Abstract:
1. A brake actuating apparatus, comprising: a caliper body comprising a cylinder; a piston liquid-tightly engaged with the cylinder and slidable relative to the cylinder; a plug non-movably engaged with the cylinder and distanced from the piston, the plug comprising a first plug body and a second plug body, the first plug body located between the piston and the second plug body; the first plug body comprising outer surfaces on the side of the piston and inner surfaces on the side of the second plug body; a shaft rotatable about an axis and liquid-tightly passing through the second plug body; a head fixed to the shaft and interposed between the first and second plug bodies, the head rotatable about the axis but not movable along the axis; a first space defined by the cylinder, the piston, and the outer surfaces of the first plug body; a second space defined by the head, the second plug body and the inner surfaces of the first plug body; a fixed amount of brake fluid filled in the first and second spaces; at least one opening formed through the first plug body and interconnecting the first and second spaces such that the brake fluid can flow between the first and second spaces; wherein at least partial rotation of the head about the axis in a first rotational direction relative to the plug is to cause at least part of the brake fluid to flow from the second space to the first space through the at least one opening, which in turn is to cause sliding of the piston in a first direction away from the plug; wherein at least partial rotation of the head about the axis in a second rotational direction opposite to the first rotational direction relative to the plug is to cause at least part of the brake fluid to flow from the first space to the second space through the at least one opening, which in turn is to cause sliding of the piston in a second direction toward the plug.
