09 International Brake Lockups


Maybe someone here has some insight on this issue. Our trailer brakes are locking up on us when we come up to a stop light or go slow around corners.
Im not sure but I think it's just one wheel. Do you know if our 09 Airstream international has the self adjusting brakes on all four wheels? Does this sound like a mechanical issue (i've heard of springs failing) or just a setting on my electronic brake controller?

I've made sure the power boost on the brake controller is off and its set pretty low. I think 4.

Any thoughts?

Thanks Tom Marquis

same here

hi- I've had that happen on my '72 occasionally, so I'm guessing it's a brake-controller issue. I've noticed it sometimes getting off the interstate and into a town, at a stoplight- the brakes seem really grabby. I use a Prodigy controller, and like it except for this occasional glitch. Anyone else know what the deal is?

First off have you ever set up the brake controller? After adjusting all the wheels follow the road test. This generally means traveling at 25 mph on a level surface and slamming on the manual controller. If the brakes lock do it again after you have backed off slightly on the controller gain. Keep this up until the brakes do not lock on a hard manual stop. That is the set point for the controller.

If after this set up you have one wheel that you can not keep from skidding that wheel has a mechanical problem.

Keep in mind that if the trailer has auto adjusters you have to hold the adjuster away from the star wheel with a small screwdriver while adjusting the brakes. If not the adjuster will keep the star wheel from moving in one direction, the relaxed direction.

Hi I didn't get the usual email that comes with a reply post. I
assumed the trailer brakes were a sort of set and forget once the dealer installed and set them up. Is this something you do every time you go out? When you say manual stop is that the lever on the controller that activates the breaks independently of the truck breaks? I'll see if I can find the manual online and go through the setup process again. The trailer has been driven across the country and is probably due for a dialing in.

I think self adjusting brakes may have been installed starting in 2010, but it could be earlier, during the model year, or I'm guessing. Guessing may be likely. You can contact Airstream customer relations, have your VIN ready. They should be able to tell you.

I don't understand why self adjusting brakes need to be adjusted except when installing them. Auto and truck self adjusting brakes have been around for decades and they don't get adjusted.
