Abstract
A method of varying a rest position and a length of an actuation arc of a lever in a hydraulic disc brake system. The hydraulic disc brake system comprises a master cylinder including a cylinder having a first end and second end and a port communicating with a hydraulic fluid reservoir between the first and the second cylinder ends. A piston is received in the cylinder. The piston has a seal between the cylinder and the piston and the piston is movable within the cylinder by a lever operatively associated therewith to selectively pressurize hydraulic fluid within the cylinder by moving the seal between the port and the second end of the cylinder. The hydraulic disc brake system further comprises a caliper in fluid communication with the master cylinder. The caliper has a pair of brake pads operatively associated with a disc received therebetween. The caliper is actuated by movement of the 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 is variable by movement of the engagement point relative to the rest position along the actuation arc. The method comprises varying a rest position o…
