Track Wisdom

"Fluid fade... happens when the temperature of the caliper cylinder (or the piston) reaches the boiling point of the brake fluid and tiny bubbles of compressible gas form in and are diffused through the previously incompressible brake fluid. The pedal then goes to the floor, giving rise to frantic pumping of both the brake pedal and the driver's heart[...] Basically, if the pedal goes all soft and horrible you [...] have boiled the brake fluid. The only cure is to either upgrade the fluid or keep it cooler. This can be achieved either by increasing the cooling to the caliper or by insulating the caliper pistons."

-- Carroll Smith, Engineer to Win

Where does the shielded brake heat go?

Not all of the heat shielded by our heat shields is reflected straight back into the pads, some of it is dispersed radially, away from the caliper/pad contact zone. Heat travels from hot to cold areas, so since the pad is the source of the heat most of the time, very little heat will transfer from the cooler shield into the hotter pad. That said, some folks do tend to run higher temp brake pads with our shields, but that is a normal decision that racers are making all the time, matching pad compounds to track and racing conditions.
