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 and material strength, such as cast iron construction and accurate bore sizing, to provide dependable braking performance for specific vehicle applications like Chevrolet B350 and Dodge P30 models.

Detailed Product Description

This brake master cylinder features a straight bore type with a diameter of 1.313 inches (33.338 mm), ensuring proper hydraulic pressure for effective braking. The integral single reservoir is cast iron, providing corrosion resistance and structural integrity. The unit includes a master cylinder cap but does not come with mounting hardware, push rod, or brake booster, so these components must be sourced separately. The two mounting holes allow for a secure fitment in compatible vehicles. Both primary and secondary outlet ports have inverted flare types, with thread sizes of 1/2"-20 and 9/16"-18 respectively, facilitating proper brake line connections.

Compatible Vehicles and Common Applications

  • Replacement for brake master cylinder issues in Chevrolet B350
  • Brake hydraulic system repair for Dodge P30
  • Restoration of Plymouth PB350 braking performance
  • Addressing brake fluid leaks or pressure loss
  • Resolving spongy or unresponsive brake pedal feel

Installation Notes and Tips

Ensure the brake system is fully depressurized before removal. This master cylinder requires separate sourcing of mounting hardware, push rod, and brake booster if applicable. Verify thread sizes and flare types on brake lines to match the primary and secondary outlet ports. Bleed the brake system thoroughly after installation to remove air and ensure optimal brake performance.
