Abstract
A control device such as a handlebar-mounted brake includes a support structure containing a hydraulic piston, a lever pivotally connected to the support structure by a pin, and a transmission element for transmitting force from the lever to the piston during a normal actuation stroke of the lever. The lever may pivot outward substantially beyond its normal rest position. A torsion spring biases the lever in the actuation direction so that the lever and the transmission element are normally in contact. However, in the event of a fall, the lever can pivot outward from its normal rest position, out of contact with the transmission element. The hydraulic components are thereby protected from damage, as the pin and support structure bear the entire impact force applied to the lever.
