Fig 4 Eleven Inch Drum Maximum Diameter Identification
NOTE: All drums will show markings of maximum allowable diameter.
For example: An eleven inch drum will have a marking of MAX. DIA. 11.090 inch.
This marking includes 0.030 inch for allowable drum wear beyond the recommended 0.060 inch of drum refacing.
NOTE: Any brake drum sufficiently out of round to cause vehicle vibration or noise while braking, or showing taper should also be machined,
If the braking surface diameter is within specifications: Drums should be cleaned and inspected for cracks, scores, deep grooves, taper, out of
If drums are cracked or heat spotted, they must be replaced.
Minor scores should be removed with sandpaper.
Grooves and large scores can only be removed by machining with special equipment, as long as the braking surface is within specifications
MEASURING DRUM RUNOUT AND DIAMETER
NOTE: Measure the drum runout and diameter with an accurate gauge.
If the drum runout or diameter variation exceed these values the drum should be refaced.
Maximum Single Cut
Deeper cuts are permissible for the sole purpose of removing deep score marks.
CAUTION: Do not reface more than 1.52mm (0.60 in.) over the standard drum diameter.
