Detailed Product Description

This disc brake caliper features a single aluminum piston with a 60 mm (2 inch) outside diameter, designed to provide consistent braking force.

Dust boots and caliper slides are included to maintain smooth caliper movement and protect internal components from contaminants.

Inspect dust boots and caliper slides during installation to confirm they are seated correctly for optimal caliper movement.
