Spinning this off from Chris Zavaston's
comment on brake disc temperatures:
Has anyone tried putting dabs of
Tempilaq
on their brake discs to determine how hot they really get?
I just weighed an old brake disc.
Based on that and a Cp of 500 J/(kg-K) and
mid-weight, 80 deg day
Max braking from speed x will raise the
disc temperature to y degrees
25 kts 220 degF
35 kts 350 degF
45 kts 530 degF
55 kts 750 degF
Keep those brake lines protected.
