Now you can stop the vehicle your Heavy Duty truck is towing by simply attaching the Brake Buddy® to the brake pedal of the vehicle in tow. When you apply the brakes, the air hoses from your Heavy Duty tow truck engage the brakes of the vehicle you are towing. Yes, it’s that simple and it works! Brake Buddy® extends the life of your brakes, reduces accidents and helps you stop in a shorter distance.*Please Note: The Brake Buddy System should be used in conjunction with a Steering Wheel Lock to keep the wheel of the towed vehicle from turning during transport.
