FLUID LEVEL CHECK
See Figures 1 and 2
The brake master cylinder is attached to the brake booster which is located on the firewall (driver's side). To check the fluid level, proceed as follows.
- Clean the area around the cap since even minute particles of dirt can cause a malfunction of the system.
- Remove the top from the reservoir and check to see that the fluid is up to the marks stamped in the reservoir.
- Add fluid, if necessary, to bring the level up to the marks.
Use only a high quality brake fluid. Mercedes-Benz recommends ATE Blue Original brake fluid. In countries where this is difficult to obtain, use only fluid which meets or exceeds SAE J 1703B standards. This will be marked on the container.
- Replace the reservoir cap, making sure that the ventilation bore in the top is not blocked.
