Synthetic brake fluid - SWAG DOT4 PLUS (MERCEDES) 1L.

Brake fluid is recommended to be flushed or changed every 1-2 years. Many car manufacturers also require periodic fluid changes to ensure reliability and safety.

This is because moisture is absorbed into the fluid over time, and once the water contact becomes too high, it will affect the performance of the fluid, and thus the brakes. There are also ingredients present in brake fluid that prevent corrosion, which can degrade over time and become far less effective.

Brake fluid is not considered a "top up" fluid, so If it is low, there is usually a problem. The fluid level will drop as the brake pads wear and the calipers or wheel cylinders extend further to compensate. Brake fluid level may also be low because of a leak, which could result in a loss of pressure, and thus a loss of braking ability. It is always best to get the problem checked by a professional.
