Front disk brakes are ideal for the front of the car. When you're moving forward and you hit the brakes, the center of gravity of the vehicle effectively shifts forward, putting more weight and more momentum on the front tires. The front tires therefore gain more traction, and they can take more braking force to stop the car. Because the front brakes generate up to 75% of the vehicle's stopping force, they generate much more heat, over 500 degrees F in heavy braking. Taking a look at the front disk brakes, especially the size and weight of the brake rotors, brake calipers, and the surface area of the brake pads, it's obvious that the front brakes are a lot heavier than the rear brakes, enabling them to take the heat. Here are some features of front disk brakes: 1) high hydraulic pressure split by the master cylinder delivers more clamping force. 2) larger and multi-piston brake calipers develop more clamping force. 3)larger brake pad surface area increases friction. 4) larger diameter brake rotors for more stopping torque. 5)thicker brake rotors maintain their shape at high temperature. 6) ventilated brake rotors dissipate heat faster.
