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 components such as mounting brackets and abutment clips, simplifying installation. This product line focuses on providing durable cast iron calipers with steel pistons designed for consistent braking performance. The semi-loaded design means pads and mounting hardware are not included, allowing for customization based on specific brake pad preferences.
Technical Description and Features
This disc brake caliper features a floating design with a single 35mm steel piston, providing reliable clamping force for the brake pads. The caliper casting is made from cast iron, offering durability and resistance to heat generated during braking. The inlet fitting supports both banjo and open types with a 10mm M10x1.0 thread diameter, ensuring compatibility with standard brake lines. The included mounting bracket and abutment clips facilitate secure installation, although mounting hardware and brake pads are not included. The gray finish helps protect against corrosion, extending the caliper's service life. Bleeder screws with M7x1.0 thread size are included for proper brake system bleeding and maintenance.
Applications and Problem Solving

Installation Notes and Tips
Ensure the mounting bracket included with this caliper is properly secured using the correct bolts (not included). Verify the inlet fitting type matches your brake line configuration before installation. Since brake pads and mounting hardware are not included, source compatible components separately. Bleed the brake system thoroughly after installation using the included bleeder screw to remove air and maintain optimal brake performance. Follow manufacturer torque specifications for all fasteners.
