4) As in F1, the braking systems are the same for all the tracks. FALSE
Unlike Formula 1, where each team uses the same model of brake caliper for the whole season (allowing, of course, for technological evolution during the season itself), in the Nascar Cup Series, the three different types of oval course call for three different types of brake caliper, due to differences in how the brakes are used. On Super Speedways (ovals of 2.5 mi inches and more in length), the brakes are never used except to enter the pit lane or when a yellow flag is shown. On Intermediate tracks (1-2.5 mi tracks) the brakes are used very sparingly, whereas on Short Tracks the braking system is used throughout the entire turn.
As a result, on Super Speedways the calipers are smaller, on Short Tracks they are bigger and on Intermediate tracks they are somewhere in between. Moreover, while in Formula 1 the size of the discs used is the same throughout the year and only the configuration of the ventilation holes changes (with a choice of medium cooling, high cooling and very high cooling configurations with 800, 1,250 and 1,480 holes respectively), in Nascar, the diameter and thickness of the front discs change depending on the type of circuit.
