Type and Braking Principle of Brake Pad

Type and braking principle of brake pad

According to the type, it can be divided into disc brake pads and drum brake shoes

Disc brake pads are generally used for small cars and sedans


Drum brake shoes are mostly used by medium and large trucks and buses, and the rear brake of a few cars is drum type

Braking principle of brake pads: the brake pads play a braking role through friction. The friction between the brake pads and the brake discs (or brake drums) is used to convert the kinetic energy of the vehicle into friction thermal energy, so that the vehicle slows down / stops.

Fixed caliper disc brake: characterized by two pistons


Floating caliper disc brake: characterized by only one piston


Drum brake
2、 Formulation and characteristics of brake pads
Where is the friction material of the brake pad?
In December, it was winter, and two identical new cars were delivered at the same time. The first car was transported to Harbin(an extremely cold area in winter in China), where snow and ice were flying. The car was parked outside at - 30 degrees. The car owner hopes that the brake system can operate perfectly, smoothly, without noise and shaking. The second one was sent to Hainan(An area that is extremely hot in summer in China). The car owner decided to take his family on holiday. The car is heavily loaded and runs on country roads. The brake temperature is at least 650 ° C. He also expected good braking effect, smooth, no noise, no shaking, and emergency braking. Of course, both of them hope that the service life of the brake pads will definitely reach 100000 km.
This is a great challenge!
The same friction material must be used in extremely cold and hot conditions.
The driving speed will vary from 5 km / h to 250 km / h
Driving habits: from an old gentleman to a sports driver, the car has different loads.
Yusin brake pads provide you with reliable braking performance in a variety of environments,
Protect you and your family.
