Abstract
A parking brake actuator for a disc brake caliper. The parking brake actuator includes a tapered collet having an axial bore, the tapered collet slidably positionable within a bore of the disc brake caliper; an actuator rod having a first end and a second end, the actuator rod slidably positionable within the axial bore of the collet; means for receiving a force for placing the parking brake actuator in a non-actuated condition; and a first biasing means structured and arranged to apply a force sufficient to place the parking brake actuator in an actuated condition when the force for placing the parking brake in a non-actuated condition is reduced or eliminated.
Claims34
A parking brake actuator for a disc brake caliper, said parking brake actuator comprising:
- a tapered collet having an axial bore, said tapered collet slidably positionable within a bore of the disc brake caliper;
- an actuator rod having a first end and a second end, said actuator rod slidably positionable within said axial bore of said collet;
- means for receiving a force for placing the parking brake actuator in a non-actuated condition;
- and
- a first biasing means structured and arranged to apply a force sufficient to place the parking brake actuator in an actuated condition when the force for placing the parking brake in a non-actuated condition is reduced or eliminated.
A disc brake caliper having an integral parking brake, the disc brake caliper having disposed in a generally horizontal cavity therein a parking brake actuator structured and arranged to lock the parking brake by applying an actuation force in a direction away from a disc brake pad disposed within said caliper.
A disc brake caliper comprising a service brake actuator disposed in a first cavity therein and a parking brake actuator disposed in a second cavity therein, wherein the parking brake actuator comprises an actuator rod disposed within a collet assembly comprising a collet within a sleeve, and is structured and arranged to lock the parking brake by a force applied to the collet in a direction away from a rear face of a disc brake pad disposed within said caliper.
