When the car is under long-time driving, high speed or downhill, the temperature of brake fluid will get higher with the brake shoe’s temperature. If the boiling point is not high enough, the brake fluid will vaporize with bubbles; the brake will lose control and cannot assure the safety of driving.

The brake fluid in good quality has the better anti-rust feature to every kind of metals and anti-corrosion to every kind of rubbers, which can prolong the pump’s service life. The general or bad quality of brake fluid will corrode the metals or rubber very soon, and result in oil leakage or flip when braking and causing an accident.

Low-temperature fluidity is very important, especially in the cold area. Good brake fluid has sensitive and reliable braking performance in cold weather. Bad brake fluid has poor low-temperature performance while it has a high freezing point. When the temperature reaches -20 degree C, the brake fluid will get frozen and affect the driving safety.

If the brake fluid is unstable, it will occur to thermal decomposition and produce sediments, it will affect the braking performance. Therefore, choosing high-quality brake oil is the must.
