Heat spots, hard spots and out-of-round drums — decision guide for workshops serving loaded commercial vehicles.
What you will gain from this guide
- Hard spots cause pedal pulsation after linings bed
- Thin drums exceed discard diameter — replace
- Match lining grade to drum condition
Scored brake drums on loaded CVs reduce stopping confidence and accelerate lining wear. Knowing discard limits avoids unsafe thin drum reuse.
Decision guide
- Measure inside diameter vs discard spec
- Resurface only within manufacturer limits
- Replace drums in axle pairs when possible
Parts ordering
- Order drums and linings as matched sets
- Use genuine linings for passenger duty
- Search brake parts by axle part code
