Why does the car need to change the brake oil？

Talk about some of my own views. The brake problem is a part that every car owner cares about very much, because it is related to the safety of driving. When enjoying a convenient and fast lifestyle, safety is the first and must be guaranteed. Therefore, more checks should be made on the braking system in daily driving to ensure the safety of drivers.

After the brake oil is used for a long time, the leather bowl and piston in the brake pump will be worn, resulting in the brake oil turbidity, so it needs to be replaced to ensure the normal use of the brake system. Brake oil is very important for the brake system, when choosing brake oil, you should choose the same size as the original car, the big brand, quality assurance Boston (BSD) brake oil. If it is unqualified, the quality of the general brake oil, will rot the brake pump plug, the effect of the brake will also have an impact.

There was once an experiment on brake oil, in which a cup of water was poured into the brake oil. In an instant, the brake oil and water were easily integrated, and the color changed from clear light yellow to cloudy milky white. After being put for a whole day, the mixture of oil and water did not stratify. Brake oil has the characteristics of water absorption, if not replaced for a long time will corrode the brake system, bring hidden trouble to driving. At the same time, due to the brake oil suction, the boiling point will be reduced, easy to cause the brake pressure shortage, affecting the braking effect.

Water in the brake oil can affect the performance of the brake. The boiling point of water is 100 ℃, if the brake oil contains water, it will reduce the brake oil boiling point temperature. When braking system for brake pads and brake disc friction heat makes temperature reaches the boiling point temperature, the moisture inside the brake oil will boil, and generate bubbles, gas is compressible, there is a certain amount of air bubbles in the brake pipe, on the brake pedal will feel very soft, braking force, serious situation is likely to lose braking force. It's time to consider changing the brake oil (after eliminating problems with tires and brake pads) if the following three conditions occur during driving

1. When the car is normally running above 40KM/h, slam on the brakes, and the braking distance becomes significantly longer. In the exclusion of brake pads, it is almost certain that there is a problem with brake oil.

2. When the car brakes, the brake force is suddenly light and heavy. When the brake oil deteriorates and the water content exceeds 2.5%, the frequent braking generates high temperature, which makes the water in the brake oil turn into steam and a large number of bubbles appear in the brake oil, resulting in unstable brake force.

3, the brake pedal will be soft, brake oil deterioration will make the brake pedal even if the bottom will also give a soft feeling. Especially after continuous and frequent braking, the brake pedal feels much softer and more elastic than before.

Mua, motorists this oil is very important to safety, for safety use, recommended 2 years or 60,000km replacement.
