Dorman M630201 Brake Master Cylinder New Aluminum Housing with Reservoir

The Dorman M630201 is a 100% new brake master cylinder engineered as a direct OE replacement for select Acura, Honda, and Isuzu vehicles. Unlike remanufactured units, this master cylinder is built entirely from new materials, delivering consistent, reliable braking performance right out of the box.

The aluminum cylinder housing is precision-cast to match the geometry and casting material of the original part, ensuring a proper fit and OE-comparable performance. All internal rubber components are manufactured from high-quality EPDM compound, providing long-term resistance to glycol-based brake fluids and preventing premature seal degradation.

Key Features:

• 1-inch bore diameter — matches OE specifications for proper pedal feel and hydraulic output
• Aluminum construction — matches the casting material of the original for accurate fitment and durability
• EPDM rubber seals — resistant to glycol-based brake fluid for extended service life
• Brake fluid level sensor included — maintains full warning system functionality
• Reservoir included — complete, ready-to-install assembly
• Dual outlet design — M10 x 1.0mm rearward outlet threads, 2 brake line ports
• 100% new — not remanufactured — ensures highest quality and safety standards
• SAE International certified — manufactured to meet rigorous industry standards
