A trigger mechanism is taught which actuates an overtravel control apparatus of a slack adjuster in a railway vehicle brake rigging in response to the measured travel distance of a brake cylinder piston rod. The triggering mechanism includes an elongated hollow member secured to one end of the slack adjuster housing. An abutment surface carried by an extension member secured to one end of the overtravel control apparatus which moves reciprocally within the hollow member. A pivotal connection is secured adjacent an aperture formed in the wall of the hollow member. A lever device is pivotally connected to such pivotal connection and positioned to engage at one end thereof the abutment surface and having the other end movable in response to the brake cylinder piston rod travel distance.
