Complementary Modification: Replace Rotor or disk
Besides physical damage there are basically two ways your rotors can go bad on your Mercedes. The first way is they just wear out. All rotors have a minimum wear thickness on them (that is usually stamped on the rotor). Once they get below this thickness they need to be replaced. If you are going to measure the thickness of the rotors make sure to measure in several places, as the rotor can wear unevenly. The second way they go bad is by warping. If you are feeling a pulsing in the brake pedal when braking, and it is proportionate to the speed of the vehicle you probably have a warped rotor. This is usually caused by hot spotting the rotor by late braking then keeping the pad fully depressed on the rotor while stopped. The heat from the braking trapped by the pad over time will warp a rotor. Rotors can also get heavily grooved. This can also be a cause to replace them.
When replacing your rotors always replace them in pairs. You should also replace the brake pads as well, especially if the rotor was heavily grooved. You want to start with two flat surfaces (the rotor and pad) rubbing against each other when seating the new brakes in. This will lead to better braking performance and eventually longer life from the components.
This is also a good time to give the system a good bleed and get all of the braking system like new.

Tumble Flap Position Sensor Replacement - C Class - W204 - Mercedes-Benz Tumble Flap Position Sensor Replacement Time: 2 hours Tab: $50 to $100 Talent: 2 Tools: T-30 Torx driver, small flathead screwdriver Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Tumble flap sensor Hot Tip: Be prepared to move things out of the way Performance Gain: Working variable resonance intake Complementary Modification: New air filter The Mercedes C350 has a variable resonance intake manifold. This manifold can switch over from long intake runners to short intake runners by utilizing switch flaps and tumbler or flap shafts. There are two shafts, one on each side of the intake manifold. If you are getting error codes from the variable system, one of the first things you should check is the tumbler flap sensor for failure. Both sensors are located at the rear of the intake manifold. While replacement in theory is easy I have never been able to si...
Coolant Temperature Sensor Replacement - C Class - W204 - Mercedes-Benz Coolant Temperature Sensor Replacement Time: 2 hours Tab: $1 to $20 Talent: 1 Tools: T30 Torx Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Coolant temperature sensor Hot Tip: Use a mirror to see the sensor Performance Gain: Proper temperature readings Complementary Modification: Flush cooling system The coolant temperature sensor is located on the rear of the left cylinder head. Replacement is not that difficult but you will be working with the coolant so take proper precautions; first make sure the coolant is below 40 degrees Celsius. Wear gloves and be prepared to catch the coolant and dispose of it in accordance with the regulations in your area. Also even though not a lot of coolant will escape make sure to refill and bleed the system when you are finished. Check your water temperature sensor before replacing the thermostat. Applies to: C350 (20...
Crankshaft Positioning Sensor Replacement - C Class - W204 - Mercedes-Benz Crankshaft Positioning Sensor Replacement Time: 2 hours Tab: $20 to $40 Talent: 1 Tools: T30 Torx Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Crankshaft positioning sensor Hot Tip: Use a mirror Performance Gain: Smoother running car Complementary Modification: Replace Camshaft positioning sensors Your fuel injection computer (DME) may output a code that indicates a faulty camshaft position sensor (CPS). This important sensor tells the car's computer where the flywheel is located in relation to the combustion cycle. The DME takes the signals from both the cam position sensor and crankshaft position sensor, and calculates when to fire the fuel injectors and spark plugs. If the crankshaft position sensor is not operating properly, your car will run very erratically or perhaps not at all. Replacement of the sensor is not as easy as the camshaf...
