ABSTRACT:
An automatic slack adjuster for over-the-road vehicle brakes is adapted to be mounted between the brake chamber and brake operating shaft, for example an operating shaft known as an S cam shaft. The slack adjuster includes a body having a lever arm pivotally connected thereto, which lever arm is connected to the brake chamber through a brake operating rod. A drive member is fixed onto the brake operating shaft and is movably positioned within the body. There is an adjustable connection between the lever arm and the drive member for adjusting the relationship between the drive member and body in response to the body movement required for a brake application. The adjustable connection provides for incremental adjustment and is responsive, during brake application movement of the lever, for both sensing and taking up a limited amount of slack.
