I am sure I saw somewhere the procedure for setting the brake shoes on a twin axle trailer was slightly different to a single axle. Checking out the Champion trailers site, they suggest adjusting the star nut till you can't move the wheel, then back off 8-10 clicks. If I remember correctly I should back off a different number of clicks for setting up a twin axle. How many, I can't remember... Any help/suggestions appreciated. Thanks
