My wife drives our 2017 C200 most days, and last night she told me the brake pedal feels softer than before and there is a high squeak when she slows down near the roundabout. I did not take it seriously at first because she always says the car sounds funny. But this morning I drove it myself, and she is right. The pedal goes down a bit more than I like, and when I stop gently there is a thin metal sound, like a small whistle. There is also a lot of black dust on the front wheels, much more than the rear ones. The car has around 68,000 kilometers, and honestly I cannot remember the last time the pads were changed. My friend says Mercedes pads wear fast because the car is heavy and the brakes are strong, so it might just be normal. My brother in law says to ignore it until the warning light shows up on the dashboard. That sounds risky to me, since we take the kids to school every morning and sometimes drive on the highway to see family. I did some reading and found a page about Mercedes brake pad service from a workshop here in Dubai. It explained how the pads, discs and sensor wire work together, and how the dashboard light only comes when the pad is already very thin. That surprised me, because I thought the light was an early warning. I do not want to wait for it. Since we live close to Al Wasl, I typed Reliable Mercedes brake pad change serving Al Wasl into my phone, mostly to see how long this job takes and what the usual price range looks like. All I found were offers, no real stories. So I wanted to ask people who own these cars. Do you change front and rear pads together, or only the ones that are worn? Is it normal for the sensor to be changed each time, and does that cost extra? Also, how do I know if the discs are still good? One person told me that if you feel a shake in the pedal, the discs are bent, but mine does not shake, it only feels soft. Could a soft pedal mean old brake fluid instead of pads? Another thing is the parts. Do you pick original ones, or is a good quality brand fine? I have heard cheap pads can be noisy and make even more dust. If you did this on your Mercedes, please tell me how long you waited, what you paid, and whether the brakes felt different afterward. Thanks a lot, I will check the replies tonight.
