  • Is it normal for a new 22MLE to only have ONE self-adjusting brake?

    Hello All,

    I noticed that I had little to no braking authority on my brand new 2023 XLS 22MLE (gain of 10 barely slowed me down), so I figured I'd adjust the brakes. As I started around, all of the brakes were well out of adjustment (which I expected), and all were manual-adjustment type brakes. However, the last wheel (Passenger front) had a forward self-adjusting brake kit on it. (It needed to be adjusted as well.) But I thought it odd that only one of the wheels had self-adjusting brakes, whereas the other three were manual.

    Has anyone else run into this?

    Hailing from central Utah, this is our fourth RV, but our 2023 XLS 22MLE is our first Travel Trailer. We've been very impressed with the GD build quality. Over the years, I've rebuilt every major system in RV's, added solar components and inverters, and perform all of my maintenance.

    Hi Melsman,

    ​​​​​​Welcome to our owners technical forum. Have a look at our welcome post. https://gdrvowners.com/forum/main-fo...to-new-members . This will help you set up your signature and navigate the forum.

    As you would expect . . . all brakes would normally be either manual adjusted or auto adjusted. Is it possible that the auto adjusters are out of position on the brakes that appear to be only manually adjusted? This would be difficult to see through the adjuster hole . . . you would probably have to pull the hubs.

      I agree with Rob, the auto adjusters may be hard to see, or they may have become dislodged during a braking event due to the mis adjustment.

      On Mine (never ran over 5.5 on the GM brake gain) the adjusters were up and out of the way. I believe to tighten (make the shoe closer to the drum) the adjuster needed to go down down on the adjuster wheel instead of up to decrease clearance (up on the brake spoon vs down as I recall on automobiles).

        Trailer adjusters are “backwards” because they adjust going forward whereas the old car/truck adjuster worked when backing up.

          Thanks for replying Rob - Yes; I confirmed that the other three were manual. As Joseph mentioned above, the adjuster "teeth" are different between the manual and adjusting brake types, and move in opposite directions to tighten. I also pulled one of the other hubs because I was confused by what I was seeing!

            That means a call to Dexter. Have both axle serial numbers in hand when you call. Both ends should be the same per axle at least.

              Thanks, Joseph. I probably should have mentioned they were Lippert axles, but it appears that the situation warrants a phone call nonetheless. I was just curious if there was a reason for only having one self-adjusting brake on a dual-axle trailer.

                This has to be a manufacturing oversight. I would call GDRV at 574-825-9679 with your VIN and axle serial numbers to discuss.

                    I think it might be a federal law, but trailers over a certain weight in Texas must have brakes. Any MFG should not be mixing self adjusting and non self adjusting component on one axle let along on a system of axles. That's a recipe for a disaster as if you check only the one self adjusting one, you get a false sense of security. In today's world, that leads to lawyers.

                        As a follow-up…

                        I did verify without a doubt that one of the four hubs was auto adjusting; the other 3 were manual. (With indisputable photographic evidence.) I sent an email to both GD and Lippert (after a poor experience with the call in line) and Lippert is sending me a conversion kit free of charge. I emphasized with both of them that such an oversight could be dangerous and that they need to address such a possibility through their individual QA processes. Neither commented on this latter point (which given the litigious nature of our society does not surprise me), I can only hope that they will incorporate some sort of quick check to keep this from happening again.

                          Dexter did have an axle recall because someone forgot to install races in the hubs. It's manufacturing, things happen, and if I had to guess, the right side of the assembly line does not know what the left side is doing. As the parts roll down the chain, if one gets rejected and no one pays attention, things get out of sync.

                            Are you saying they have a kit that will convert an auto-adjusting brake to manual adjusting? If so, I'd really appreciate your letting me know the part number when it arrives.

                            GD was very kind to send me a replacement drum and brake assembly after my warranty expired. The brake assembly was incorrectly sent as auto-adjusting. I needed the drum worse than the brake assembly, and was fortunate to already have a manual brake assembly available so I did not complain. It would be great to be able to convert it to manual.

                              I would think that if you removed the pull cable . . . you would remove the self adjusting feature.
