ok so my 2006 ttr-125 had a popped front tube. The bike ran great and had no problems with the brakes or anything and the front wheel spun freely without a problem. I took the front wheel off and took it to the shop and got a new tube put in. I then put the front wheel back on the bike and then went to put the caliper on and it won't fit! So I remove the brake pads on it and try again. Nothing! Still won't fit! This doesn't make any sense???!! The wheel spins perfectly free without the caliper on. I had to force it in as hard as I could and finally got it on (without brake pads) and the wheel will not spin at all. How on earth would this be possible?
