Centric Premium Brake Master Cylinders Product Line

The Centric Premium Brake Master Cylinders line focuses on delivering high-quality brake hydraulics components that meet or exceed OEM specifications. This product line emphasizes precision engineering, durable materials like aluminum for the cylinder body, and practical features such as removable reservoirs and included master cylinder caps. The 130.66014 part exemplifies this approach by combining robust construction with fitment tailored for specific Chevrolet and GMC full-size vans and trucks.

Detailed Product Description

This brake master cylinder features a stepped bore design with a primary bore diameter of 1.575 inches and a secondary bore diameter of 1.252 inches, providing balanced hydraulic pressure for effective braking. The aluminum construction offers resistance to corrosion and wear, while the plastic reservoir is designed for durability and ease of fluid inspection. The single removable reservoir style simplifies brake fluid maintenance. The unit includes a master cylinder cap but does not come with mounting hardware, push rod, brake booster, bleeder hoses, or mounting bracket, so these components must be sourced separately if needed.

  • Improves brake pedal feel and responsiveness in aging brake systems

  • Ensure brake fluid system is properly bled after installation to remove air
  • Use appropriate inverted flare fittings for primary (1/2"-20) and secondary (9/16"-18) outlet ports
  • Mounting hardware is not included; retain original hardware or source replacements
  • Inspect brake booster and push rod components separately as they are not included
