Hello all. My question is”How do you remove/unscrew the RH caliper pivot bolt”? 1977 R100S. I was able to remove the LH caliper pivot bolt but not the RH one. Screwing in the axle clamp bolt into the pivot bolt results in the clamp bolt just going around and around and not bottoming out so that I can pull the pivot bolt down and out. Any and all suggestions are appreciated!
