Abstract
An early braking system for a vehicle having wheels comprising, a friction element, a brake pedal and a sensor. The friction element inhibits rotation of the wheels of the vehicle with the braking system having a dormant state wherein the friction element is at a first position spaced a first distance from the wheels. The brake pedal is adapted to be depressed to move the friction element into engagement with a portion of the wheels of the vehicle. The sensor senses an operational parameter of the vehicle. The friction element moves from the first position to a second position spaced a second distance from the wheels in response to a predetermined measurement of the operational parameter and before depression of the brake pedal, wherein the second position is closer to the wheels than the first position.
