Smack the caliper with a rubber malet. The puck in the caliper is stuck.
Have you cracked the bleeder when it start locking up? If it's pressured up and frees up the brake when you crack it, you might start looking at the master cylinder. I guess a collapsed brake hose could do it too, but I've never seen that on a scooter.nope, no good.
1/2 way to work it started dragging again.
I got home at night and popped out the piston from the caliper and there was some nasty chunky fluid in there (But the bore look great) so I cleaned everything out and Ill try again soon.
