adjusting integrated brake controller to 5er

[asquared]

I just bought a 2014 sabre 34REQS-6 5er on Saturday. I have a 2014 chevy Silverado 3500 duramax with the factory integrated brake controller. As soon as I hooked up I worked on getting the controller adjusted. I would accelerate to 25mph and hit the slide brake control to activate the tt brakes. I never was able to achieve lock up even with the controller set to 10 (max). I definitely felt the brakes grab and slow the truck and trailer down as low as 6-6.5 but never found a lock up point. I left it at 6.5 for the ride home and never felt pushed by the trailer but did feel periodic grab/jerking from the brakes.

Is there a break in I need to be doing for the trailer brakes? Am I adjusting something incorrectly? Is it related to the weight of the 5er? This is the way I adjusted it with my old tt on both this truck and my old truck. No problems then. One thing of importance. The dealership installed my fifth wheel hitch and plug. DH said the voltmeter read a little over 12 out the plug in the bed of the truck. Any advice? Thanks.

They actually may need adjusted a little bit.
I run mine at 7 - 7.5

Ok now for the really dumb question. How do you adjust the brakes?

Anaro its under WARRANTY please make them do it.

I'd check the truck manual.
I think your truck learns and it may take some miles.

I manually burnish new shoes. It says to do it in the instructions.

Yeah I know, just losing the time of taking it in and letting them play with it had me thinking if we could do it we would. They have been taking good care of us there but they don't really have service techs there on weekends and getting weekdays of is dang near impossible for us.

It is fairly simple to adjust the brakes if you have the time and tools.
Youtube.com has some pretty good videos to help you.

Thanks, I will spend some time there.
