RE: Drum brakes locking up...

    I have had drums act that way when the wheel cylinders are leaking
(slightly, in my case). I suppose one could theorize that a tiny bit of
trapped air in the cylinder created by the small leak rapidly heats and
expands under braking pressure, causing the drum to lock. Then, after a
stop or two, you've forced the air out of the same path as the leak, and the
problem goes away.

Flame-meisters note that the above is a theory, and not mine at that... :)
