If a worn or leaking 2009-2015 Honda Pilot master cylinder is behind a soft brake pedal, the Dorman M630603 brake master cylinder is built to take over the job of converting pedal effort into hydraulic pressure for the brakes. It is a direct-fit replacement for the 2009-2015 Honda Pilot with all engines, one per vehicle, and is precision-engineered to replicate the original master cylinder's design, function and performance.
- Matched housing: The aluminum cylinder housing is built to match the original part's material for similar performance.
- Fluid-resistant rubber: Every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: Made entirely of new, high-quality materials for a safe, durable replacement.
- Strict specifications: Made to meet rigorous SAE International standards.
Specifications: 0.875 in bore diameter and two outlets. The secondary outlet thread diameter is M12 x 1.0, the rearward outlet size is M12 x 1.0, and the primary outlet thread pitch is 1 mm. A single reservoir and a sensor are included. Mounting hardware is not included. Country of origin: Taiwan.
Signs a master cylinder may need replacing include a soft or sinking brake pedal, brake fluid seeping at the master cylinder, or a lit brake warning light. Confirm the cause first. Then bench-bleed the new unit and bleed the brake system as directed by the vehicle's service information.
