Generate the hydraulic pressure that pushes fluid to the brakes with the Dorman First Stop Brake Master Cylinder M630188, a direct-fit replacement engineered to drop in like the original master cylinder on the 2001-2003 Hyundai Elantra [All]. It converts brake-pedal effort into hydraulic pressure and feeds it out through four outlets to the brake circuits.

  • Precise replacement: the aluminum cylinder housing is constructed to match the casting material of the original part for similar performance.
  • Durable design: 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.
  • Strict specifications: made to meet rigorous SAE International standards.

It has a 0.875 in bore diameter and four outlets, with rearward and secondary outlet threads of M16 x 1.5 and M10 x 1.0. A reservoir and a sensor are included; mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Signs the master cylinder may need replacing include a soft, sinking, or spongy pedal or fluid loss — diagnose the cause first, and if the original master cylinder is at fault, this replaces it. Country of origin: China.
