摘要： A master cylinder for a bicycle hydraulic disc brake includes a cylinder having a port in fluid communication with a hydraulic fluid reservoir. The port opens to the cylinder between first and second ends of the cylinder. A piston within the cylinder is movable between a select starting position with the seal between the first end of the cylinder and the port opening with the piston a select distance from the port opening and a pressurized position with the seal between the port opening and the second end of the cylinder. A dead-band adjustment structure is operatively associated with the piston for moving the select starting position to adjust the select distance between the port opening and the seal. A lever is pivotably attached to the housing and is operatively associated with the piston to move the piston between the select starting position and the pressurized position as the lever is pivoted between a rest position and a fully-actuated position. A compensating structure operatively associated with the dead-band adjustment structure and the lever maintains the lever in a select rest position as the dead-band adjustment structure is actuated to move the select starting position.

摘要： A cycle has a frame with wheel supports extending on opposite sides of a wheel rim operatively associated with the cycle frame. The cycle frame includes a pair of brake attachment studs on each wheel support for mounting a brake in operative association with the wheel rim. The brake with pad attitude control consists of first and second brake arms, each having a proximal and a distal end. Each brake arm is pivotally mounted about its proximal end to one of the brake attachment studs of a pair of brake attachment studs. A cable extends between the distal ends of the first and second brake arms which, upon application of force to the cable, pivots the distal ends of the first and second brake arms toward one another. A brake pad mounting bracket is pivotally attached to each brake arm. The brake pad mounting bracket includes a structure for maintaining a brake pad with a brake pad assembly in a select position relative to the brake pad mounting bracket. First and second arch members each have a proximal and a distal end. The proximal end of each arch member is fixedly attached to one of the brake pad mounting brackets. The distal ends of the arch members are pivotally attached. The first and second arch members cooperatively form an arch over the pad mounting brackets of a size sufficient to receive a cycle rim and an associated tire.

摘要： A master cylinder for a bicycle hydraulic disc brake comprises a housing defining a cylinder, the cylinder having a first and a second end along its axis. A hydraulic fluid reservoir has a port between the hydraulic fluid reservoir and the cylinder, the port having an opening between the first and second cylinder ends. A piston having a seal resides in the cylinder with the seal between the piston and the cylinder. The seal has a leading seal edge with the leading seal edge being movable solely between the first cylinder and the port opening to vary the dead band distance between the leading seal edge and the port opening with the piston in a starting position. A lever is pivotably associated with the housing and operatively associated with the piston for moving the piston within the cylinder between the starting and a pressurized position as the lever is actuated between a rest position and an actuated position. A reach adjustment is operatively associated with the lever for varying the rest position of the lever relative to the master cylinder housing independent of movement of the leading seal edge relative to the port as the reach adjustment varies the rest position of the lever.

摘要： A method of adjusting a lever actuated bicycle hydraulic disc brake master cylinder. The disc brake master cylinder has a housing defining a cylinder having first and second ends and a port communicating with a fluid reservoir between the first and second ends. A piston is received in the cylinder and the piston has a seal having a leading seal edge between the piston and the cylinder. The lever is operatively associated with the piston to move the piston from an unactuated position with the leading seal edge a select distance between the port and the first end of the cylinder to an actuated position between the port and the second end of the cylinder. The method of adjusting the lever actuated bicycle hydraulic disc brake master cylinder comprises varying the select distance between the port and leading edge of the seal with the piston in the unactuated position and providing a stop preventing the leading edge of the seal from moving between the port and the second end of the seal as a result of varying the select distance between the port and the leading edge of the seal with the piston in the unactuated position.
