Hi
I have a 2009 2500hd duramax
I have some trailer brake problem. When I hoockup my 15 000 lbs trailer with electric brake I can barely feel the braking of the trailer when I used the manual testing switch on board. My friend took the trailer for brake service with his f250 and even if he is at 7 out of 10 range calibration the trailer was braking the truck. mine setup at 10/10 on the gauge can barely slow the Wheel.
any idea of what you be the problem with my truck.
doesn't seem to be the trailer the problem has it works perfectly on a ford truck
Thanks
