After entering the winter, many owners have noticed the car maintenance, will be the timely replacement of oil, check antifreeze change etc.. But neglected to safeguard the traffic safety important part -- Brake oil.

One, what is the brake fluid brake fluid brake oil =?

Brake fluid is a liquid medium braking pressure transmission automobile hydraulic brake system, used in adopting hydraulic braking system in vehicle. Brake fluid is called brake oil or force oil, is an indispensable part of the brake braking system, and in the braking system, it is passed as a force of the media, because the liquid can not be compressed, so from the total pump output pressure through the brake fluid is passed directly to the pump.

Two, how to choose the high quality of brake fluid

1 appearance: high quality brake fluid appearance with honey like, pale yellow ordeep yellow, drops in the palm friction will be more and more hot. Inferior brake oilcontaining alcohol taste, liquid like water, and there may be some impurities and suspended matter.

2 boiling point: the boiling point of the higher the better, when the car long time running, the temperature will rise to the number of Baidu. If the boiling point of the brake fluid is not high enough, once the brake fluid brake as the temperature is more and more high, will vaporize, bubbles, causes not immediately brake, as can notguarantee driving safety.

3 freezing point: a point of the brake fluid is the most important fluidity, which is especially important in cold area. The quality of brake fluid in low temperature environment is still a sensitive and reliable. But the inferior brake fluid with high solidification point, when the temperature is decreased to a certain extent occurs solidification phenomenon, greatly reducing the braking performance.

4 corrosion: high quality brake fluid corrosion to metal and rubber is small, can prolong the life of the brake pump. But the brake fluid poor have more corrosive tometal and rubber, will cause the vehicle oil, brake turnover, resulting in serious accidents.

Three, replacement of brake fluid

The use of a certain period of time will be a timely replacement of brake fluid. In general, 1~2 km after check a brake fluid, and when 3~4 million kilometers or 2 yearsmust be a brake fluid replacement. After entering the winter, brake fluid before use itmay not meet the temperature requirements, timely check replacement.

Brake fluid replacement is best to professional 4S shop or special shop. In the replacement of brake fluid, to pay attention to the maintenance staff is first cleaned with alcohol brake system, the brake fluid can not mix different brands, to clean the brake system. When replaced by appearance, to distinguish whether the inferiorbrake fluid.

Brake for vehicles is the most important part of the brake fluid to a crucial role in it. So to timely inspection, timely replacement, in order to place the prevention of accidents.
