What are the brake system components

Pacific Auto's braking system components are brake pedal, brake master pump, brake sub-pump, vacuum booster pump, brake hose, brake disc, handbrake brake, ABS system, as well as the vacuum booster pump connected to the brake pedal.

In conventional fuel vehicles, the braking system consists of the following parts: brake pedal, brake master pump, brake sub-pump, vacuum booster pump, brake hose, brake disc, handbrake brake, ABS system, and vacuum booster pump connected to the brake pedal. When the engine is working, the intake manifold generates a certain vacuum, and a certain pressure difference with the external atmospheric pressure, which generates the braking assistance. And when the engine is not working, there is no vacuum, but there is a small amount of vacuum in the vacuum booster pump, so that explains why the brake pedal doesn't go down after two presses when the vehicle is turned off, it gets hard.

There is no engine on a pure electric vehicle, so there is no source of vacuum generated by the engine. As a result, the vacuum booster pump does not work and cannot provide vacuum power to the vehicle's main brake pump. The electronic vacuum pump solves this problem by replacing the engine as the power source for the vacuum. However, the electronic vacuum pump can provide limited vacuum, is noisy, and occupies a large space, so it is more in use as a transitional solution. Currently, most pure electric vehicles use electronic braking systems, such as Bosch's iBooster.

This electronically controlled braking system has a high level of electronic integration, using an electric motor and various sensors instead of the traditional vacuum pump design. In the absence of a vacuum source, the torque generated by the geared motor is converted to fluid pressure for braking, which can be interpreted as acting as the main brake pump in a conventional braking system. For pure electric vehicles, this type of electric braking system offers even greater advantages by maximizing the recovery of braking energy through decoupling and increasing the vehicle's range.

An automotive braking system is also known as an automotive braking system. The role of the braking system is to make the moving car in accordance with the driver's requirements to force the deceleration or even stop, in the process of driving play a very safe role. The braking system culminates in brake pads (disc) or brake shoes (drum) to complete the braking action. Brake pump belongs to the automotive braking system, the function of the brake pump is mainly to provide braking assistance, only after the start of the vehicle's engine, with the role of braking assistance, such as passenger cars, trucks and other vehicles with a pump power system, automotive oil pump power system, the main oil of the brake pump is a vacuum booster pump, in the conditions of the total pump power, when the driver to control the oil pressure of the sub-pump act on the braking pressure, step on the brake pedal will be easier to force much easier. If the engine of a burning car does not start, the driver cannot push the brake pedal to the floor even if he uses it to the best of his ability.
