Brake Thermal Design
The general brake thermal design is to limit the theoretical temperature increase of brake after a hard
braking below a certain level and derive the proper brake dimensions. Equation (1) describes the
theoretical temperature increase in °C, of a front disc brake.
A typical thermal design goal is to limit the theoretical temperature increase to less than 230°C after a
complete stop from 128 km/h at 0.7 g deceleration and GVW. The use of a brake body material with high
specific heat and a solid disc brake help to meet this goal. Aluminum and its alloys are good candidate
materials for this application.
