Most trailers now come with brakes
, however that was not so in the past. As long as the axle
has the brake flanges, you can add the brakes later (The brake flange is a square piece of metal inside of the wheel with four holes drilled through it).
Why brakes? It really does make a difference in stopping -- I was pulling my 13' Scamp
with a 1/2 ton Dodge pickup and the before and after was quite a change.
Ford adds this note "The vehicle brakes are designed to stop the GVWR, not the GCWR", which means "stop the tow vehicle but not the towed vehicle".
Also, six braked wheels on the ground is clearly better that only four!
