Now, Aston Martin is a British luxury car makers and being a sports car Aston Martin lays much importance on its brake discs. According to Nice(2014) “Most modern cars have disc brakes on the front wheels, and some have disc brakes on all four wheels. This is the part of the brake system that does the actual work of stopping the car”. The brake disc controls the car in a unique way as it is directly related to the performance of the car. As we know, the brake disc are used for vehicle braking and is usually made of cast iron.

In a sports car like Aston Martin, the break disc is controlled by the amount of pressure placed by the sports driver on the breaking pads. The brake disc is connected with other assembly parts of car like the piston, brake hose, wheel stud, caliper and break hose. The brake disc is exposed to many situation while it is operating and one of them is the stresses. One of the stress is the thermal stress because the car is fast paced and any kind of heat exposure can have credible effect on the brake disc.

In this case study, the brake disc is designed for the Aston Martin and being a luxury sports car, it demands brake disc which can resist much temperature hike. Usually, the break disc need to resist temperature as high as 150 – 300 degree centigrade. When the vehicle operates it is exposed to many situations and the brake disc need to control the wear and tear and also the friction at this point. According to Agnihotri ( 2014,pg.40-49) “The disc brake is a device for slowing or stopping the rotation of a wheel.

Friction causes the disc and attached wheel to slow or stop. Brakes convert friction to heat, but if the brakes get too hot, they will cease to work because they cannot dissipate enough heat”. Normally, the brake disc operates in a harsh environment and should be designed to withstand extreme temperature and tedious service atmospheres. To obtain optimum racing brake and service condition the brake disc is manufactured
