    Brake Jam

    Ok so I have Juicy three brakes and my lever got pushed without the tire in. So the caliper collasped on itself. Now I can not get them to retract. I have tried useing a flat head screw driver and pushing. I've pushed pretty hard so I just don't know what to do. Any ideas.
    Thanks

    There really shouldnt be a problem spreading the pistons apart with something like a screwdriver. If for some reason you have fluid lock put a hose on the bleeder side of the caliper then push the pads with a screwdriver so the caliper slips over the rotor. Slip a couple .015 feeler gauges between the rotor and pads then seal caliper.

    It really shouldnt but there are never any guarantees on anything. Which brake is giving you the problem, front?

    maybe try removing the bleed screw on the lever to releave the pressure so the pistons can go back in?

    It could be that there not sitting level which would make pushing them back in really hard.

    well if the pistons are that far out you might have to bleed the brake anyway. How far out are they? Got any pics?

    whoa

    Take off the front caliper, remove the pads and squeeze the pistons closed with a set of pliers. If this is too invasive for you, put a credit card (expired) on the face of the piston and a cloth on the caliper body and close the pistons with the pliers. I do this with my Shimanos every now and then to keep the pistons moving through the range properly.

    This "prying" that some speak of works, but sometimes you need a little more.

    You should be able to move them back to the open position with a flat screwdriver. Just slide it in between the pads and twist as if you were tightening a screw. It may take a little effort so dont give up to early. Leave the pads in, if any damage occurs its to the easily replaceable and cheap pads. Afterwards, you may want to remove the pads and give them a light buffing with some fine grit sandpaper to remove any gouges or grooves and avoid scarring your rotor. Good luck, what you did was really pretty simple and not even an issue.
    Ouch
