Product Line Details: Centric Premium Semi-Loaded Disc Brake Calipers

The Centric Premium Semi-Loaded Disc Brake Calipers line offers semi-assembled calipers that include essential hardware such as mounting brackets, abutment clips, and bleeder screws.

Technical Specifications and Features

This disc brake caliper features a cast iron body for durability and heat dissipation. The floating caliper design incorporates a single 31mm steel piston, providing reliable braking force. The inlet thread diameter is M10x1.0, compatible with banjo and open fitting types, facilitating fluid connection. The caliper includes a bleeder screw with M7x1.0 thread size for easy brake fluid bleeding. The gray finish and Mo80 casting number identify the caliper's manufacturing details. Included mounting hardware consists of the bracket and abutment clips, though mounting bolts and brake pads are not included.
