Detailed Product Features and Specifications

This Centric brake master cylinder features a straight bore type with a bore diameter of 1.250 inches (31.750 mm), providing precise hydraulic pressure control. The aluminum construction enhances corrosion resistance and strength, while the plastic reservoir is designed for easy fluid monitoring and maintenance. The single removable reservoir style simplifies fluid replacement and 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 ensure secure installation, and the two ports feature inverted flare thread types—primary outlet with 1/2"-20 threads and secondary outlet with 9/16"-18 threads—compatible with standard brake line fittings. This part is engineered to meet the hydraulic requirements of Chevrolet Astro and GMC Safari brake systems, ensuring proper fit and function.
