Abstract: A parking brake control assembly for a motor vehicle is provided which includes a housing, a movable actuator disposed in the housing which is operable to apply or release parking brakes, and an actuator spring pivotably mounted in the housing. The actuator spring pivots in response to the movement of the movable actuator. A portion of the actuator spring is biased to a first position by a predetermined force, and if the force applied on the portion exceeds the predetermined force, the portion moves to a second position. The housing also houses a switch actuatable by movement of the movable actuator for indicating desired position of the parking brakes, and a piston in fluid communication with a source of fluid. The piston is positioned adjacent the portion of the actuator spring, and the piston is movable by the pivoting movement of the actuator spring to cause fluid to be ejected such that the ejected fluid indicates desired position of the parking brakes.

Abstract: ESTOP is a braking device causing a motorized vehicle, such as a snowmobile or ATV, to stop when the driver is ejected. When the ESTOP is armed, with a trigger pin attached by a tether and clip to a driver, the vehicle braking system functions normally. When the driver is ejected, removing the trigger pin, the ESTOP, unarmed, releases a force applying pressure, mechanically or hydraulically, to brake pads stopping the vehicle's brake rotor and bringing the vehicle to rest. Mechanically, ESTOP applies pressure from a released spring to brake pads on a caliper mounted on the vehicle's brake rotor. Hydraulically, the ESTOP applies pressure from a released spring to the vehicle's hydraulic brake system through a secondary master cylinder. ESTOP potential energy is not limited to a coiled wire spring, but may include a compressed gas canister, engine provided vacuum or an electrical solenoid.
