But why does water in the brake fluid limit the braking effect so much The new water entering the brake fluid has a lower boiling point compared to the existing fluid, which reduces the boiling point of the entire brake fluid as the mixing ratio increases. If the boiling point of the brake fluid is now reached during braking, vapour bubbles form in the brake system which are caused by the boiling of the brake fluid. As a result, hydraulic pressure is no longer generated on the brakes and the pedal fails during braking without producing a braking effect.

For brakes to function properly, regular brake fluid changes are very important for the safety of a motor vehicle. This maintenance work must be carried out with special care and cleanliness, as even the smallest impurities, such as dirt or small parts, can get into the brake system and damage the brake pistons, for example. So-called brake fluid testers are suitable for determining whether it is necessary to change the brake fluid in a vehicle. These provide reliable information as to whether the brake fluid in a vehicle is still ok or whether it needs to be changed. Depending on the model, the brake fluid tester determines the current boiling point of the brake fluid in the vehicle or the water content of the fluid.

خط ترمز به دماهای بالا حساس است.، بنابراین مقدار مشخصی تبخیر و تراکم در داخل خط رخ می دهد. با تداوم این امر، محتوای آب در خطوط با شروع رقیق شدن روغن ترمز افزایش می یابد. TASI Universal LED Car Brake Fluid Tester یک تستر جیبی با کاربری آسان است. که برای تشخیص آلودگی آب در خطوط ترمز خودرو است.فاده می شود. تستر برای DOT ، و . مناسب است..

As the water content in the brake fluid of a motor vehicle increases over time, the boiling point of the brake fluid decreases more and more. This happens because the brake fluid has the property to absorb water from the air. Vehicles that have been stationary for a long time are also subject to this phenomenon, which is why regular checks are also necessary here. A change of the brake fluid may therefore be necessary even for vehicles with a long service life.
