Your brake fluid requires regular service because it becomes contaminated bymoisture.
How does moisture get into your brake fluid? Brake fluid is hydroscopic, which means that it
magnetically attracts and absorbs moisture from the atmosphere, usually through the brake master
cylinder reservoir and permeable brake hoses.
Moisture contamination lowers the boiling point of your brake fluid, so, even under ordinary driving
conditions, it could cause the fluid to boil and turn into vapor in your brake system. Remember you
can compress a vapor, you can't compress a liquid. As a result you can have a low or sponge brake pedal
increasing your distance to stop.
Moisture contamination can also result in very costly repairs - into the thousands if you have ABS-type
brakes! When moisture-contaminated brake fluid reaches very high temperatures - as much as 450 to 500
degrees - an electrochemical reaction makes the fluid highly acidic. The acid breaks down the steel lines
and rubber hoses and can cause early failure of the cast iron and aluminum components that make up your
brake system.
Brake fluid contamination has become much of a concern; some car manufacturers have added brake fluid service
to their required maintenance schedules. So don’t delay having one of our ASE Certified Technicians perform
this important safety service for you today.
