I am new to the forum. I recently bought a 2001 F4i. When I bought it the guy just put new tires and I test rode it. Everything worked fine. No noises no nothing. The only thing it really needed was to change the brakes. The pads were kind of worn but they still have some life. Yesterday when I was pushing the bike out of the garage to wash it the front tire locked up on me. I had to drag it in the garage with my brother. It seemed as if the brake was fully applied. There was a lot of pressure on the lever. I looked at the wheel and nothing is rubbing but the pads. I left it alone and later it pushed no problem. Today i went to ride it to the gas station and while on the rode it started to get locked up again. I waited a bit and turned it around. When I got back I looked at the front tire and saw the whole tire, rim, and rotors is spinning in the opposite direction. This is probably the problem right. Please give me your in put. Thanks in advance.

 

Not sure what you mean by tire spinning the opposite way.

But, if the caliper is not releasing, then you probably have a bad caliper. If its both of them not releasing, it could be your master cylinder.

 

i think what he means is the tire on backwards... yet that wouldnt make the wheel lock up. it seems like it'syour brake-lines, master cylinder or caliper. (also check your brake fluid)
