Claim Text:
1. A mechanical double-acting brake caliper assembly, including: two caliper bodies, each having a recess, an axial hole communicated with the recess, the two caliper bodies fixedly connected to each other with the two recesses face-to-face, the two caliper bodies forming a receiving space between and communicating the two recesses; two axially-movable mechanisms, respectively disposed through the two axial holes and axially movably assembled to the two caliper bodies, each axially-movable mechanism including a driven end extending outside a respective one of the two caliper bodies and an actuating end arranged in the receiving space, the actuating end of the respective axially-movable mechanisms provided for driving a lining assembly to move toward an object; two arm members, extending in opposite directions with an included angle from the respective driven ends, each arm member having a first end and a second end corresponding to the first end, each of the first ends fixedly connected to a respective one of the driven ends in a co-rotatable relationship, each of the second ends having an installation portion, one of the installation portions of the second ends provided for a cable to dispose therethrough and the other provided for fixing a distal end of the cable; a first elastic member, having an abutting portion and two elastic arms extending away from each other from the abutting portion, the abutting portion engaged to one of the two caliper bodies, distal ends of the two elastic arms engaged with the respective installation portions; wherein when the cable is pulled, the installation portions approach to each other and the actuating ends of the respective axially-movable mechanisms are driven to move the lining assembly to come toward the object; wherein the distal end of the respective elastic arms is formed with a hook portion, each installation portion has a horizontal trough substantially parallel to the axial direction of the axial hole and a vertical hole communicating with the horizontal trough, the distal end of the respective hook portions has a vertical portion and a horizontal portion extending horizontally from the vertical portion, the vertical portion of the respective hook portions is inserted in the vertical hole of corresponding installation portion, and the horizontal portion of the respective hook portions is elastically abutted within the horizontal trough of corresponding installation portion.
