There was a good article in the Motorhome magazine a few months ago explaining tow braking systems. There are many systems available, and from personal experience they are worthwhile. I use the ReadyBrake, requires instillation in the car but makes hitching and unhitching very simple. I previously had the BuddyBrake box, which you place at the foot of the drivers seat. Worked well, but you need a place to store it when not in use. Most RV dealers, and Camping World have displays explaining at least a few of the systems available.
