Front rotor touching caliper?

I just put new tires on my bike and when I put the front tire back on, the right caliper is touching the rotor. I'm not sure what's causing it, I took the caliper off and tried twisting the caliper mounts to make it line up better but it didn't seem to help much. I'm not sure why but it seems like only the pistons on the inside are pushing out on the pads causing the pads on the other side to push in making it out of line. Any suggestions are appreciated.

Thanks,
Kane S.

try flipping the rim the other way around. the rim should only go on one way, look at the rotors, i think theyre labeled L and R.

Touching the caliper? Not the pads. If the pads are rubbing... that's normal. You should get a couple of revolutions out of it if you spin it by hand. If the rotor is touching the caliper... you did something really wrong.

I got it figured out, I mounted the tire the same way the oem one came off and it was backwards, when I remounted it the same way I put it back on where the tire was running the right way but the wheel was backwards. It still only turns from 1-2 times when I spin it but I think that's just the pads dragging. I feel like and idiot.

Don't, it's happened to all of us. What's worse is when it happens multiple times. LOL

I got it all figured out but when I got it all put back together the brakes seem to be dragging. I've done everything correctly, per the manual, but when I spin the front tire it'll only spin about 1 revolution. It just seems really tight. Any recommendations about what to do to fix this?

Thanks,
Kane S.

1 revolution may not be a problem. Have you ridden the bike since the changes? The caliper pistons may need to re-center on the rotor.

Another step I like to take when changing the front: before tightening the axle pinch bolts, lower the bike off the stand and bounce the front suspension a few times. This helps release any tension in the forks on the axle. Don't forget to tighten the pinch bolts when done.

Yeah, I've ridden it and it didn't loosen up at all. I tried the bouce thing and it didn't do anything either. When I say it'll only spin once, that's with me spinning it pretty hard. It probably takes 1-2 lbs of force to turn it at all.

When my brakes had excessive drag, I changed the calipers. I'm guessing that the seals around the pistons were swelled up and wouldn't let the pistons fully release pressure off the pads and rotors.

Excessive drag being a pretty hard spin and only 1 Rev.
