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.
Don't remember having any brake fade, of course the last time I had drum brakes they were riveted and the linings contained asbestos. I always ran the best linings I could get my hands on.
