Help maintain firm, dependable pedal response with this Dorman brake master cylinder, part number M630604 from the First Stop line, a direct-fit replacement for the 2008-2012 Honda Accord and 2009-2014 Acura TSX. The master cylinder turns the force of your foot on the pedal into hydraulic pressure, which the brake lines carry to the brakes at each wheel.
Dorman engineered this unit to match the original master cylinder's design, function and performance on the listed applications. It is built from new, high-quality materials for a safe, durable replacement.
- 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: Made to meet rigorous SAE International standards.
Signs a master cylinder may need replacing include a soft or spongy pedal, a pedal that slowly sinks under steady pressure, or brake fluid leaking at the cylinder. These symptoms can have other causes, so diagnose the brake system before replacing parts. If a failed master cylinder is the cause, this unit replaces it. Bench bleeding before installation and bleeding the brake system afterward is standard practice, so follow the vehicle service information for your 2008-2012 Honda Accord brake master cylinder replacement. See the Buyer's Guide tab for engine details.
