How Often Should Mercedes-Benz Brake Pads Be Replaced?
2 Answers
Mercedes-Benz brake pads are not replaced based on mileage. Generally, they need to be replaced when the brake warning light comes on. Additionally, you should check the thickness of the brake pads; if it is below 3mm, replacement is usually necessary. Here are the methods for inspecting brake pads: 1. Check the thickness: A new brake pad is typically about 1.5cm thick. As it wears down through friction, the thickness gradually decreases. When the visible thickness of the brake pad is reduced to about 1/3 of its original thickness (approximately 0.5cm), the owner should increase the frequency of self-inspection and be prepared to replace it. Some models, due to wheel design, do not allow for visual inspection, and the tire must be removed to check. 2. Listen for sounds: If a metallic scraping or squealing noise is heard when lightly applying the brakes (this could also be due to initial break-in of newly installed brake pads), the brake pads must be replaced immediately. 3. Feel the pedal response: If you notice that the brake pedal feels harder to press and requires deeper application to achieve the usual braking effect, or if the pedal position feels noticeably lower during emergency braking, it may indicate that the brake pads have lost most of their friction and must be replaced.
I've been driving a Mercedes for several years and found that brake pad replacement doesn't have a strict deadline—it largely depends on personal driving habits. For example, since I do a lot of city driving with frequent stops at traffic lights, the wear is faster, and I might need to check them every 30,000 to 40,000 kilometers. Mercedes vehicles come with wear indicators; a sharp sound when braking is a warning. If you drive more on highways, the wear is slower, but at least have the thickness checked by a technician during your biennial maintenance. If the thickness is below 3 millimeters, it's time to replace them. Otherwise, grinding down to the brake disc can cause damage, and the repair costs could be several times higher. My advice is not to wait strictly by mileage—pay attention to driving sensations. If braking distance increases or feels abnormal, address it promptly. Regular checks at the 4S shop are more reliable, and Mercedes OEM pads offer excellent quality for safety and peace of mind.
