ABSTRACT OF THE DISCLOSURE CONNECTION MECHANISM FOR AUTOMATIC SLACK ADJUSTER An automatic slack adjuster for a vehicle braking system includes a yoke assembly which is pivotally mounted on the adjuster body and in which is adapted to be connected to a push rod actuated by a fluid pressure actuator. The yoke assembly includes a recess having an entrance which is adapted to receive the end of the push rod. An adapter member is threaded on the end of the push rod received in the recess, and a U-shaped connector penetrates the body of the yoke to engage a circumferentially extending groove on the adapter, to thereby define a nonthrust transmitting connection between the yoke and the push rod. The yoke assembly defines a pair of thrust receiving surfaces which circumscribe the entrance to the recess, and a thrust washer slidable on the push rod is held at a thrust transmitting engagement with one of the thrust receiving surfaces by a nut which Is threaded on the end of the push rod. The adapter is stepped to define larger and smaller surfaces with a shoulder therebetween which is adapted to engage the other thrust transmitting surface. Consequently, braking thrust is exerted on the yoke assembly through the push rod, the thrust washer, and the one thrust receiving surface, but if the thrust washer Is moved out of thrust-transmitting engagement with the one surface, thrust may be transmitted to the other surface through the shoulder.
