“Check Brake Pad Wear” | What it means & how to fix it in your Mercedes-Benz
What is causing the “check brake pad wear” message to appear on the dashboard of your Mercedes-Benz? This warning message will pop up when your brake pads have worn down and need to be replaced as soon as possible!
Over time, brake pads naturally wear out, reducing their effectiveness. To fix this issue and make the warning light disappear, you need to change your brake pads. Are you more of a visual learner? Follow along with our video guide above! This guide walks you through replacing your brake pads and restoring proper braking system function. With the right tools and a little know-how, you can change your brake pads and clear that warning message at home.
What does the Check Brake Pad Wear warning mean on a Mercedes-Benz?
This warning message alerts drivers that the front or rear brakes have worn out and will need to be replaced. The error message appears when the brake pad material reaches its minimum thickness, indicating the pads must be replaced as soon as possible. As the brake pads wear down to a minimum thickness, the wear sensor inside them contacts the rotor, triggering the warning message. Ignoring this warning message can further damage the braking system and decrease performance, so it’s important to address the issue as soon as possible.

How do you check brake pad wear on a Mercedes-Benz?
When inspecting brake pad wear on a Mercedes-Benz, it is often unclear which pads need replacement. We recommend starting by checking your front brake pads, because these are the ones that usually need to be replaced first, as they wear out faster.
There are two methods to check which brakes need to be replaced. One method is to use a Mercedes-Benz scanner and read the fault codes. The YOUCANIC scanner will indicate whether it is the front or rear brakes. You may notice that one set of brake pads is worn more than the other.
In some cases, the brake pads may not wear out evenly. The outer pad may have plenty of life left, while the inner pad is completely worn out. Check the inner brake pad, not the outer one, since the wear sensor is also installed in the inner brake pads.
How do you reset the dashboard warning message?
The Mercedes-Benz check brake pad warning message resets automatically once the old brake pads are replaced. There is nothing extra you need to do to reset the warning. If you don’t replace the worn brake pads, the message won’t reset.
I changed the brake pads on my Mercedes-Benz, but the warning message is still on in my dashboard.
There are two common reasons why this warning doesn’t clear after replacement.
1. You did not replace the brake pad wear sensor. Every time you change the brake pads, you must also replace the sensor on a Mercedes-Benz.
2. The other set of brakes is worn as well. If you replaced the front brakes and sensors but are still getting a check brake pad wear message, your rear brake pads may also be worn and need to be replaced.
Other issues that could be preventing this warning message from clearing could be damaged modules, connectors, wires, etc. Still, the most likely scenarios are that the wear sensor wasn’t replaced or another set of brakes is also worn.
What is a Mercedes-Benz brake wear sensor?
This sensor alerts the driver that the brake pads must be replaced on the Mercedes-Benz. Depending on the Mercedes-Benz model and year, the wear sensors are designed to break or complete a circuit once the brake pad gets worn out enough for the sensor to contact the brake rotor.
Can I drive a Mercedes-Benz with the brake pad warning on?
Once the warning message comes up, you typically have about 200-400 miles of life left before they need to be replaced. If you go past that point, the brake pads will wear completely. In addition, check brake fluid level warning may come on if brake pads are not replaced on time.
Do all Mercedes-Benz wheels have brake pad wear sensors?
No. Mercedes-Benz cars typically have only two sensors, one per axle. Typically, there is a brake wear sensor located at the front left wheel and another at the right rear wheel for the rear axle.
Can I reuse my old Mercedes-Benz wear sensors?
No. Once the brake pads wear out, the wear sensor insulation will be damaged. The sensor cannot be reused once the insulation exposes the wire underneath.
If you replace the brake pads before the warning message appears, you can reuse the sensor in those cases. We hope you find the Mercedes-Benz Check Brake Pad Wear Message guide helpful. Check these troubleshooting and repair guides for more help on your Mercedes-Benz.
