Abstract
A method of varying a rest position of a one-piece lever in a hydraulic brake system. The hydraulic brake system comprises a master cylinder including a cylinder and a port, a piston received in the cylinder, the piston having a radial seal between 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 brake system further comprises a caliper in fluid communication with the master cylinder, the caliper having a pair of brake pads operatively associated with the disc received therebetween. The caliper is actuated by movement of the one-piece lever in an arc between a rest position and an engagement point with the pads in engagement with the disc. The length of the arc is variable by movement of the engagement point relative to the rest position along the arc. The method of varying the rest position comprises varying a rest position of the one-piece lever and maintaining the length of the arc as the rest position of the one-piece lever is varied.
