US Patent 9399448 Towed vehicle brake actuation apparatus

A brake actuation apparatus and method are described. An air cylinder is pivotally attached to an operating unit of the brake actuation apparatus. The air cylinder extends away from the operating unit and is configured to connect to the brake pedal to actuate a brake of the towed vehicle through the brake pedal. A stabilizing cable has one end attached to the firewall of the towed vehicle and an opposite end releaseably attached to the brake actuation apparatus, such that when the air cylinder applies pressure to the towed vehicle's brake pedal, the stabilizer cable transfers reaction to the towed vehicle's firewall and supplies a stable anchor point.
