●
Brake fluid is essentially a corrosive, water-soluble fluid for
low-temperature hydraulics and is not an actual oil. Brake fluid
tends to absorb wetness in the air causing the boiling point to
decrease and the brake fluid disc to boil due to prolonged
friction. Brake fluids with lowered boiling points are more likely
to boil and generate vapor due to heat absorption. Since the
brake fluid circuit is a sealed fluid system and no air is allowed
to exist, the boiling steam will affect the transmission of the
fluid pressure channel and finally cause brake failure.
●
Generally, the brake fluid should be changed every 20,000
kilometers or within two years. Detecting the boiling point of
brake fluid is to determine whether the brake fluid is good or
bad, which is closely related to driving safety.
●
In addition to the above-mentioned reasons that will cause the
air lock phenomenon to cause the brake to fail, it will also
greatly consume the additives in the oil, causing the brake fluid
lose its protective ability and acidify the brake fluid. And it will
produce copper ions, which will cause metal corrosion and
produce sludge, and finally, jam the master cylinder and
sub-cylinder of the brake system, and damage the ABS.
