why wouldnt it matter if the road was icy/wet?
your braking ability is only as good as your traction allows
simple minded fool.
Thats what I am saying you nut snacker
These auto brakes wouldn't matter if the roads are slippery because there would be alot less traction
and the trailers have dual heavy duty shocks in between the cab and trailer just in case the truck brakes hard
but I don't know how much they can stand
