Anybody know what can possibly cause front wheels to lock up, the front brake lever to go stiff while riding?
I was riding around and all the sudden the bike locked up like that, to the point where I can't even turn the bike off and push it. I started the bike back up, let the bike rest for a bit, then the lever would loosen up slightly, and I tried revving real hard to overcome the brakes, sometimes it would allow me to do so for a while, and I'd be able to move the bike forward for a while, but as the bike decelerates, it would almost always start to stiffen and lock up entirely again.
Any clues what can be causing this problem?
I also hear some sort of small grinding noise in the front.
