Detailed Product Description

This Centric Premium Brake Master Cylinder features a straight bore design with a diameter of 1.438 inches (36.513 mm), which is critical for maintaining consistent hydraulic pressure in the brake system. The aluminum construction offers resistance to corrosion and wear, extending the service life of the component. The included plastic reservoir is single and removable, facilitating brake fluid inspection and replacement. Both primary and secondary outlets have inverted flare fittings with 1/2"-20 thread size and 20 threads per inch, compatible with standard brake lines on Chevrolet and GMC trucks and vans. The master cylinder cap is included, but mounting hardware, push rod, brake booster, and bleeder hoses are not part of this assembly, so these components must be sourced separately if needed.
