Many of the present day aftermarket relined shoes are reconditioned with long linings on all shoes. Originally the factory shoes had a long (Primary) and a short (Secondary) lining. There are still quality shoes on the present market that still subscribe to the long and short primary and secondary linings. The shoes with long linings are installed facing toward the front of the Jeep and the short shoe is installed facing the rear. (As instructed in the manual for a reason). This is done the same on all four backing plates.
Factory paint on the inside of the backing plates is found both in lusterless OD and Red Oxide color paint. I have seen examples over the past 60 years or so of either on the MB/GPW. Gov't rebuilt axles I have seen over the same period have been repainted mostly Red Oxide color (on the inside), and on some, Red Glyptal type paint such as found inside electric motors . I use the Red Glyptal Insulating paint that I purchase in aerosol cans from a nearby electric motor rebuilding service as it goes on with a hard glossy red surface that is easy to wipe clean and it dries in just minutes.
It is always good practice to apply a touch of grease (old time Jeep mechanics used Lubriplate 630AA) on the surface of the brake adjusting excentrics, the raised areas on the side of the backing plates and on the brass cams for the anchor pins. This will ensure smooth quiet brake shoe operation.
