Rear caliper, disassembled, bore cleaned and checked, lightly honed to smooth the walls. Seal-grooves cleaned and checked, all else: pad-pins, pad spring , air bleeder cleaned and checked, reassembled, two good seals installed. Required: dust seals, pistons (43107-MA7-006, or K&L #32-1174) This is mechanically a decent caliper that could use a coat of caliper paint (from any decent automotive supply). This caliper from a 1983 Aspencade, Interstate or Standard (43100-MB9-781 spec's out, with the exception of the water-guard mount and drilled holes) identical to the GL1200 (all years, all models) (43101-MG9-006 43101-MG9-026 CALIPER, RR.) rear caliper, and the GL1500 rear caliper (43101-MG9-006 or 43101-MG9-026 CALIPER, RR.) in '88 to '92, and takes the same seal-kit and pistons. Of well over 300 bikes, 1100, 1200, 1500: I have one of these available. Rare in good usable condition.
