anyone have a good working condition rear brake caliper. doesnt matter how it looks , just need to work . For a 1992 250. anyone have one laying around going cheap !!!?

thats where the problem lies. The bolt thread and nut for the parking brake has bent and chewed up as is the rubber gaskets which leaks or rather spews brake fluid out. i will need to break stuff to get it all apart! so i need one complete minus pads. Thanks anyway though.  Beginning to think this bike was well used in its short life until storage 12 years ago !!
