The principle of the brake system: The principle of the brake system is to create a huge friction, transforming the kinetic energy of the vehicle into heat. As we all know, energy will not be produced out of thin air, nor will it disappear from the air. It can only be transformed from one form to another, or from one object to another. In the process of transformation or transfer, the total amount of energy is not change. In the process of acceleration, the car converts chemical energy into heat and kinetic energy. When braking, the brake system converts the kinetic energy of the car into heat and dissipates it into the air. Repeatedly, the brake system of the car will be damaged, and it needs to attract people's attention and carry out regular maintenance and maintenance on the car.
Replacement of brake pads: 1. The brake pads should not be used to calculate the replacement cycle based on the number of kilometers. It is necessary to determine whether it needs to be replaced according to the actual wear conditions. Because everyone's driving habits are different, the frequency of use of the brakes and the degree of wear of the brake pads are definitely different. If the dogma is replaced according to the number of kilometers, the driver who encounters the brakes is likely to be replaced. At the time of the mileage, the brake pad base will scrap the brake disc. Do more visual inspection yourself, or every time you perform maintenance, please check with the repair technician. If you find that the thickness of the friction material of the brake pad is close to 5 mm, it should be replaced in time, because the brake pedal will become longer as the brake pad becomes thinner. , affecting the brake reaction time. It is necessary to use regular products to replace the brake pads. This involves driving safety, and it is not a trivial matter for yourself.
Brake disc replacement: Compared to the brake pads, the brake disc material has a higher hardness, so the frequency of replacement under normal use conditions is not so high. However, it is also necessary to carry out visual inspections on a regular basis to observe whether the brake discs are abnormally worn or excessively rusted. For example, the surface of the brake disc is rusted with a large area of the groove and can be defined as excessive rust. A small amount of rust can pass through the brake pad. The friction is removed by itself, and the groove cannot be removed quickly. It also causes serious damage to the brake pad, the brake is out of order, and it is found that the brake disc is excessively corroded and the vehicle should be repaired immediately. If the brake disc is deformed, it will cause the vehicle to shake during the braking process, or the vehicle in the vehicle will vibrate. If such an abnormal phenomenon is found, the vehicle should be immediately sent for inspection and repaired.
Brake oil selection: The composition of the brake oil determines that the brake oil must be replaced regularly, because the brake oil is very water-soluble, and it will inhale the air in the air for a long time, resulting in a lower boiling point. Generally, the brake oil is replaced every two years. If it is a wet area, it is necessary to increase the frequency of replacement according to the situation. When replacing, pay attention to the brake oil label used by the vehicle. Different labels of brake oil cannot be mixed. There are three types of brake fluids. Choose a reliable manufacturer when purchasing, and the higher the level, the better.
The brake system should pay special attention to two points in daily use: first, the temperature of the brake system, do not use the brakes continuously, which will cause the temperature of the brake disc and the sheet to rise sharply, which may cause the brake pad to burn or brake oil. Boiling, this will cause a brake failure failure.
The correct way is to reduce the speed of the vehicle in advance during the steep downhill process. Using the appropriate gear and using the engine brake to match the operation mode of the brake system can effectively reduce the burden of the brake system and avoid overheating of the brake system.
