35. The temperature increase computed with this equation is the average of all the friction generating components. Some of the heat is absorbed by the brake drums and rotors, some goes into the shoes and pads, and some is conducted into the wheel cylinders, calipers, and brake fluid. NOTE: The possibility of brake fade caused by heat can be reduced if the transmission gear selector is placed in a lower gear when descending a steep or long hill to reduce amount of braking needed to maintain a safe road speed. Engine braking will help keep vehicle speed under control.
