The disc brake pad is a component of the disc brake system. It is fixed with the tires of the vehicle and rotates at the same speed. The disc pad and the caliper cooperate to brake the vehicle. It is divided into disc type, ventilated disc type and friction plate type. So, how do disc brake pads make the car brake?

Disc brake pads with ventilation holes have a set of blades between the two sides of the disc, which can extract air through the disc for cooling. Disc brakes have better heat dissipation than drum brakes, and they are less likely to cause brake degradation and brake failure when the brakes are continuously stepped on. The change in size of the brake disc after heating does not increase the stroke of the brake pedal.

The disc brake pad system responds quickly and can do high-frequency braking actions, so it is more in line with the needs of the ABS system. Disc brake pads do not have the automatic braking effect of drum brakes, so the braking force of the left and right wheels is relatively even. Due to the better drainage of the brake disc, the situation of poor braking caused by water or sediment can be reduced. Compared with drum brakes, disc brakes are simple in structure and easy to maintain.

The mode of action of disc brake pads is similar to the braking mode of our general bicycles-a rubber brake disc connected to the wheel rim interacts during braking until the wheel stops rotating. The important thing is that disc brake pads can be easily matched with the ABS system and used more on medium and good cars; while drum brakes have lower cost, higher absolute braking force, and easier to brake with one foot! It is more used in the rear wheels of ordinary small cars, which is generally called the front disc and rear drum!
