About Centric Premium Brake Master Cylinders

The Centric Premium Brake Master Cylinders line focuses on delivering precise hydraulic control and durability for brake systems. This product line features components made from quality materials such as aluminum and plastic, designed to meet or exceed OEM specifications. The 130.66020 master cylinder exemplifies this approach by combining a robust aluminum bore with a removable plastic reservoir, providing a balance of strength and serviceability for Chevrolet and GMC truck brake hydraulics.

Detailed Product Description

This brake master cylinder features a stepped bore design with a primary bore diameter of 1.417 inches and a secondary bore diameter of 0.937 inches, optimizing fluid displacement and pressure distribution. The aluminum construction enhances durability while resisting corrosion. The included plastic reservoir is single-style and removable, facilitating brake fluid inspection and replacement. The master cylinder cap is included, but mounting hardware, brake booster, push rod, bleeder hoses, and mounting bracket are not included, so these components must be sourced separately if needed. The unit has two ports with inverted flare outlet threads—primary at 1/2"-20 and secondary at 9/16"-18—to ensure secure brake line connections.
