ABSTRACT:
An automatic slack adjuster for vehicle brakes that automatically and continuously compensates for the wear of the brake linings and does not depend on a fixed reference point on the vehicle chassis for actuation of the adjustment mechanism. The present invention has a control arm integral with a ring journalled in the braking lever, an actuating piston rod to rotate the braking lever and actuate the vehicle brake and a flexible strut member extending between and rigidly connected to the piston rod and a transverse surface at the outer end of the control arm. The flexible strut member allows the outer end of the control arm to act as a reference point but allows it to float during operation of the braking lever and returns the reference point to its desired location upon retraction of the braking lever and piston rod.
