The Natural Philosopher gurgled happily, sounding
much like they were saying:

Hmmm -- I wonder what would happen if car manufacturers decided to size
their brakes such that they could easily dissipate the heat from say a
100mph to 50mph panic stop. Those same brakes could then also easily
dissipate the required amount of heat from 50mph to 0mph and thus the
vehicle would only take twice the time to stop from the higher speed
rather than four times. In this "new, enlightened manufacturer"
scenario, the limit for typical panic stop would then not be heat
dissipation at the brakes, but rather tire/pavement coefficient of
friction.

Someone should build a car with brakes like this. Oh, wait -- EVERYONE
DOES!!!!!!!!!!!!

Er. no.

Most production saloons will be starting to fade on just a single
application of the brakes from top speed.

Your jaguars, porsches, and to an extent beemers and mercs will do a bit
better, as will some of the better hot hatches.

But brakes that will do continuous full power almost indefinitely are
only found on the very best sports cars. Or on the race track.

If you've got brakes that are fading from a single 100mph stop, you
desperately need to get them fixed properly - because they most certainly
should not be doing so, no matter what you're driving.

Unless, of course, you've bought the cheapest ****test pattern disks and/
or pads, in which case it's probably to be expected but don't blame the
car's manufacturer.
