An automatic slack adjuster for a vehicle brake is disposed between a piston and another component, such as a counter piston, of a hydraulic actuator. The adjuster mechanism is housed in an encapsulating container which is positively attached to the piston. A strut, on which an auxiliary mechanical actuator fitted to said other component acts, is in screw-threaded connection with a nut of the adjuster mechanism. The adjuster mechanism is of the incremental type and is adapted to turn the nut responsively to excess axial travel between the container and the strut upon hydraulic brake application, the strut being sealed to said other actuator component. Grossly excessive travel between the piston and the other actuator component beyond the maximum possible travel between the strut and the container is permitted by displacement of the strut relative to said other component. |
