Abstract: A deflashing device for removing excess friction material from a dovetail guide of a brake includes a base for supporting an actuator attached to the base, a slide, at least one pair of cutters and a slide guide attached to the base. The slide is in communication with the actuator and positionable by the actuator. The at least one pair of cutters is positioned on the slide opposed to one another and adapted to engage the dovetail guide of the brake. The slide guide is in communication with the slide for slidably mounting the slide to the base wherein the actuator manipulates the slide for removing excess friction material from the dovetail guide of the brake.
