So I have a 1982 GL1100 Interstate I picked up over the winter. The motor is finally back together, but when I went to check out the rear brake situation I found the PO had snapped off the bleeder screw. Attempts to remove the sheared bolt proved futile. I had read somewhere that the rear calipers were the same all the way to the 1987 model, but apparently that was incorrect. The rear caliper I received has a 32 on it, where my original unit had a 30 on the side. I also noticed that the new caliper extends further into the wheel than my previous unit. Even tho the caliper mounting bolts line up, it doesn't seem like the caliper will close correctly on both sides. Does anyone have experience on using a newer rear caliper (1984 I think) on an older bike (1982)? Should I just junk this thing and try to find the correct one from 1982? Thanks...

80=81 the same; 82 and 83 both dual pistons but different parts numbers but may fit..

That 30 or 32 on the side of the caliper is the size of the piston diameter, in mm of course.

Post a wanted ad here, or just be patient and get one from ebay.

Personally, I would just drill and tap the bleeder screw hole for an oversized bleeder.

I agree drill and tap the old bleeder replace it with an over size bleeder or plug it

The caliper you got is probably one made for the thicker rotor of an aspencade and/or possibly a left front caliper. It probably will still work.
