I'm finally re-assembling the rear-end after a complete overhaul. One thing I didn't pay attention to is the brake cam. I noticed the new ones have one side slightly large than the other. does that go towards the axle or not? And how does the cam lever go on. I did take pictures before taking it all apart but not close enough to tell. Anyone have a pic of the correct assembly?
thank you very much.
Is it the small drum axle from the speedster in your profile? In that case I don't know much, I think they look symmetrical on the cam side - may be a LH and RH version depending on the hole for the pin securing the brake arm. Check so the brake arm can be positioned upwards, slightly rearwards when the brake isn't actuated.

I've got large drum brakes myself, they indeed have an eccentric cam, the large part goes outwards and there is a LH and RH version of the cam with the holes for the brake arm rivet pin being drilled at different angles :

There is a left and right hand cam if you purchased new small drum ones. As you can see from Rodgers ((Chris Brancaccio photo) the lever points back.
The holes in the cam's shaft determine which side goes where.
If you have new shoes check that they clear the drums and you can turn the wheel with the brake off. The ones I got were out so far I had to move the cut outs which go around the rear bolt as they put the shoes too far forward.
Now I see there are accessory brake shoes of some kind on the small drum axle in the top photo. Originally it was one piece cast iron, nowadays there are one piece repro cast iron shoes with lining available:
The cams are the ones from snyders. Well one is anyway there were out of stock on the other. I think I should be able to figure it with those pics. Thank you very much.
I'm waiting on a pair of cams also.
