Forgive me if I have not posted this in the right place but I have a quick question. Say if you have a trailer on a truck, let's say a semi trailer, that has 2 axles on it. You measure the stopping distance from a certain speed. You then add another axle to the trailer that has brakes on it with no additional weight on the trailer other than the few 100lbs that the axle itself weighs and test it again from the same speed in the same conditions. If assuming the brakes are fully capable of locking up the tires regardless of the weight on them, will the 2 or 3 axle trailer stop quicker? Basically I am asking if the extra axle helping stop will stop quicker or will the extra axle taking weight away from the original 2 axles make them not able to help stop as much resulting to the same stopping distance or maybe even less due to the extra weight of the 3rd axle?
