When should rear drums be replaced?

Do drum brakes auto adjust?
If they get too far away from the drum (as the shoes wear down, for instance), the piston will require more fluid to travel that distance, and your brake pedal will sink closer to the floor when you apply the brakes. This is why most drum brakes have an automatic adjuster.

What could be the possible reason of oil leakage in one of the rear brake drums in a tractor?

Can a caliper leak brake fluid?
