55 --- Drum brake noise
Drum warped or oval. This can cause intermittent rubbing of the brake linings against the drum. See the preceding Section.
Brake linings glazed. This condition, usually accompanied by heavy lining dust contamination, often induces brake squeal. The surface of the linings may be roughened using glass-paper or a fine file.
Return springs vibrating. See Chapter 9 - Wheels & Brakes.
