Bike sat for too long and for some reason brake pumped itself up and LOCKED tight. How do I release this thing? Thanks.
Open bleed screw, loosen caliper mounting bolts, and wrestle 'at sonuvagun off the rotor.
Getting it working again is a different story.
also make sure the return port is clear in the master cylinder....
There's a bunch of great ideas in this thread and there are some more things to check, like oxidation if it's been sitting outside or more generally the action of ALL the pistons in master cylinder and calipers. Since brakes are fairly important part of the bike, I'd say have a reputable professional motorcycle mechanic take care of it. (Note: I did not say or imply a dealer.)
Well after a five day stay in the hosp and another eight to get mobile I found it had freed up a little on its on.
Wow, first I've heard of this. Are you okay?
Thanks Roger, I will be. Took a good beating and three days was ICU, collapsed lung was the big deal. Otherwise just severe road rash, ribs, etc. Short ride around the block turned into an adventure! Just got out of the house for the first time in two weeks and the sunshine sure feels good. Will be good as new and slow as ever in no time.
