Generally speaking, the brake cylinders of family cars are 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 is required to 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 gas resistance inside the hydraulic system, which will have a great impact on the braking function. If our car owner finds that the brakes are insensitive, 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 wheel cylinder exhaust screw causes the brake wheel cylinder to be replaced! Because this screw cannot be bought, it is sold together with the brake cylinder! Its center 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 only replacement can be done!
The main reason for the blockage of the brake cylinder screw is that the rubber cap on the outside of the exhaust hole is missing. 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 of the brake system is mainly because the car owner has not replaced the brake oil, which causes the brake oil to deteriorate and the water content in the oil is too large.
