Brake drum - inspection and renewal

Note: Before starting work, refer to the note at the beginning of Section 2 concerning the dangers of asbestos dust.

1 Whenever a brake drum is removed, brush out dust from it, taking care not to inhale it as it contains asbestos and is injurious to health.

2 Examine the internal friction surface of the drum. If deeply scored, or so worn that the drum has become pocketed to the width of the shoes, then the drums must be renewed.

3 Regrinding is not recommended as the internal diameter will no longer be compatible with the shoe lining contact diameter.
