The best grease is a synthetic brake grease, it is designed to be water
proof and accept all that nasty brake dust and keep on working. I've been
using it for years on drum and disk brake wear surfaces and never had a
problem. however, never put any lubricant on the auto adjusting threads in
drum brakes this always causes the dust to accumulate in the threads and
binds up the adjustment screw (It's ok to clean them any way you like, just
don't leave any residue on the threads).
