Disc Brakes on Early A's - What solution did you choose and why?

That sounds quite reasonable. I've never driven a car with 9 inch drums, but 10 in drums seemed to stop fine to me, especially on an "A" body.

3 words "scary brake fade"! they just dont work well after they are heated ie. going down a grade, or hauling 5 teenagers joyriding (oops, slip). They also dont work well wet, course no drums work well until they are wiped but sometimes you dont have time unless you ride them a little going through puddles.
