What does braked towing capacity mean?

When the manufacturer states that a towing capacity is "braked" they are referring to brakes being fitted to the trailer that the car is towing.

At least one of the axles on the trailer that the vehicle is towing must have brakes fitted and controlled by the car if they describe the capacity as "braked".
