I have a Bighorn 3570RS and recently decided I was going to upgrade the brakes to the Titan disc brake package. We tow our Bighorn with a 2018 Chevy 3500 SRW. I did the conversion myself and was pleased with the quality of the components and ease of installation. We took the rig out for the first time today to test and evaluate the upgrade. The brakes seem to work very well and are definitely much better than the OEM brakes. The question I have is should I be able to lock up the brakes when testing and adjusting the brake controller? I have several friends that indicate they can lock up the brakes on theirs, but they're using an outboard brake controller. I think my new disc brakes are working normally, but not sure. If my understanding of the integrated brake controller on the new Chevy trucks is correct, the brake control voltage is proportional to the speed and braking of the truck. In fact there is no braking control voltage from the truck until the truck is in motion. I wonder if any of you guys have a new Chevy with Titan disc brakes can enlighten me on how yours work. Btw, i have my brake controller set on 9 which seems to be about right.
