Problems solved by technology

Therefore the brake fluid cannot circulate
[0009] 3) Air resistance cannot be completely eliminated automatically
Brake calipers will generate heat when braking, lack of cooling measures and settings, high-intensity frequent braking will cause the temperature of the brake calipers to rise sharply, cause the brake fluid to vaporize, generate a large amount of air resistance, and cause brake weakness or failure , there are serious safety hazards and poor reliability factors
[0010] 4) Pollution booster pump
The brake oil pipe is connected to the middle of the brake caliper. Rust or impurities will be generated inside the brake caliper, which will generally gather in the middle and lower parts. When the brake fluid returns to the booster pump, pollution will occur, and serious pollution will cause brake failure.
[0011] 5) Full-effect braking; the air resistance inside the hydraulic system will be generated from time to time, but the method of manually releasing the air resistance cannot always discharge, and the full-effect braking cannot be guaranteed all the time, and there is a problem of low braking efficiency
[0012] 6) Braking and releasing the brakes are slow
In addition to low efficiency and poor flexibility, it will also cause many secondary problems such as heat generation of brake calipers.
[0013] 7) Lack of protection against impurities; the booster pump and the brake caliper are open and interactive, and are easily polluted by impurities, especially destructive impurities, and lack protection settings
[0014] No reports have been found on the automatic circulation system and the automatic circulation braking system it builds
