6 Pots Brake Caliper CP8520 Black Color Fit 410*36mm Big Disc Kit

Disc brake construction
The brake rotor (disc) which rotates with the wheel, is clamped by brake pads (friction material) fitted to the caliper from both sides with pressure from the piston(s) (pressure mechanism) and decelerates the disc rotation, thereby slowing down and stopping the vehicle.

How disc brakes work
When the driver steps on the brake pedal, the power is amplified by the brake booster (servo system) and changed into a hydraulic pressure (oil-pressure) by the master cylinder. The pressure reaches the brakes on the wheels via tubing filled with brake oil (brake fluid). The delivered pressure pushes the pistons on the brakes of the four wheels. The pistons in turn press the brake pads, which are friction material, against the brake rotors which rotate with the wheels. The pads clamp on the rotors from both sides and decelerate the wheels, thereby slowing down and stopping the vehicle.

The pad is a steel backed plate, with a friction-based material bound to their surface. Usually there will be two housed within the brake caliper, attached to the pistons with the friction surface directed at the disc.

Sufficient friction material on the pad is essential, as the disc may become damaged and worn down without the correct contact during the braking process. Brake pads can come in a variety of different materials, dependant on the type of vehicle needed to be stopped.

In order to stop a vehicle weighing in excess of 1000kg, the pads need to be able to withstand extreme heat and friction. Surprisingly there is a large variety of different materials used for brake pads, all considerably resistant. The most popular material and likely to be on your own car, is a metallic brake pad. They’re a blend of different metals; commonly made of iron, copper, steel and graphite.

Metallic brake pads are heavy though and if speed is the name of the game, then a more lightweight material is needed, such as ceramic
