[Vwdiesel] Not Deisel, just brake bleeding hell on a VW bug question

[Tony and Lillie]

Well, the drums on a big rig will expand to the point at which the linings 
won't come in contact, which is the danger of letting speed get too high 
down a continuous grade. However, on a car that's not a problem. But I'm 
still unsure how they tighten, but you may be onto something. Either way, 
I've experienced it, so I know it can happen.
