Abstract
An actuator mechanism for a braking system employing multiple disc brakes to insure an air gap between the pressure plate of the brake stack and the piston head of a piston. The piston is mounted in a cylindrical housing with an end wall to which a rod is secured. The rod extends into the piston and has a hardened ball on its end for engagement by a deformable sleeve. The deformable sleeve is connected to an outer cylindrical tube for movement therewith. Such outer tube has a flange on one end that slidably engages the cylindrical wall of the piston and a ring on the other end that is adapted to engage an annular spring retainer member slidably mounted on the outer tube. The piston has an inwardly extending annular abutment that engages the retainer member with a coil spring encircling the outer tube having one end engaging the flange and the other end engaging the retainer member to provide widely spaced footprints for the spring. Such spring biases the piston after a braking action to re-establish the air gap.
