When Should I Change My Brake Fluid?
Brake fluid is hygroscopic, it has the ability to attract water molecules from its surrounding environment or through absorption, also whenever you remove the brake reservoir cap you also expose the system even more especially for long periods. Most modern cars have transparent brake reservoirs, with a (Min-Max) Line so in most cases it is not necessary to remove the cap unless you can physically see it at the minimum line.
Many experts differ as to when to service the brake fluid, we belive as a preventative maintenance the brake fluid should be replaced every two years. Moisture/contamination also contributes to internal corrosion in the ABS Unit, calipers, wheel cylinders, and brake master cylinder. The reason for replacing brake fluid periodically is to get rid of contaminated fluid and restore fluid heat and corrosion resistance.
Most cars with ABS systems would recommend Dot 4 Brake Fluid
