sorry, Bill, I'm going to add my next update without being able to address yours, other than to say that in some of the old threads I've found (Bob questioning I think), there seems to be a lot on whether the brakes go back to their cam plates, or whether they remain 'on cam' i.e. are still under tension at pedal. I'm not sure what is actually advised now but that must affect available travel.
I've just been faffing with (rear, uncoupled, standard) brakes to address the levers and I am now unsure, having come away from the car concluding:
1. In order for cotter nuts to face to the back, I'm presuming that makes the levers handed.
2. And that that is the only thing that makes them handed?
3. I can't work out how which way the cotter goes in can get an extra 5 degrees of adjustability, when the angles of the cotter surface is 90 degrees to the lever.
4. there doesn't seem to be much ability to have a "down and in" short lever sitting further back from the vertically down position, as the axle case gets in the way within an 1" of movement?
5. And with two different cams in hand to try, I couldn't do anything better than get the lever pointing absolutely vertically down when the shoes are wholly back in their cams, whereas I really wanted it right back on the axle to allow take up of slack on actuation.
Have I overlooked something really major? As it is, I'm now thinking that the shoes need to be absolutely finely adjusted in order to make use of the vertical downward lever position... but I can't imagine how that could be maintained as they wear without reshimming?
