The two front wheel brake discs differ form the back by having only one set of pistons, the rear calipers have two independent sets of pistons. The rear pistons were of different sizes in the early cars, while on the latest models they were the same.

The pistons are protected within the piston chamber from dirt by a dust seal. When the brakes are put on action, Hydraulic pressure within the system will increase pushing the pistons towards the disc. The braking pads present between the brake disc and pistons gets forced against the disc surface. This friction cause by the contact of the brake pads and disc causes the car to slow down.

In order to prevent overheating of the pistons they are made of cast iron and the surface is covered with chrome. The fluid moves freely within the caliper through channels drilled in the caliper house from the brake distribution valves, which are connected to the brake pedal. Operating the brake pedal opens the valves which activates the pistons but in order to get some feedback on this action a master cylinder is present, is mounted together with the distribution valves in the brake actuation box right underneath the driver’s seat. Later models got rid of the master cylinder and use a rubber stopper in the brake pedal to get feedback.
