Abstract
An actuating mechanism is disclosed as particularly useful for a braking assembly, and especially for a disc brake assembly. The mechanism is a device having elastic properties formed from a plurality of layers, or laminae of rigid (metal, hard plastic) and resilient (elastomer, rubber) members bonded together and to the inside of a casing or caliper housing sealing it therein. The casing together with the bonded and sealed actuator therein is threaded into the caliper housing of the brake assembly. Fluid pressure applied to the casing interior activates the mechanism and it yields by flexing axially. An attached brake shoe or pad is operated by the actuator, given an axial displacement and urged against the brake assembly drum or rotor in a braking action. The actuator mechanism returns the shoe or pad to a neutral, non rotor contacting position automatically when the pressure of the fluid in the casing is relieved.
