Exhaust Brake

[Luna18]

We had a great summer of travels in 2017, spending 42 days in our new 5th wheel. We purchased a 2015 Cedar Creek 38FB2 5th wheel....its 42 ft long.
We are pulling with a 2015 Chevy Silverado 3500 Dully Duramax Diesel with Allision and exhaust brake.

We had no trouble stopping.

Curious how you set your exhaust brake ???? 1..2..3..4..5..6..7 How do you know when it is set properly?? and pulling its weight stopping.
We have had no close calls stopping..but who knows.

Thanks

I use my exhaust all the time even with out the trailer. As for trailer brakes I have mine set at 5. And that exhaust brake on my 17 will keep my truck at one speed going thru the hills of virgina. We do a lot of trips to Bristol and Richmond.

Going about 20 mph, apply the brakes with the switch on your unit but not putting your foot on the truck brakes , does the trailer come to a smooth stop without skidding the tires in about 20 yds. If yes, then job done. If trailer brakes lock up and skid before you stop, lessen the setting 5.0 to 4.0 etc. If your trailer doesen't feel like it is stopping with the 20 yards the up the setting to 5.5 etc. Just takes a little trial and error.

I used this procedure 3 years ago when we got our rig. Could never get the tires to skid even when set at 10 so I left it set to 10. Seems to stop OK, but would have been more confident that it was set correctly if I could have achieved a skid then backed it down. Anyone else experience this?

I would take the trailer to a tire store like Les Schwab. Have them pull all the wheels to check all the bearings, that the brake pads are clean and have no grease on them. Then have them adjust the trailer brakes on each wheel. Also have your RV shop check to make sure the exhaust valve is fully opening and closing. I normally set my trailer brakes around 5.0. I have 3 additional settings "1,2,3" . Each provides stronger braking with #3 being the strongest. I use this if I know I am going to be going down some steep mountains.

I have taken my trailer to Les Schwab every 12 months since buying it 3 years ago. Each time they inspect and repack the wheel bearings, inspect and adjust the brakes, and rotate the tires. And I have been using a setting of 10 since Day 1.

Why do you recommend having the EB checked at my "RV shop"? I think the Chevy dealer would be a better place; however, I am super happy with the performance of the EB. And I am actually NOT unhappy with the braking of my trailer. I am just curious if I am the only one who uses a setting of 10.

I leave my EB on all the time. Helps in saving brake wear even when driving just around down.

Speaking of exhaust brake....I have a 2013 2500HD Duramax and the exhaust brake does little to nothing, at least that I can notice. My dealer says it's normal that if there were a problem, it would trip a code. I pull a 5th wheel and was a little disappointed with the exhaust brake. It really doesn't seem to do much. The only thing I notice is that it might downshift a little more with it on.
I set my trailer brakes at 4.5. I think the trailer brakes should be an "assist" rather than do the most of the braking on my rig.

When you are going down a hill, open and close the exhaust brake valve. While coasting down the hill turn the EB on and off and you feel the EB slowing you down and then when off you should feel like you are coasting and the truck will continue to pick up down hill speed. If there is no difference, take the truck into the shop to make sure the EB is fully opening and closing.

I've got a 2016 Duramax. I think you are confusing the exhaust brake with the intregated trailer brake system. Exhuast brakes are either on or off. The trailer brake to your left can be adjusted by numbers. I would suggest putting it at about 4.5 and see if the RV brakes even with the truck then adjust from there.

You lose me. There is no setting for the Exhaust Brake on my previous 2011 or current 2018 Duramax, Exhaust Brake is either On or Off.
Are you talking about the setting for the integrated Brake Controller, as that does go from zero to ten??

[azdryheat]

I have the same truck but it's a 2013. The exhaust brake is either off or on. I turn mine on.
