Brake drum - inspection, renovation or renewal

1 Whenever the rear brake linings are being checked for wear, take the opportunity to inspect the internal surfaces of the brake drums. 2 If the drums are grooved or deeply scored, they may be reground, provided that their new internal diameter will not then exceed the specified dimension. If it will, or the drum is cracked, it must be renewed.

3 Removal and refitting of a brake drum is described in Section 4.
