What should I do before replacing my Drum brake?

If that is the case, be sure to liberally spray the drums with brake cleaner to remove any of the film that may be present before installing them. Step 2: Install the drum brake over the brake shoes.
How do you remove the drum from a car?
Grab the brake drum by the edges and pull it off. It may help to wiggle it a bit as you pull. It may be necessary to back off the brake adjuster to remove the drum. This is done through the brake adjustment hole in the drum or on the backing plate using a brake adjuster tool to turn the adjuster to loosen the brakes enough to remove the drum.

Brake drum condition should be factored in when determining the cause of rear wheel lockup. An out of round brake drum or drums that vary in diameter too much from side to side could cause a one wheel lockup condition (Figure 61.8). Measuring drum runout or out of roundness is not easy in the field.
