been seeing that chevy's integrated brake controller won't work with disc brakes on trailer, (eoh setting) but can't find anything that confirms it. anybody have real experience whether true or not?
From the 2500/3500 Manual "The vehicle may have an Integrated Trailer Brake Control (ITBC) system for use with electric trailer brakes or most electric over hydraulic trailer brake systems. These instructions apply to both types of electric trailer brakes."
