I've got an '84 toyota 4x4 pickup that when i'm reversing, the brake rubs.
For example, if i'm on a hill and put it in reverse for a second to start
rolling, then put it in neutral, the truck will be rolling backwords down
the hill and come to a stop as if i hit the brakes.  It doesn't seem to do
this when going forward, but i do feel like my not so good gas mileage has
gotten lots worse.

I pulled the rear drums off last night (i replaced the rear pads and drums
about 20k miles ago, figure i messed something up) and didn't see anything
obviously wrong.  The only thing i did see was that on the right side (the
side that was metal to metal when i changed 'em last time), the brake pads
aren't resting exactly snug to the top post of the brake assembly.  I have
also noticed lately that pumping my brakes once when stopping increases my
brake power.

Any ideas?

thanks
