I have had two Prodigy's and couldn't break either and if I can't break it, it can't be broken...

I also had a hidden Hitch on my Element. Hitches are not something to get real excited about.. they go on and you rarely think about them after that, but fwiw, I was happy with it and the price + service I got from Etrailer..

Guess they both are pretty OK.

I tend to agree with Byron about the Jordan and its pedal-position approach. In addition, the changes in pedal height with engine vacuum (assuming the power-assisted brakes that everyone has in this century) are as large as the motions of normal brake activation, so I am not at all convinced that the pedal position is a good indication of the desired braking effort.

Having said that, there is one advantage to responding to driver action (pedal position or pressure) rather than acceleration: descending a hill at steady speed, these systems will apply the trailer brakes, even though an acceleration-based system might see no acceleration to trigger brake application.

I would be happier with brake system hydraulic pressure, like the Ford system, but Jordan users certainly do report satisfaction with the product.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

Pedal position is really quite variable depending on temperature and effects like pumping. Vehicles with drum brakes tend to have a check valve at the master cylinder so that when you give them a pump, the fluid doesn't have a chance to evacuate the slave cylinders and you get to add more fluid to them on subsequent pumps. This means on your first pump, you could be much closer to the floor than on a second and subsequent pump... Also, the emergency brake has no input into the 'pedal height' equation.

I've never used a trailer brake system before but the pedal-height thing seems like a horrible kludge.
