    Trek 520 Back Brake Sticking

    I have Avid SD-5 w/Dia-Compe 287 Aero levers on my Trek 520. When I engage my back brake and then release it, it sticks a bit in the middle of the release before it returns to open and sometimes it needs a bit of nudging. It's def appears to be an issue in the brake lever itself. Any suggestions of where to look for the problem/how to fix? Thanks.

    despite what you said about the lever - First I'd release the cable from the brake, to see if the lever then moved freely.
    If no, I'd pull the cable free of the housing and try it again.
    If it still didn't return freely, then I'd remove the cable entirely and see what was binding in the lever housing.
    If it DID move freely with the wire out of the housing, I'd replace the cable housing.
