The set consists of a forked-end tool to release the tensioner button, and a 5/16" double square offset reversible wrench with E-Z Grip handle. Insert the release tool under the button of the pull-pawl to disengage the anti-reverse mechanism on the slack adjuster. (Spring tension of the pull-pawl will hold the tool in place.) Then use the wrench to adjust the brake to drum clearance.
