Remove the road wheel and slacken the brake-shoe adjuster.
Remove the two countersunk screws (1) (pressed wheels) or the four nuts (wire
wheels) and withdraw the brake-drum (2).
Inspect the linings (3) for wear, and clean the dust from the backplate assembly
and drum, preferably using methylated spirit (denatured alcohol). Brake lining
dust is dangerous to health if inhaled and therefore should not be blown from
the drums. Make certain that sufficient lining material remains to allow the car
to run until the next regular inspection is due without the thickness falling below
the safe limit.
Refit the brake-drums and road wheel, and adjust the brake-shoes.
