Technical Description and Specifications
This brake master cylinder features a straight bore design with a 1.250 inch (31.75 mm) diameter, ensuring precise hydraulic pressure delivery. The aluminum construction offers corrosion resistance and strength, while the plastic reservoir is removable for easy maintenance and fluid inspection. The unit 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 provide a secure fitment, and the primary and secondary outlet ports use inverted flare fittings with thread sizes of 1/2"-20 and 9/16"-18 respectively, compatible with standard brake line connections.
