    replaced pads, now rotor won't fit

    Replaced pads in Avid Elixir CR brakes. Pried pistons apart, took out old pads, put in new ones, pried them apart more/again, and couldn't get the rotor to fit in the clearance b/w the new pads. these brakes have a "contact" adjustment at the lever, dialed it all the way out. managed to get the rotor in but the brakes just drag, they're totally tight.

    From the look of it the pistons are fully recessed, but I guess they must not be?? I have no idea what to do other than head to the LBS. Any suggestions????

    Thanks.

    The pistons are not fully retracted- they need to be flush with the caliper. Two suggestions: use a 3/4" or 19mm wrench to pry them apart further (remove the new pads, use the box end and place the edge of it inside the caliper and position on the middle of one of the pistons and pull the wrench in the opposite direction; then do the same on the other piston) or use a large flat blade screwdriver (reinstall the old pads, insert screwdriver in between the pads and gently turn the handle back and forth).

    My elixirs came with a red plastic "wedge" thing that jams between the pads to spread things out.

    In the photo at the following link, the thing I'm talking about is smack dab in the middle

    Universal Cycles -- Avid Professional Bleed Kit
    But if you close your eyes it becomes so easy to see

    Exactly . . . one of these: AVID ELIXIR Pad Spacers/ Bleed Blocks Biscuits LIKE NEW | eBay

    Use those with your OLD pads in place to push the pistons back in place most of the way. Then put the NEW pads in and repeat which should push them ALL the way back in.

    ^ Why would someone pay for something so elementary like that?

    Because they lost the one that came with their brakes?

    I have serviced my pads also - found this tool is excellent for pushing in the pads - its worth it if you can service your own brakes. - Park Tool Co. PP-1 : Hydraulic Piston Press : Brake Tools

    Amazon has it for 14 bucks...

    If you have excessive fluid in the system, you might need to crack the bleed screw on the caliper, so it will allow some fluid to escape as you pry the pads apart. Be careful not to get any fluid on the new pads.
