I guess my question was a little vague. In my case, I have a detailed
inspection of the rig and post crash brake measurements from which I
calculated a braking efficiency. The variable came up when an attorney
asked if I had adjusted for the fact that the truck was empty. In the
calculations it adjusts for the weight on each axle so my answer is yes.
But really that just correlates how much weight to a good brake as opposed
to how much weight on an out of adjustmewnt brake.He seemed to be relying
on a study that sugested an overall lowering of the decel rate when a
specific truck is empty as opposed to when it is loaded. I would be
interested if anyone knew of such a paper.
