This is the ratchet from our brake assembly (left). Note the holes in the inner surface. This brake was originally equipped with six friction pucks that rode in these holes. At some point, someone replaced the original pucks with friction rings. Once we told the employees at Warn Service Parts our serial number, they were quick to note that we had the old style ratchet and knew the parts we needed for the upgrade. This is where their technical knowledge came in handy.
