The law is very clear on this, anything being towed over 750kg has to have a braking system or its illegal! a towing dolly with a braking system where the front wheels of the towed vehicle are lifted is your best bet but very expensive. the police are really starting to come down hard on bad towing practices at the mo. Honeyfield trailer centre (Bristol 01179 637231/Gloucester 01452 423871) can help with advice or trailers and dollys.
