Brake Fluid is forced into the wheel cylinder, which pushes the brake shoes out
so that the friction of the shoe linings against the drum causes the wheel to stop.
The friction surfaces of the shoes on a drum brake convert the forward motion of
the car or truck into heat. Heat and friction of the shoe linings causes the material
to wear out. This is what gives the dust in the drum when it is removed.
Eventually the shoe linings will wear out and require replacement.

Regular periodic maintenance of removing the drums, cleaning the dust, and
adjusting the shoes will give longer life to the brake shoes and the front brake
pads. Very dusty and misadjusted rear brakes can cause premature wear of the
rear shoes, poor stopping ability, and a heavier load on the front brakes,
causing front pads to wear out quicker as well.
