Abstract: An anti-theft apparatus for a vehicle having a vehicle floor, a vehicle fire wall, an accelerator pedal, and a brake pedal mounted on a downwardly extending brake pedal lever, includes a cradle for fitting around the brake lever and including structure for retaining the brake pedal against substantial lateral and downward movement relative to the cradle, a bracing portion connected to the cradle and including a leg and a foot mounted to extend downwardly relative to the cradle to abut the vehicle floor for preventing removal of the cradle from the brake lever and brake pedal, and for preventing depression of the brake pedal and brake lever to operate the vehicle by bracing the cradle against substantial movement relative to the fire wall and floor, and a lock mechanism for releasably securing the leg at the given extension relative to the cradle that the foot abuts the vehicle floor. The cradle bottom wall is preferably concavely arched to follow and receive a forwardly curved brake lever.
