Need hydraulic disc brakes guidance
Is there a site out there (other than parktool) that would teach me alot about hydraulic disc brakes. I took my front wheel off and was pumping my brakes slowely and then I realized the pads would not seperate. Now I cant get my front wheel on. 
My brakes are Juicy Seven. Thanks.

^noobie mistake... :-|
never compress the brakes on hydro's. since they're hydraulic, the oil that is forcing the pads together is now holding them together, i never found a website why, but i just know that when you compress them fully, they end up not comming back to home. i'm not really sure what to do but i know that once i partially pressed them on accident, but was still able to get the rotor in. so i slipped my rotor in, and then just pumped the pads a few times, that caused it to go back to normal.
either, there is a way you can stick a screwdriver or something in to the caliper body to contract the pads, or you're gonna have to buy new pads and put them on.

Did your brakes come stock on your bike, or did you buy them seperatly? If so, there should be a red tab that you stick inbetween the pads when you take the wheel off, it stops you from making that mistake!
You'll probably have to get a screwdriver and wiggle it to push the pads apart, although, you might need new pads after.,

I've never ran Avid brakes, so I don't know if it's a closed setup (un-bleedable) However on my Magura's this happend to me once, just take a small piece of would and push on the pads while opening the bleeder valve. Pop you wheel on, re-bleed, ride, rinse and, repeat.

Best way to get them undone is either, take the pads out totally and then use a screw driver to push the pistons back in. Or get a playing card and slip that inbetween the pads, then slip another one in etc.
To stop this problem i usually put a piece of cardboard inbetween the pads and then use an elastic band to clamp the lever. This holds the cardboard in place and stops the pads locking.
