I forgot to adjust my brakes last season so I called Dexter Axle to see if the brakes were self adjusting or manually adjusting. It appears GD uses both so to make sure I made a quick phone call and spoke to the Parts Dept: 1-574-295-7888.

I gave them the serial# that can be found on the axle or on the Serial Number Data Sheet that should come with the unit. Ours are manually adjusting.

Here’s a quick 2:42 YouTube explaining how to adjust them if you want to do it yourself and haven’t done it before. Since it’s pretty straight forward I’ve always done mine in our driveway.

Instead of jacking the trailer as shown in the video, I use a Trailer-Aid Plus. It lifts the tire enough to spin it. From what I’ve read it doesn’t work for all trailers. I carry it while we travel in case of a flat.
