I assumne these are pics of the the old brakes you replaced? There does seem to be quite a bit of wear on these. The wheel mounting studs should be recessed in the hub/drum but it looks like either they weren't recessed enough or the steel surface has been worn down till they are starting to get wear from the magnet.
Do the wheels turn freely now with the brake controller on but no braking activated? |

At the moment, brake units, hubs and bearings are new. Wheels turn about a complete revolution before stopping. Burnishing is not completed yet but drove about 20 miles with everything new and braking seems to be equal on both wheels. On a side note, my part time mechanic worked on RV's ad a dealership for quite a few years and helped me with the problem. He said that when you burnish new brakes, they need an initial adjustment that prevents the wheel from turning no more that one half turn. When I called Lippert, they said the wheel should spin with just a slight resistance and you could hear a small amount of contact to start the burnishing process with.

Lippert has it right. When you initially set up drum brakes (on any vehicle) that is how we adjusted them back in the day, just a sight drag. You do need to engage them a couple of times while spinning the when when adjusting them to be sure the brake shoes are centered up on the drum.
