Yes, don’t folks put extra brakes onto they system (not sure how, but) I thought there were extra trailer brakes, plus extra brakes on the truck when you did a hitch. I wouldn’t rely just on the regular car brakes when hauling. The other things which really help is a heavy duty transmission which can take the wear (besides the engine) and heavy duty fram/axels which can take the torque. That’s just off the top of mty head and I am not the expert at all, but its what I THOUGHT you were supposed to do to accomodate hauling live load up and down hills and distances.[/QUOTE]
In most states, any trailer over a certain weight need to have brakes. I could be wrong, but horse trailers should be over that weight in almost every single state.
There are not “extra” brakes anywhere, but the truck has brakes, and then the trailer has brakes. The trailer brakes are activated by a signal from the truck (through the brake controller). The truck should not be stopping the trailer, and the trailer should not be stopping the truck. There is an art to adjusting the brake controller correctly.
By “heavy duty transmission” I assume you are thinking of a “transmission cooler”. To upgrade a transmission for towing is about a $4k job. :lol: Most transmissions in any vehicle MEANT for towing (not that can tow, but MEANT for towing) should be adequate, and are helped out by the addition of a transmission cooler. Any legitimate “tow package” (some places will call a “tow package” the addition of a 7-pin plug on the back :lol:) should come with a transmission cooler.
