Abstract
Brake lock detection is described for a brake activation system. In one example, a main housing is configured to engage an interior surface of a towed vehicle near a brake pedal of the towed vehicle. An actuation arm extends away from the main housing configured to connect to the brake pedal to actuate a brake of the towed vehicle through the brake pedal. An arm drive system of the main housing applies a positive pressure to the actuation arm when activated to drive the brake pedal to actuate the brake. A negative pressure sensor generates a negative pressure signal when the brake pedal applies a negative pressure opposite the positive pressure to the actuation arm and the actuation arm is not activated.
