In addition, over time the moisture can cause internal corrosion in the brake lines, calipers, the master cylinder and other components. Brake fluid is often light brown in color, and in some vehicles it’s clear (at least when new) but will darken with age, becoming murky from water contamination.

Are fluid flushes necessary?

Unless your vehicle’s maintenance schedule specifically calls for a fluid flush, you should never need one. Some manufacturers do require a flush as part of regular maintenance, but it’s not too common. A system suffers a catastrophic failure that contaminates the fluid with debris.

The reasoning behind flushing the old brake fluid is to remove any water content that can lower the boiling point of the fluid, thus reducing the fluids capacity to do its job. Mixing fluids with good intentions might only leave you with more problems, such as failed seals due to using the incorrect type of fluid.

What is the difference between brake flushing and bleeding the brakes?

Note that brake flushing and bleeding the brakes are two different procedures. Brake flushing involves removing all the brake fluid from the system and getting all-new, clean fluid inside.
