As the most important configuration of the body - brake system, is the car when the car is particularly concerned about, its function and performance will be directly related to the vehicle's driving safety.
We often see in the car to buy some low rear wheel with drum brake, while the same type of four wheel brakes will appear in the medium and high with models.This also prompted some consumers to form a drum brake disc brake In fact, from a mechanical principle, the disc brake may not be 'tall', drum brake may not necessarily represent 'inferior'!
Brake brake is the most widely used brake system in passenger cars, and its main structure is composed of brake pads, brake calipers and control system. Its working principle is to rely on the oil pressure to brake the brakes in the brake calipers Disk, to play a deceleration wheel, brake the purpose of the vehicle.
First of all, from the appearance of the brake disc brakes than the brake a lot of exquisite, full of sense of science and technology. In addition the disc brake heat and drainage better, rapid response, uniform braking force, suitable for high frequency braking action. This is also more in line with ABS, ESP Such as vehicle safety requirements of active safety systems, so now the car, SUV and other models are mostly used this brake.
Because the brake is slightly higher than the drum brake cost, so some models with low version, the front wheel disc brake drum wheel brake ratio to reduce costs.
Drum brake, brake disc brake effect is not as good?
In fact, not necessarily, compared with drum brakes braking capacity is better than the disc brake drum brake is the earliest application of the brake system in the vehicle, brake drum with the wheel rotation, rely on brake pads in the brake drum to do 'external support 'Action, friction with the brake drum, to play the purpose of braking vehicles.
Brake brake brake force is larger, more suitable for braking force demanding trucks use.But the disadvantage is obvious, poor heat dissipation, inconvenient maintenance, uneven braking force.
Due to the relatively sealed drum brake system, braking brake pads and brake drum powerful friction, the heat can not be discarded as fast as the disc brake.This also makes some large trucks while traveling to the side of the tire to the water, one In order to reduce the tire temperature, but also can ease the drum brake release of heat.
As a passenger car, four-wheel disc brakes uniform braking, rapid response, in particular, has become the standard ABS, ESP became the mainstream era, no doubt the best choice.However, we can not overlook the traditional image of the drum brake, Its braking force and stability, can not match the disc brake.
