Why is it recommended that my Brake Fluid is changed every 2 years?



Helping you understand your BMW

Brake fluid absorbs moisture as it is hygroscopic. When this happens it lowers the boiling point which in time can cause a spongy pedal and loss of braking efficiency which will have a negative effect on your braking ability.

The water absorption is greatly increased with the combination of time and mileage.
