I finally have my 62 Airflyte completely disassembled and the frame is now at the sandblaster getting cleaned up, primed and and repainted. To my surprise the 10" x 2 1/2" brakes and drums are in extremely good condition with only a light dusting of rust in the drums. With a little scrub I think I can use them exactly as they are however I would like to test the magnets under power. I read on another post that they can be tested with a battery charger but I don't understand how that would work. Is there an accurate way to test the magnets either on the hubs or on the bench? Also I assume there is a resistance range they should measure on the OHM meter but aside from them being equal to each other is there a recommended resistance value? Any advice would be appreciated.

I’m not nearly as technical as you. I just used a lawnmower battery and tested mine by spinning them and hitting the brake post in then7 way box with 12v from a lawnmower battery.

Thanks Adderall. I seem to have found what I was looking for. I found an article on etrailer.com that states that each magnet should draw 3.2 to 4 amps when hooked to a battery providing 12 to 13 volts and the resistance across the terminals should be 3.0 to 3.8 Ohms. These specifications are for modern electric brake magnets however I'm assuming the vintage ones should at least be in the same ballpark considering it appears the technology hasn't really changed very much.

Off subject, I love your photo of the camper on the raft. I remember your intro story. One of a kind.
