Re: 08 1000rr front brakes locked up/ crash
I was riding my '93 RS 125 a track day years ago, and had something similar happen. Going down the back straight at Mosport's Rider Development track, the front brake locked up on me. Luckily I was able to pull off, but I couldn't move the bike. I had to wait until the brake cooled before the wheel would turn.
What happened was through use some crud had gotten into the brake lines and fluid, and somewhere along the way a tiny hole in the master cylinder had gotten clogged up. With heat from braking there was some expansion of the fluid, but it couldn't get back up into the reservoir, and could only move the pistons in the caliper. Once that hole got cleared, bleeding the system was super easy, and the brake worked like new.
May not be what your problem is, but if there is dirt in your system, your master may need to be cleaned out as well as the calipers. Just a thought.
