Abstract
A brake/clutch locking system has a brake panel-blocking rod attached to a slidable axial tube in an axial tube to which an anti-lock mechanism is connected. A block in a chamber operatively coupled to a coil spring has a mass that produces more kinetic energy than the coil spring. The block has a shoulder portion with a shape corresponding to a protruding lower edge of a coil spring biased pin that slides into a bored hole provided in the wall of the axial tube and on the slidable axial tube, blocking movement of the slidable axial tube when an external force applied to the block creates a sufficient amount of kinetic energy to move the block from the protruding edge of the pin.
