A disc brake is a type of wheel brake that works by pushing two backing plates called brake pads against both sides of a metal circular part called break disc, which is connected to the wheel. Mechanical, electromagnetic, hydraulic or pneumatic systems are used to move the pads. The friction that results from the contact between the brake pads and the disc converts kinetic energy into heat, thus allowing reduction of speed of a vehicle.
The brake discs are usually made of grey iron, a type of cast iron. Due to the great resistance of that metal, the brake discs are able to endure big amounts of friction and rarely need to be changed. The brake pads, on the other hand, are softer and wear out more frequently. When the brake fluid level gets low it means that it is time to replace the brake pads.
You have to keep several things in mind when buying new brake pads. Although every car model has its own recommended type of those, you can choose something different that suits your style of driving and the way the car is used best. For instance, you may buy soft compounds, which are more aggressive and are perfect for an extreme style of driving. However, they do not last long, and you will have to replace them soon. That is why most car owners choose harder and more durable pads.
NK offers various types of brake pads which will fit in most European car models. They are made of different materials, according to their type, but it is always a high-quality one. That allows increased durability and rids brake fade (situation when the brakes get too hot, becoming less effective). Safety is a major issue when it comes to breaks, so it is very advisable to choose something reliable, such as the NK production.
