Re: [Amc-list] brake drums

[farna@xxxxxxx]

It should be possible to interchange front and rear drums of the same thickness. Front drums come off the hubs -- drive the studs out (get new ones to put back in!) then press/knock the drum off the center hub. The center hole in the drum should be a snug fit on the front hub, but should work even if it's loose like a rear drum. It can't be to loose or it won't center correctly on the brake shoes though. 

Overhanging the backing plate will be a problem. The backing plate has a turned in lip that fits inside a groove on the drum -- at least all I recall seeing do. The lip could be cut off the backing plate, reducing the diameter enough that it will fit inside a slightly wider drum. That should provide just about as much "seal" as the lip and groove -- enough to keep most water and such out. Since most people only drive their AMCs in good weather the affect should be minimal. Just be a bit more careful in wet weather as more moisture could get in the brakes, reducing their effectiveness slightly.

I got the drums  from NAPA today and they are REAR drums (no place for wheel 
bearings). So the rear drums are 640-1074 that look like they will be a good 
replacement even though they are  2.5 inches wide. They will overhang the 
backing plate but I don't think that will be a problem. More later.
