Brakes are compulsory systems used to slow a vehicle’s speed or used to bring a vehicle to a complete halt. A combination of drilled and grooved disc brakes and a grooved disc brake are designed to reduce the effect of built up heat on the braking component while maintaining the complete structural integrity that the brake disc rotors would experience during heavy braking. Creating grooves and drilling holes reduces the heat capacity of the rotors and may render them weaker and less durable but allows for increased ventilation for effective braking of motor vehicles. The aim of this report is to determine the correct design specifications and parameters to design and model an effective grooved and combination of drilled and grooved brake disc. The amount of holes and grooves increasing the ventilation in a combination disc brake rotor will make it more durable than the grooved disc brake rotor due to increased heat dissipation but may render it weaker. The disc brake system designs were determined allowing conceptual design specifications such as grooving and drilling dimensions, benefits of grooving, drilling and vane systems sizes that allow the rotor to cool itself from the thermal heat without affecting the integrity of the disc.
