Front brake suddenly grabs?
Hi All, last December I flushed the brake fluid with castrol SRF and a vacuum bleeder. I have the GS911 but a quick forum search reveals that it is not needed for normal bleeding, so I didn't use it.
Since then I rode about 4 times (been raining a bit here in California). 2 out of those 4 times, in each ride there was once when I think the front brake suddenly grabbed a bit, then it releases. Needless to say it was a bit scary. The first time I was pretty upright. The second time was this past weekend, when I was 40-45 degrees into a left turn. When I got home and put the bike on the center stand, I noticed that the front wheel was not really turning relatively freely by hand. After I freed the front wheel with a bit more force, then it started turning relatively freely by hand again.
I took a look at the rotor surface but couldn't see anything obviously wrong - not warped or scratched. The pads seemed ok too. There are no obvious fluids or material around the calipers besides the normal brake dust.
Any one had a similar experience before? Not sure what else to check next. I was going to sell the GS911 so I have it in a sealed box at the moment, and I don't think there will be any codes on this, so I haven't checked.
