weird problem. thins morning i took both wheels off my bike to change both tires. left the bike in store room but its still pretty hot out - 95 degrees.

changed both tires then tried to put the wheels back on.

both front and rear brake calipers have closed to a degree that i cannot fit the rotor back in.

avid elixir brakes.

no problems spinning wheels earlier.

whats causing it? how do i fix it?

From the brakes forum

here's the disc brakes FAQ. A glance at your owners' manual will help you know what to do if you need to service something when you're 20 miles out on a trail.

faq doesnt address the issue, thanks tho. i have adjusted the pad contact to be as far out as posssible but still cant fit the rotors in. havent adjusted or added fluid or anything. have ridden it many times lately, no brake issues.

Did you squeeze the brake lever(s) by accident when the rotors where out of the caliper? To fix.... remove pads if possible, insert sacrificial padset into caliper, use a screwdriver to gently pry open calipers.... this should be done slowly, in a twisting motion, rather than trying to use the caliper body to pry the calipers open, graduate in blade size until calipers are open all the way, insert new pads & return spring, feather brakes and break in new pads....

that did it. gf moved the bike maybe she squeezed the lever
you should have gotten

with purchase, a set of plastic spacers that you insert if you remove the wheels, mostly used for shipping or similar. Those prevent the pads from coming together if the lever is squeezed.

this might help in future. http://www.sram.com/_media/techdocs/95-5015-016-000.pdf

I wish I had a $ for every time I grabbed the front brake right after removing the front wheel... I keep a spend set of pads around for just such an emergency. I've also "modified" a putty knife to open the pads... works like a charm. I guess I should pick up some of those little plastic thingies.... would make life easier
A guy in a bike shop showed me once that a heavy-duty downhill tire lever works almost perfectly for prying the pads apart without damaging them. If you have one, that is...
