remove vapor
●
The typical working temperature of brake calipers is about
150°C~200°C. If the boiling point of the brake fluid is detected
to be 180°C when the brake fluid is taken out from the mouth of
the reservoir, the brake fluid caliper point is actually only about
155°C, because the rubber tubing easily absorbs water, result-
ing in a large difference.
●
In fact, it is impossible to completely prevent vapor from enter-
ing, so vapor will enter the brake fluid from the brake fluid
reservoir cover, rubber hose, and connector gap.For the major-
ity of cars, vapor increases by about 2% over a year, and this
alone can significantly affect brake fluid quality, so it should be
taken seriously.
The only way to remove water vapor is to use twice the amount
of brake fluid. One bottle is used for rinsing to remove residual
vapor in the pipeline, and the other bottle is used for adding
and refilling the pipeline.
