The brake is a major and vital component to slow down and stop a vehicle. If the brake
malfunctions, it can cause a fatal accident or seriously injure either passenger or other road users. That
is one reason why research is conducted to improve the capability and reliability of vehicle braking
systems. The thermo-mechanical properties of the material for better disc brake components have been
investigated. Some geometrics of the disc brake design models have also been studied to determine the
heat distribution that occurs during braking. However, brake failure cases still occur frequently. Most
of the brake failures are preceded by the occurrence of overheating when the vehicle is braked
continuously on a declining road. This indicates that the heat dissipation system during braking does
not work well. This study focuses on designing an unconventional brake system, that uses an active
cooling system. Under conditions of large braking loads, the brake system will actively cool down by
spraying water on the caliper so the brakes will not experience overheating. The design of this system
consists of temperature sensors mounted on the caliper, an over-temperature control unit and also a
cooling unit. The design is implemented on a four-wheel vehicle brake model. The increase of caliper
temperature at the time of braking is simulated by putting the temperature sensor on the Bunsen
burner. The results of this study shows that at various levels of temperature increases the system
works very well
