Why is Brake Fluid Important?
Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the brake calipers, causing the brake pads to clamp onto the rotor and slow or stop the vehicle. The brake fluid level should be checked regularly to ensure that it is at the recommended level. Low brake fluid levels can cause the brake pads to wear down faster, leading to premature wear and tear on the brake system. In addition, low brake fluid levels can also cause the brake system to become spongy, making it difficult to stop the vehicle in an emergency.
The brake fluid level should be checked when the brake pedal is in its normal position. The brake fluid reservoir is usually located under the hood, and the level can be checked by looking at the reservoir through the clear plastic window. If the level is low, it is essential to add brake fluid to the reservoir. It is recommended to use the same type of brake fluid recommended by the manufacturer, as using the wrong type of brake fluid can damage the brake system.
Tools and Materials Needed
To add brake fluid to your 2003 Mercedes-Benz E500 W211, you will need the following tools and materials:
- Brake fluid (DOT 4 or DOT 5.1)
- Brake fluid reservoir cap
- Brake fluid level gauge (optional)
- Tire iron or lug wrench
- Socket wrench or ratchet and socket
- Brake fluid container (for disposing of old brake fluid)
It is essential to use the correct type of brake fluid recommended by the manufacturer. DOT 4 and DOT 5.1 are the most common types of brake fluid used in modern vehicles. DOT 4 is a non-silicone-based brake fluid, while DOT 5.1 is a silicone-based brake fluid. Using the wrong type of brake fluid can damage the brake system.
Step-by-Step Instructions
Step 1: Locate the Brake Fluid Reservoir
The brake fluid reservoir is usually located under the hood, on the driver’s side. It is a clear plastic container with a cap on top. The reservoir is connected to the brake master cylinder, which is responsible for transmitting pressure from the brake pedal to the brake calipers.

To locate the brake fluid reservoir, follow these steps:
- Open the hood of your vehicle and locate the brake fluid reservoir.
- Look for the clear plastic container with a cap on top.
- Check the reservoir for any signs of leakage or damage.
Step 2: Check the Brake Fluid Level
To check the brake fluid level, follow these steps:
- Look through the clear plastic window on the reservoir to check the brake fluid level.
- Check the level against the minimum and maximum marks on the reservoir.
- If the level is low, add brake fluid to the reservoir.
Step 3: Add Brake Fluid to the Reservoir
To add brake fluid to the reservoir, follow these steps:
- Remove the cap from the reservoir.
- Pour the recommended type and amount of brake fluid into the reservoir.
- Replace the cap on the reservoir.
Step 4: Check the Brake Fluid Level Again
To check the brake fluid level again, follow these steps:
- Look through the clear plastic window on the reservoir to check the brake fluid level.
- Check the level against the minimum and maximum marks on the reservoir.
- If the level is still low, add more brake fluid to the reservoir.
Step 5: Dispose of Old Brake Fluid
When adding new brake fluid to the reservoir, it is essential to dispose of the old brake fluid properly. Follow these steps:
- Transfer the old brake fluid to a brake fluid container.
- Check the container for any signs of leakage or damage.
- Dispose of the old brake fluid at a recycling center or an auto parts store that accepts used brake fluid.
