Abstract
An improved brake actuator is disclosed that automatically adjusts for brake pad wear, thereby retaining a given retraction space from a fully actuated position. The actuator is hydraulically actuated and the components for positive retraction are housed within the hydraulic actuator, thereby protecting the components from the elements. The brake actuator has particular application for a ring brake having opposed cylindrical braking surfaces. An improved self-locking brake pad is also disclosed.
