Depending on the number of vehicle kilometers need to do maintenance projects are different, automobile maintenance project are many different kinds of oil, thinking the old drivers know when to replace, it brakes when the oil needs to replace it?

Some people feel that brake fluid is in a sealed container, not vulnerable to outside contamination so you can use for a long time, although it is not different from oil brake fluid work environment is so bad, but oil brake oil is also a few kilometers limit.

What usually when to replace oil is to be written on the manufacturer's maintenance manual, 2 years or 40,000 km need to be replaced when the brake fluid, but not too agree to this time most older drivers, in fact, during this period must most of the brake fluid is not a problem, if the 4s shop is recommended that you replace the pretext of fact, this is the name of making money, but as car owners will be judged when their car is the real need to replace the brake fluid .

Despite the number of kilometers and time limits may be determined based on performance of the brake fluid, usually need to be replaced before the precursor will appear, as it is like the front sick different physiological reactions occur, there will be the same when the brake brake oil change needs to be replaced soft, braking distances and so on, then it is necessary to replace the brake fluid.

Brake oil belonging to high concentration liquid having a strong adsorption capacity of moisture in the air, when the temperature of the adsorption of water will affect the performance of the brakes, brake pads when the brakes and brake pads become extremely high, brake wheel cylinder will follow increased, because the water does not have the high temperature and compressibility, there will be water vapor in the face of high temperatures, there will be anomalies during braking, brake failure may even occur.

If you are not a more experienced driver could not find the precursor does not matter, now there are many online brake fluid detection pen can try, or by visual inspection of the normal oil into yellowish transparent color, if the oil becomes dirty or contaminated it shows the need replaced.
