My front brakes like to grab, just not release. PO said he rebuilt the calipers and I have no reason to doubt him. Now, when I squeeze the lever they grab nice and tight but won't release. The lever remains firm but the pads won't back off enough to let the wheel spin, they're not locked up, just won't release enough to easily spin the tire. I know a little bit of drag is normal but this is a lot of drag, like you're lightly holding the front brake lever. Is this a caliper problem, master cylinder issue or something to do with Yamaha's awesome anti-dive mechanism that adds 23 pounds of unsprung weight to the front end?
