Brakes needed for car tow dolly and Mini Cooper?

If towing on a dolly you do NOT WANT TO USE a brake buddy or any other type of aux brakes on the VEHICLE itself. Only brakes on the dolly..

If the Mini's brakes activate while towing it can tear it right off the dolly.

Beyond that I have not real comment.. But when dolly towing do not use the car's brakes.. Dolly brakes (if dolly is designed for it) are OK (it will have some kind of "Stop" to insure the car does nto overrun if the dolly brakes)
