Chevy's IBC (integrated brake controller) setup question

With the IBC there is no 'grab' as with an aftermarket controller. It is totally proportional to the brake pressure on the brake pedal and integrated with the ABS of the truck. When I first got mine I too wondered if this thing is working, but it is so smooth you will not notice the grab. You will get used to it.

My new 5th wheel has "self-adjusting" brakes. Does that mean they can't be manually adjusted?

If any brake controller setting in insufficient after following the owners manual's adjustment procedure, then adjust the brakes on the trailer.

My '08 GMC IBC is set at 7 and the new fiver stops great. My old fiver I had the IBC maxed out. Remember these don't have the same stopping feeling as the after market do. These are designed to feel as one whole unit and you won't generally feel the trailer grab. Make sure you are in tow haul mode and you will use a lot less brakes as the Allison is awesome at slowing the rig down. Take it out, get up to speed and try some hard braking to get the feel on how it works. I love the IBC on the new trucks.

It does seem to work but if it's not suppose to grab like the aftermarket stuff then it might be ok. I just don't like it maxed out and I haven't loaded anything in the camper including water!! I'm going to try to tighten the brakes up at each wheel, I have been told to tighten then then just back off till the wheel turns freely, not 8 clicks. I'll give that a try. I have also been told that the brake controller is "adaptive" and will have to be backed off later as it will get better, any truth to this??.....

Check to see if you have a trailer type selection. My (Ram) IBC has a setting in the menus to select if the trailer is light ( under 7500 lbs) or heavy ( over 7500 lbs), in addition to the power level setting.

edit: forum didn't like my use of greater or less than symbols

I've never been able to get the same performance out of the IBC than an aftermarket unit. My 13 had to be at 8 as opposed to 4.5 on my Prodigy. Now my 15 is at 10. It grabs fairly good and is adequate, but it IS turned all the way up.
