Abstract: A marking and measuring device for assessing a need for a brake adjustment includes a shaft. A marking means is selectively couplable to a first end of the shaft, positioning a user to grasp the shaft proximate to a second end of the shaft and to manipulate the shaft so that the marking means leaves a mark on a push rod of a brake. A ruler is coupled to the shaft proximate to the second end. The shaft is configured to be grasped in the hand of the user proximate to the first end of the shaft, positioning the user to abut the second end to a brake cylinder so that the shaft is substantially parallel to the push rod. The ruler is configured to measure the distance traveled by the mark on the push rod when the brake is actuated to ascertain a need for a brake adjustment.
