What is a Flex B Service?

Flex B service or 2 wrenches shown on the dashboard will follow the next year or 10,000 miles after Flex A service. It includes the same repairs as Flex A but it also includes an air cabin filter replacement, and a brake system flush. It is required every 2 years per Mercedes-Benz factory recommendations. Brake fluid is hygroscopic meaning it attracts water/moisture. Over time this lowers the boiling point of your brake fluid and can cause total brake failure. This service is highly recommended.
