My mechanic just called with a question about my trailer.
Apparently only the brakes on one of the axils is hooked
up. This brings up the question, "Are both supposed to be hooked
up?"
If the brakes lock on all four wheels the trailer will fish-
tail around. With only one set hooked up, if they lock the trailer
will continue to follow the truck because the other set of wheels
are rolling.
I'm inclined to think both should be hooked up. I haven't had
a wheel locking problem in the past, and my guess is that they
were all hooked up at one time.
Any one out there want put in their two cents?

Many trailers only have one axle with brakes, the other axle is
not a true axle but is a "stub axle". The condition you describe
with two wheels turning and two stopping will have little or no
effect on how much the trailer fish tails. If I remember back to
Physics 101 (ughh it hurts) the real problem is inertial imbalance.
Without getting too technical, if the inertial difference of the
two vehicles is greater than the coefficient of friction of the
driven vehicle then the combination will follow the vector of the
vehicle with highest inertia. Stated simply, you will go in the
direction of the heaviest and fastest of the vehicles. That means
if you can't brake the trailer faster than you can brake the truck
pulling it then you will jacknife at the point where you overcome
the traction of the truck. Thats why tractor trailers jacknife
in the snow. The bottom line is put as many brakes as you can in
the trailer cause you will need them. In any case, you can adjust
the trailer brakes (assuming they are electric).

It's best to have two pair of brakes than one pair. Especially with
the move weight of horses inside, etc. . Not to often you get two
sets of brakes.
