Automotive brake system quality appraisal

The braking system of a car is: a series of specialized devices that can forcibly reduce the speed of the car. The braking system is mainly composed of four parts: energy supply device, control device, transmission device and brake. The main function of the
braking system is to slow down or even stop a moving car, keep the speed of a car traveling downhill stable, and keep a stopped car stationary.
In the case of automobile braking system quality appraisal, Zhongke Testing can provide automobile braking system quality appraisal services.

The automotive braking system consists of:
1, energy supply device, including various components that supply and regulate the energy required for braking and improve the state of the transmission medium;
2, control device, which produces braking actions and various components that control the braking effect;
3, transmission device, including various components that transmit braking energy to the brake, such as brake master cylinders and wheel cylinders;
4, brakes, which produce components that hinder vehicle movement or movement trends.

Liu bought a car. Three months later, while driving, he was rear-ended due to brake failure, and the person involved was seriously injured.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" in the car's braking system involved.
appraisal analysis results:
The appraisal analysis expert group discussed the relevant information and on-site investigation of the car's brake system involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
The brake hose of the car's brake system does not have a fixing device. When the car is running, it is easy to cause the brake hose to rupture. In addition, the victim violated the regulations and overloaded. In this case, the braking capacity was reduced and the accident occurred.
