Generally speaking, the brake system of a family car is hydraulic, that is to say, after we step on the brake pedal, the power is transmitted through the hydraulic pressure in the pipeline. The fluid used in the hydraulic system is a special brake fluid, which is particularly important for the brake system. It stipulates that it should be replaced every 2 years or 40,000 kilometers!
According to the car mechanic, brake fluid has a different characteristic from other fluids, that is, brake fluid is easily soluble in water! If the brake fluid absorbs too much water and is not replaced, it is easy to generate air resistance inside the hydraulic system, which will have a great impact on the braking performance. If our car owner finds that the brakes are not sensitive, we need to ask the master to check and repair the brake system in time.
Under normal circumstances, the exhaust can be exhausted by loosening the brake cylinder, but this cylinder cannot. Where is the problem?
The cylinder exhaust screw causes the brake cylinder to be replaced! Because this screw cannot be bought, it is sold together with the brake cylinder! Its middle is hollow. After the screw is loosened, the cone is separated from the oil pipe in the sub-pump, and the brake oil or gas that comes out is connected to the outside world through a small hole on the side of the cone! The current situation is that there is a problem with this special screw, and it can only be replaced!
The main reason for the blockage of the brake cylinder screw is that there is no rubber cap on the outside of the exhaust hole. The car owner usually drives in a harsh environment, too much impurities enter the exhaust hole, and the rust is still serious. Only replace the cylinder assembly! The air resistance generated by the brake system is mainly because the car owner has not changed the brake oil, which leads to the deterioration of the brake oil and the excessive water content in the oil.
