Detailed Product Features and Specifications

This Raybestos disc brake caliper is designed as a floating type, which allows for self-adjustment during braking to maintain even pad wear. The aluminum caliper casting reduces unsprung weight, contributing to improved vehicle handling and fuel efficiency. The caliper includes two pistons with a diameter of 59.9 mm, providing balanced clamping force for effective braking. The semi-loaded configuration means the caliper comes partially assembled, including the bracket, simplifying installation. The coated surface finish protects the caliper from rust and environmental damage, extending service life. The bleeder screw thread size M10x1 is compatible with standard brake bleeding tools, facilitating maintenance.
