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.

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....

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...
