ABSTRACT:
An automatic slack adjuster for a vehicle braking system includes a yoke assembly which is pivotally mounted on the adjuster body and 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 thrust receiving surface which circumscribes the entrance to the recess, and a thrust washer slidable on the push rod is held at a thrust transmitting engagement with the thrust receiving surface by a nut which is threaded on the end of the push rod. Consequently, braking thrust is exerted on the yoke assembly through the push rod, the thrust washer, and the thrust receiving surface.
