Carrier Brake problems

[rob love]

The inner wheel seal (The one that is on the innermost part of the drum) is a commercial seal still produced today. It was used on many Ford chassis.

The outer wheel seal (the one that goes with the bearing adjusting nuts) has not been produced for many years. It's job was to keep the oil from entering in with the grease.
Many guys simply toss these out nowadays. Personally, I bend the lip of the leather part out so it will make a bit better contact and reuse them.
The oil mixed in with the grease is a great lubricant, but where the problem will come in is if the hub gets too full it may leak past the inner seal and onto the brake shoes. The origional seals had an oil slinger to direct any oil leaking past out a little pee hole in the back pate of the brakes. This hole is usually filled with mud, so it doesn't work so well.

No offense taken with regard to the turning of the drums. Everything must be done to moderation. But no amount of sanding will replace the braking effort achieved by having a set of drum surfaces round and smooth. Since the manuals do not give a drum diameter, I had always believed the army merely replaced the drums instead of turning them. 30 or 40 thou off, with the shoes suitably mated, won't hurt anything. Since the carrier is now less likely to ever see the abuse that it had when it was in service, I would almost bet this will be the last brake job done for a few decades.

Has anyone measured canadian carrier drums and compared to see if the drums were omre or less a standard size, or if the army turned them?
