Product Details

The Dorman M630704 is a 100% new brake master cylinder engineered as a direct-fit replacement for select Nissan models. Unlike remanufactured units, this master cylinder is built entirely from new materials, delivering reliable braking performance right out of the box with no core return required.

Key Features:

  • Precise OE Replacement: Cylinder housing is constructed to match the casting material of the original part for proper fit and similar performance
  • Durable EPDM Rubber Components: All internal rubber seals and components are made from high-quality EPDM compound, providing excellent resistance to glycol-based brake fluids
  • 100% New Construction: Made entirely of new materials — not remanufactured — for maximum quality, safety, and longevity
  • SAE Compliant: Manufactured to meet rigorous SAE International standards for hydraulic brake components
  • Direct Bolt-On Design: Engineered to match the original master cylinder's design and function for a straightforward installation

The Dorman M630704 brake master cylinder restores proper hydraulic pressure to your braking system, ensuring consistent and safe pedal feel. It is an ideal solution for DIY mechanics and professional technicians looking for a quality, cost-effective alternative to OEM replacement parts.
