COMBINATION HYDRAULICALLY AND MECHANICALLY ACTUABLE DISC BRAKE WITH HYDRAULIC WEAR ADJUSTMENT

摘要

A disc-brake caliper assembly having a hydraulically actuable primary piston is provided with an extendible member including a fluid link between second and third pistons. The extendible member acts as a rigid link through which the brake is mechanically actuated and is extendible at the urging of a spring by addition of fluid to the fluid link to adjust for lining wear.
