Brake disc heat soak
Estimate brake-disc temperature rise from a single stop. Cast-iron discs fail above ~700°C; race-spec carbon-ceramic above 900°C. Track-day tuners use this to check brake hardware adequacy.
Disc temperature limits
| Material | Safe sustained | Failure |
|---|---|---|
| Cast-iron OEM | ~500°C | 700°C (cracking) |
| Cast-iron drilled / slotted | ~550°C | 700°C |
| Race-spec cast iron | ~650°C | 800°C |
| Carbon-ceramic OEM (Brembo, AP) | ~750°C | 900°C |
| F1 carbon-carbon | ~900°C | 1100°C+ |
