sorry you misunderstood me...my question was if I buy a new set of 10" brake assemblies, can I use my old 10" drums or should I replace them with new 10" drums? is there a min/max dia to adhere to?

Hi, most, if not all drums have a cast-in mark or stamped, stating the maximum diameter. Usually .060 would be the max, sometimes .090 and your drum should have a marking on it like "10.060" or similar.

Unless you have tons of miles on the original drums, they will be just fine with the new brakes.

Make sure, however, that you adjust the new brakes to fit the old drums.

From reading this thread, I'm assuming that my '06 22ft. Safari does not have self adjusting brakes even though they appear to be Dexters. I have'nt backed it up for self adjusting purposes but have manually adjusted them when I noticed they were not activating as when newer. I have 5/32's of lining left on apparently bonded linings. How long until new linings are needed?
Thanks a bunch! Billie Bob

Welcome to the forums. If you have 5/32" left, you should think about replacing them when they get to 3/32". Depending on how much you tow, probably next Spring would be the time.

12" Drums

Can I buy 12" drums for my '74 Argosy 26? Will they fit my rims? I'm assuming they are the original wheels.

I believe you have 10 inch drums.

What size wheels do you have? Are they 5 lug or 6 lug?

You may already have 12" drums on your trailer. Check where the backing plate bolts to the axle spindle. If there are 5 mounting bolts, you have 12" brakes. If there are 4, you have 10" brakes.

Rims

They are 6 lug. So I'm guessing they are 12" rims. Should pull rim off and measure it. But 6 lug sounds like 12" drums.

Nope.

Both 10 and 12 inch brake can use 6 lug wheels.

No need to remove anything.

Look at the backside of the brakes.

There is a plate that the brakes mount to.

If that plate is square, and has 4 bolts, the brakes are 10 inch.

If that plate is round, and has 5 bolts, the brakes are 12 inch.

Argosy trailers back then used 10 inch brakes.

But, things being things, it's wise to make sure.

Never say never

I owned three Argosy trailers that had 12" brakes. In fact, every Argosy trailer I've worked on had 12" brakes.

Brakes.

Some Argosy owners luck out with 12 inch brakes. They may buy a used Argosy that has been updated.

On the other hand, some used Airstream trailers that were built with 12 inch brakes, now have 10 inch brakes, due to down grading. In the opinion of some, 10 inch brakes stop just as well as 12 inch brakes.

Both the 1974 and 1977 "ARGOSY" parts book, specifiy 10 inch brakes, except for the 20 foot model.

Of course, Airstream could always be wrong.

Unfortunately, 10 inch brakes, perfectly adjusted, have a stopping power of 3500 pounds, per axle. On the other hand, the 12 inch brakes, perfectly adjusted, have a stopping power of 6000 pounds per axle. To some, or so it seems, the additional stopping power of 2500 pounds per axle, with the 12 inch brakes, is insignificant.

If I was towing a 29 or 31 foot trailer, and the brakes went out on the tow vehicle, I would change a few colors if I was dependent on a maximum of 7000 pounds brakes stopping 12,000 pounds of equipment. But, perhaps I regard safety higher than some.
