Good thread and GREAT commentary on the laws of physics
Braking is MORE important to me, than go...though go is ingrained in
this wrench/gearhead/boy-racer...
Why advise that trailer brake controllers must be tuned to lead the
TV's braking (in timing...initiation)
Posted this before and many do NOT believe that braking is a performance
rating...that it is a mandated requirement by specification...by regulatory
agencies (FMVSS). Mostly for commercial, but they also for civilian vehicles
Here is an image showing them all side by side from a vendor's site
marketing that their friction materials better

My TV's brakes are in the performance level and out stop some cars when
empty (just me in it). So look in the rear-view as much as ahead at
what am trying to avoid
Why advise touching the trailer brakes every once in a while (often)
to keep them in their optimum temp range...and...re-adjust during
long trips
