Brake Fluid

During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of
moisture from the atmosphere. Under
extremely hard operating conditions,
this moisture content can lead to the
formation of bubbles in the system,
thus reducing the system 's efficiency.
The brake fluid must therefore be
replaced annually, preferably in the
spring.
It is recommended to use only brake
fluid approved by MERCEDES-BENZ.
Your authorized MERCEDES-BENZ
dealer will provide you with additional
information.
