Fitment & Compatibility
Use the intended rotor and bracket dimensions to establish compatibility. The chosen pad compound, master-cylinder volume and brake balance must be considered with this caliper’s piston sizes.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
