Abstract
A piston-type air brake actuator includes a cylinder having an internal sliding surface of substantially uniform cross-section, a piston dimensioned to have a substantially air tight, axially slidable fit within the cylinder, and a pushrod rigidly secured to the piston for engagement with a pivoting operating shaft of a disc brake. The piston is provided with a compliant peripheral seal to permit articulation of the piston as the pushrod engages the operating shaft during pivoting motion of the operating shaft.
