Detailed Product Features and Specifications
This Centric Premium Semi-Loaded Disc Brake Caliper features a cast iron body that provides strength and heat resistance necessary for heavy-duty braking applications. The caliper uses two phenolic pistons, each measuring 44.5 mm in diameter, which help reduce heat transfer to the brake fluid and improve overall braking efficiency. The floating caliper design allows for self-alignment during braking, reducing uneven pad wear.
The inlet thread size is M10x1.0 with a banjo fitting type, facilitating secure hydraulic line connections. The caliper comes with a bleeder screw (M10x1.0 thread) included for easy brake fluid bleeding during installation or maintenance. Abutment clips and a mounting bracket are also included, although mounting hardware and brake pads are not part of this assembly.
