With the rapid development of society, the demand for family cars is increasing, which drives people's consumption of cars, and obviously the demand for cars has also steadily increased. The vigorous development of the automobile industry and the continuous emergence of various new automobiles have accelerated the rapid development of the machinery industry, such as high quality brake discs and brake drums of automobile parts. Because many car owners now attach great importance to the maintenance of their vehicles, and some even modify and upgrade their vehicles to achieve faster starting and braking performance, it is necessary to understand the braking effect of the braking system on their vehicles . Since then, this article mainly analyzes how the brake disc works from the the main components of the brake disc, Passenger car brake disc system and  the working principle of the brake disc.

The main components of the brake disc

 

These components are the brake pads, calipers, disc brakes and the hydraulic system.

A disc brake is similar to a bicycle brake. When pressure is applied to the lever, it pulls on the metal wire, squeezing the two brake calipers together and causing friction between the rubber pads and the metal rings on the tires.

 

Similarly, on a car, when pressure is applied to the brake pedal, it forces fluid through the piston and tubing to squeeze the pads together.

 

In automotive disc brakes, the pads squeeze the rotor rather than the wheel, and the force is transmitted hydraulically rather than through a cable. Friction between the pads and the brake discs slows the car down and the discs become very hot.

 

Most modern cars use disc brakes on the front wheels, and some high-performance cars have disc brakes on all four wheels.

 

 

Disc Brake Systems

 

The electric revolution may still be in its infancy, but there's no denying that fossil fuel-based engines are lending a hand. However, whether battery-powered or fuel cell-based engines, the green cars of the future will still need to prioritize passenger safety in any commercial or mass-produced vehicle. It's safe to assume, then, that braking systems will remain unchanged for the foreseeable future, until, of course, more revolutionary systems can be produced.

 

Most vehicles produced today use high quality auto parts; some manufacturers still use drum brakes, but they pale in comparison to disc brakes.

 

Disc braking systems involve many different components, but the most basic function of the system is that it consists of a disc/rotor, a caliper, and brake pads. When the brake pedal is depressed, the brake fluid creates pressure and squeezes the pads and rotor, creating friction. This friction slows the rotation of the wheels and the car itself. Obviously, each component is designed to maximize braking performance.

Working Principle of Brake Disc

 

The brake rotor is an iron disc connected to the wheel hub of the tire and used in the disc brake assembly. Disc brakes are mainly used on the front wheels of vehicles, but are also increasingly used on the rear wheels. The rotor and brake pads work hand in hand to stop the vehicle. When you step on the brake pedal, the brake pads of the vehicle will generate friction on the rotor. This friction stops your vehicle and also generates a huge amount of heat. The rotor consists of two iron discs connected by ribs. When braking, the brake pads will press on the two iron discs. There are many different rib designs for long life brake discs, but they all serve the same purpose. They help dissipate the large amount of heat generated by friction between the rotor and the brake pads. These ribs allow hot air to escape from the rotor, and can also guide air into the rotor to cool the rotor. For rotors, it is very important to be able to dissipate a lot of heat so that they can work properly.

 

Therefore, nowadays disc brakes are more effective and reliable due to advances in materials and improved manufacturing processes. Winhere Auto-Part Manufacturing Company can provides the satisfied brake disc to the customers according to the accumulated designing experience and more experiments.
