Braking is the conversion of kinetic energy (motion) into heat (and stopping power) by way of friction generated between the brake pads and the brake rotor surface. Put simply, the greater the friction produced, the greater the stopping power. However, with more friction comes more heat. A big brake kit increases the heat capacity of a braking system by incorporating larger rotors, larger pads and larger calipers. The increased surface area lends to greater heat capacity and an increased friction surface. Larger rotors offer more material to absorb and dissipate heat, as well as provide a larger friction area for a larger brake pad to be employed.
Increasing the heat capacity and applying more friction are just two of the benefits that a big brake kit offers. Another important benefit comes in the form of increased torque. The application of torque is a matter of leverage. In the same way that increasing the amount of leverage by way of a breaker bar (torque arm) helps to increase the torque applied (moment of torque) to a bolt or nut, the same principle applies when increasing the rotor diameter and caliper size.
