    Avid Elixir R SL piston will not fully reset.

    Been trying for an hour to fully reset the piston in the rear caliper with no luck. I've done the front with ease, but this I could not figure out.

    I can fit the disc in between the brake pads, but it is full contact dragging when I spin the wheel. I've tried using the pad spacers that came with the Stumpy, but no way I can force the tool between the pads. I've also tried sticking a flathead and rocking it back and forth with no success. I can hear the brake fluid at the levers swishing around when I rock the pistons with the flathead.

    What else could be the problem? Would air in the brake system do that?

    You should be able to get the pistons to retract with the screwdriver. There could be too much fluid in the system, in which case you can either do a proper bleed, or for a quick fix you can loosen the bleed port on the lever a bit while you pry the pads apart - just be sure to tighten the bleed port while you still have pressure on the pads/pistons, else, you may pull some air into the lever.

    Agree, it's easy to over pressurize Elixirs when bleeding. After I go through the bleeding procedure, take a flat head screw driver and push the pistons in, then put light reverse pressure on the syringe before sealing it back up. You should find slightly more pad clearance..."slightly more".

    Thanks guys. I was able to get enough pad clearance by loosening the valve at the lever and was easily able to shove the pad spacer in place.
