Hi



It sounds like you just didn’t manage your descent.

You should have started down at about 45 Mph. Then at 50 Mph apply brakes as needed to get back down to 45 Mph. Us a fair amount of braking to bring the speed down this gives you a short time period during the brake heat up and a longer time period before brakes are needed again.

As for the aftermarket brake controller that has been a thought that I have had but never did do it.

The GM OEM controller will not lock the trailer brakes even when set to 10 and applied by hand to full scale on the graph.

You can check the trailer brakes in the manner I described to make sure the trailer brakes are working properly. Be aware the person in the bed of the truck must be ready for rapid deceleration. Don’t leave the emergency brake pin out for any length of time that will damage the magnets that apply the brakes. I would suggest disconnecting the trailer battery and pull that pin and put it back in a couple of times so you can see how to get it back in without delay.
