It=E2=80=99s an often overlooked issue. I ran into the back of a Lotus =

kinetic energy into heat. It would seem the deeper the reservoir the =
better they would work, and that=E2=80=99s true for the disk, but not =
the pads. It turns out that competition pads=E2=80=94those designed to =
handle higher temperature, don=E2=80=99t start conforming to the disk =
until they get hot enough regardless of how hard you stand on the pedal. =
They also initially off-gas a little, which might also reduce friction. =
Initially Peyote had some kludgy dryer-duct cooling which I think Tony =
