1*So, yep, you may never need brakes at all, if nothing unexpected, or unplanned for, happens..
It's much simpler for the states to set some specific weight, as Texas has done, but way back at least 36 years ago, and I don't know how much longer before that, the federal government recommended requiring trailer brakes on any trailer that weighed more than 40% of the weight of the towing vehicle.So, yep, you may never need brakes at all, if you drive properly, understand the dynamics involved and nothing unexpected, or unplanned for, happens.
