Turn every press of the pedal into hydraulic pressure at the wheels with the Dorman brake master cylinder M630471 from Dorman - First Stop. It is a direct-fit replacement for the 2007-2011 and 2019 Toyota Yaris, precision-engineered to match the original master cylinder's design, function and performance on the listed applications.

  • Precise replacement: The cylinder housing is built to match the casting material of the original part for similar performance.
  • Durable design: Every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
  • 100% new: Made entirely from new materials for quality and safety.
  • Strict specifications: Built to meet rigorous SAE International standards.

Made from new, high-quality materials, this Toyota Yaris master cylinder is intended as a safe, durable replacement.
