Remove brake fluid warning light on Mercedes

Brake fluid warning light on Mercedes continuously flashing on the dashboard while driving is a very dangerous thing. Problems related to important parts such as vehicle brakes need to be fixed immediately. In this article, experts from Eurocartool will show you what to do when the brake warning light on your Mercedes comes on.

What is the meaning of the brake fluid warning light on Mercedes?

The vehicle brake fluid warning light is a part that operates with the purpose of measuring and reporting the fluid level in the car’s brake system. The purpose of this system is to keep the amount of oil at a minimum level, to help the system operate smoothly and to warn of any problems occurring within the brake system.


When does the oil warning light appear?

This warning light may appear after you fully release the parking brake or may appear while you are driving, which may indicate a low brake fluid level.

The second case is that the warning light appears when you are driving in traffic. The phenomenon of a continuously lit warning light signals that the hydraulic pressure system inside the brake system has been lost. Or the fluid level in the master cylinder is dangerously low (due to a leak in a part of the brake system).

Is it safe to drive with the brake fluid warning light on Mercedes?

Do not drive with the brake fluid warning light on the screen. The brake system plays the role of reducing the vehicle’s speed to the required value or keeping the car in place when parked. If the brake system has a problem, it will threaten the driver’s safety during traffic.
In this situation, stop the vehicle on the side of the road when it is safe to do so and check the brake fluid level according to our instructions. Or if you are near a repair garage, keep a low speed, move the car to avoid sudden braking so that the repairmen can check it for you.


3 ways to check and fix warning light problems on Mercedes cars

Checking the brake system after the brake fluid warning light on Mercedes appears on the control screen should be done as soon as possible. If this situation continues, the brake system will be more seriously damaged. There are 3 common ways to check and fix the problem, including:

Check brake fluid

Brake fluid is a pressurized fluid in a hose or brake line to activate the brake pads and brake rotor parts to slow the vehicle down.
Steps to check brake fluid include:

Step 1: Locate the master cylinder, also known as the brake fluid reservoir, it can be found on the driver’s side.

Step 2: Check the fluid level. The tank will have minimum and maximum lines on the side, indicating the ideal range for the liquid level.

Step 3: If the fluid level is too low, new brake fluid must be added to the reservoir. However, before doing so you need to drain the brake fluid.

Additionally, it is important to check the brake pedal. Press firmly on the pedal and observe its reaction. If the pedal sinks to the floor, there may be a leak or air in the brake system. On the contrary, if the pedal feels firm, it is working well.

Check the ABS anti-lock braking system

ABS locking braking system is equipped on most vehicles on the market today. Under normal operating conditions, the brake light only lights up when starting the vehicle and turns off immediately afterward to notify that the system is operating normally. If this system has a problem, it is obvious that the warning light will continuously light up.
In case the ABS brake fails, the system will record the error and save it with a code read by the ABS brake sensor and diagnostic machine. You can find out the exact cause by using specialized diagnostic software and equipment.


Change brake fluid regularly

Brake fluid will absorb water/moisture after a long period of use. If there is water in the brake fluid, it can corrode all kinds of metal parts in the brake system. At this time, you will feel the brake pedal is sluggish and the braking performance is poorer.
Therefore, you should regularly flush brake fluid according to the instructions of experts. Brake fluid change frequency is approximately every 60,000 miles, or depending on how you use your vehicle.

If, after checking and resetting the vehicle, the warning does not disappear, you will need the intervention of professional diagnostic software. Maybe your car is having a sensor or brake system error. You need to use Xentry to diagnose errors your vehicle is experiencing, then identify errors and delete them.

Leaking brake fluid or dirty brake fluid can cause problems in any brake system. Therefore, when the brake fluid warning light on Mercedes lights up, the driver needs to check the brake parts, especially the brake pads and the fluid level in the system.
