Anyone rebuilt their rear caliper? Mine is all kinds of mangled from riding in the rain and dust/dirt and it looks like the pistons aren't retracting: the piston side is worn down to 30% and the other side is at 90%, after about 5,000 miles!
I've got an Up & Over bracket on there now but it'd be best to refresh the parts to keep this from being an issue.
I've heard Honda ST1100s share the same brake caliper, but that may just be for the pads: looking at pictures online they don't appear to be the same caliper. Anyone able to shed light on this?
