P/N:M630563
Build the hydraulic pressure that feeds every brake circuit with the Dorman - First Stop Brake Master Cylinder M630190. It drops in as a direct-fit replacement for the 2001-2005 Hyundai Elantra (All engines), converting brake-pedal force into the hydraulic pressure sent out through its two outlets, while the included reservoir stores the brake fluid. If a worn or leaking master cylinder is the cause of a sinking or spongy pedal, this replaces it.
Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
