Details on Centric Premium Semi-Loaded Disc Brake Calipers
The Centric Premium Semi-Loaded Disc Brake Calipers line is designed to provide a balance between ease of installation and reliable braking performance. This semi-loaded caliper includes essential components such as the mounting bracket, abutment clips, and bleeder screw, but does not include brake pads or mounting hardware.
