The fluid needs to have high boiling point to withstand the heat due to the friction when the brake pad touches the brake rotors. If it isn't because of this characteristic, the liquid will evaporate which is the last thing you want to happen as it will result to a soft brake pedal and a compromised braking power.

You may wonder, does brake fluid dissipate over time? Here is the short answer: Yes, brake fluid can go bad. Brake fluid absorbs moisture, which reduces its performance. For that reason, it's best practice to change brake fluid every two years.

Similarly one may ask, can brake fluid dry up? This is a much more serious issue. If a leak is left unrepaired, it can cause the brake fluid to run dry. The worst- case scenario may result, in which the driver presses the brake pedal to the floor but the vehicle does not stop.

Besides above, what causes brake fluid to disappear? While a leak is many times the cause of low brake fluid, there are a few other possible culprits: Leakage into the brake booster. Sometimes brake fluid can leak internally into the brake booster. When this happens, not only will there be no visible signs of a leak, but your brake booster can become damaged as well.

Likewise, can i just add more brake fluid? If your brake fluid level is below the 'low' marker, you should add fluid to top it up. If you check the level soon after and it is still low, you may have a leak in the brake system. This can also be caused by worn brake pads – when worn, brake calipers have further to move this draws more brake fluid into the system.

Does brake fluid need changing every 2 years?
