Why do manufacturers recommend flushing brake fluid every 2 years?

Brake fluid is hygroscopic (bluntly, it means it absorbs water). As the fluid absorbs moisture in the air we breath, mainly through rubber brake hoses and seals, it lowers the boiling point of the fluid.

To put it simply, using the brakes creates tremendous heat and if the brake fluid happens to boil your pedal will more than likely drop to the floor. Every service we send an electronic pulse through the fluid to test it, advising you if it is time to have the brake fluid flushed and changed.
