ABSTRACT:
Automatic slack adjuster (10) for a vehicle braking system is provided with a bifurcated driving link (64) which drives an adjustment shaft (44) in a direction backing off the brake adjustment during the initial portion of the brake application stroke and effecting adjustment of the brake during the terminal portion of the brake application stroke. The mechanism connecting the link (64) to the shaft (44) includes an adjustment effecting lever (74) which is engaged with one arm (60) of link (64) through a lost motion connection. A back-off lever (80) is connected to the arm (62) of link (64) with little or no lost motion so that the back-off lever (80) is actuated during the initial portion of the brake actuating stroke before the lost motion between the adjustment effecting lever (74) and arm (60) is taken up. Levers (74,80) are connected to the adjustment shaft (44) by corresponding coiled clutch springs (86,92).
