I have a 04 Mercedes C230 Kompressor Sport Sedan When I step on my brake my car shakes especially when I'm in sport mode And also the brakes sometimes squeaks too when I step on them?
If the car shakes when you press on the brakes, you probably
have warpped brake rotors, and the squeak is probably some worn out
front brake pads.
I would have your rotors checked and either replaced (which
Mercedes highly recommends or re-surfaced)
