Brake Bias

[DGamelin]

Does anyone know if the brake bias can be adjusted on a 2022 3500 dully with air ride?

Curious why you want to adjust it.

No you can't as the ABS maxes it out electronically to the point the tires would start to slip.

I want more rear brakes. Because of the wear on the front tires I am going to have to rotate the tires more often then I should have to.

With the air ride load leveing I didn't think it would be adjustable, I figured if you could it would be in the software.

The lack adjustability doesn’t have anything to do with the auto-level. There hasn’t been an adjustable rear bias since long before auto-level.

What’s wearing uneven on the fronts?

DRW’s are known for being hard on front tires.

My 04 and 15 brakes were nothing impressive. This 22 has the brakes these trucks should have had all along, very impressive. I haven't even pulled a heavy load yet, under 18k. When you brake you can feel and hear it peeling on the front tires especially in 100 degree weather. The rear aren't showing any braking chop at all. Nothing like all my other trucks. I rotated the tires at 5500 miles. Every trip is with a new trailer, so the brakes on the trailer aren't seated until I am almost home. This truck has so much brakes it is doing most of the work.
I was just wondering if anyone has dealt with this yet. I don't have time to mess with it. In a few weeks my dodge buddy is going to try to reprogram a few things we will look at this then.
Thanks anyways guys.

Couple things you can do to get better life out of your tires.

Get it aligned to 1/64" toe. When rotating the fronts leave the wheel in it's place and move tires right to left and left to right keeping the rotation the same. This places the outer wear on the inside. Leave the rears alone.

Air pressure is a biggie also. Run 80psi on the fronts ALL the time. Rears I run 30-35psi unloaded and 65 rears when I am running full RAWR. Know your rear axle loaded weight and use the weight inflation chart for your tire and add 5psi to what the chart says.

Close to 60k on these.

"The rear aren't showing any braking chop at all. Nothing like all my other trucks."

This braking "CHOP" you mention is called "STEPPING" on the outer edges caused by too much TOE. Do as I mentioned above and your "CHOPPING" will disappear!!!

Factory TOE setting is 1/4" and is WAYYYYY too much.

Every trip is with a new trailer, so the brakes on the trailer aren't seated until I am almost home. This truck has so much brakes it is doing most of the work.

Experiment with your controller (brake type and gain) to try and get more trailer braking.

The air pressure is good, I usually get around 60k out of a set.

The chopping as we call it is on both the inside and outside of both of the front tires, so NOT a toe in issue, besides it was checked. The tires are wearing evenly, just a lot more than they should. The truck only has 5500 miles on it. I have only made 2 runs with it. It's a brake bias issue. Wasn't interested in an opinion on a grocery gettres alignment.

I have dull brake controllers, so I always have a back up and for pulling tandems. That is all the brakes the trailers have. I buy a new one with every run. The brakes start working good about the time I get home. I have even stopped to adjust the brake shoes on a run.

Just wanted to know if anyone has messed with the brake bias.
Thanks anyway guys.

Didn’t even finish your reply above as you need to learn some manners.

Okay, sorry I am not addressing your brake bias, but I have questions. What are dull brake controllers? Is that after market, not oem? Are you using your Exhaust brake at all times to slow down? What kind of trailers, how heavy/big? You mention tandems...you mean tandem axles or two trailers? Watch this video.
