Abstract:
1. A method of varying a rest position and a length of an actuation arc of a one-piece lever in a hydraulic disc brake system, the hydraulic disc brake system comprising a master cylinder including a cylinder and a port, a piston received in the cylinder, the piston having a seal between the cylinder and the piston, the piston being movable within the cylinder by a one-piece lever operatively associated therewith to selectively pressurize hydraulic fluid within the cylinder by closing the port, the hydraulic disc brake system further comprising a caliper in fluid communication with the master cylinder, the caliper having a pair of brake pads operatively associated with a disc received therebetween, the caliper being actuated by movement of the one-piece lever in an actuation arc between a rest position and an engagement point with the pads in engagement with the disc, the length of the actuation arc being variable by movement of the engagement point relative to the rest position along the actuation arc, the method comprising: varying a rest position of the one-piece lever independent of the actuation arc while simultaneously substantially maintaining the length of the actuation arc as the rest position of the one-piece lever is varied; and varying the length of the actuation arc while simultaneously substantially maintaining the rest position as the length of the actuation arc is varied.
