Did you ever get to have a look at the speed sensor itself? Had a problem with mine as a couple of lads here did but I don't think it was being erratic it just stopped working........ Sounds more like a poor connection, I also had this problem(yea I'v had alot of problems haha).
I hope it's not this but worth a little look, the main speedo connection in the junction box under the tank beside the coolant cap is the big white connection, it's the biggest one in that box, maybe just unplug and check for a little corrosion, mine corroded that much that I'm now missing 4-5 little connectors, by sheet luck I got the speedo and lights working and I had to cable tie it together as everytime I hit a bump in the road I lost everything( not fun at night).
The brake caliper won't really effect this unless you damaged the wire going to the speed sensor.
If you get a chance just make sure both lugs are there and in working order
