This listing is for a good used rear brake assembly off of a 1994 Honda CR80R. The assembly includes the rear brake caliper, part number 43100-GS2-601, the rear brake master cylinder assembly, part number 43500-GS2-601, and the mounting bracket, guard, and brake pedal. The assembly has practically new brake pads and was working when it was removed from the bike. It probably needs a good flushing. This assembly fits CR80R model years 1992-1994, but may work with other models-verify with your local mechanic for your specific application. Email with any questions.
