Brake magnet scoring drum

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.
