Product Details and Specifications

This Cardone disc brake caliper features a phenolic piston material, which helps reduce heat transfer and corrosion inside the caliper.

Installation Notes and Tips

When installing the Cardone 18-B4991 caliper, use the included hardware kit for secure mounting. Note that mounting bolts are not included and must be sourced separately if needed.
