Hi,
I'm late to this, so probably you have figured out the problem. If so, I'm curious. I was having a similar problem (minus the brake issue) last year, where the car was rough and cutting out sometimes when I came to a full stop. It improved after I had the choke adjusted (also following a cold snap after a hot summer) and got a new set of points, plus condenser and coil. Recently, a year later, the roughness started again, and the cutting out. Again the quick fix was adjusting the points, which had got so that they were barely opening. So now my car is running well, though I think there's a more deep-seated problem, because something is causing the points to tighten up and wear out/burn out quicker than they should. Our problems may be totally different, but that's my experience for what it's worth, and if you've found a solution to yours I'm interested.
