Product Features and Specifications

This brake master cylinder features a 1.000 inch (25.4 mm) straight bore design, which is critical for maintaining proper hydraulic pressure. The integral single reservoir is cast iron, providing a robust fluid containment system. The part includes a master cylinder cap but does not come with mounting hardware, push rod, brake booster, or bleeder hoses, so these components must be sourced separately if needed. The two mounting holes allow for secure attachment to the vehicle’s firewall or mounting bracket.

Common Issues Addressed by This Master Cylinder
