Checking the brake fluid level (Mercedes-Benz E-Class W210)

Despite the fact that the system has only one brake fluid reservoir, if there is a leak in one of the circuits, all the fluid does not flow out, since the reservoir has two chambers. If the brake fluid level is insufficient, a warning light comes on in the instrument cluster, but even despite this, visual inspection should not be neglected.

Sequence of works

1. Open the hood and wipe the brake fluid reservoir with a rag.



2. The brake fluid level in the reservoir should be between the "MIN" and "MAX" marks (Fig. 8.6). Do not add fluid if the level is not below the "MIN" mark.

3. Fill the reservoir with only the DOT 4 brake fluid recommended by the manufacturer.



4. A sharp drop in the brake fluid level over a short period of time indicates possible leaks.

5. The leak location must be identified immediately. For greater confidence, have the system checked by a service station.
