Now the season is over I have a technical question, a really stupid technical question. We’ve long witnessed the carbon brakes on these cars glow red hot under hard braking with I guess the pads and discs reaching equally high temps.
Hypothetically, if it were possible to jack up an F1 car at the end of a very long straight after maximum braking effort and retardation but with pedal pressure no longer applied could you rotate the wheel, or would the high temperatures without pressure alone offer drag?
Does the disc and pad assembly dissipate heat so quickly so as to be offering no drag the second the brake pressure is removed or do the two surfaces offer drag without pressure until they cool below a certain temp?
Is the composition of the pad and disc different to prevent this, also does all the pad material heat to the point that it transfers heat into the pad backing plate, then calliper and potentially the brake fluid? I’ve certainly never heard of these cars boiling their brake fluid (but overheating their brakes yes!).
I can remember video clips from back in the day where the cabon brake assemblies were “bench tested” and they went through many many cycles showing their ability to dissipate energy through heat, it was quite the sight but don’t remember them showing the disc coming to a stop!
