These cars do also have brake wear sensors that should in principle alert you via a dash warning light before the pads get too thin. And also, if you have the original owner's manual and booklets, there should be a flat "tool" in there that you can stick between the wheel rims to measure the brake pad thickness.

Mine had brand new pads installed by the selling dealer when it went through the CPO process. Immediately after I took delivery I swapped out the pads for a set of carbon ceramics. Reduced the brake dust by about 90%. Also installed new wear sensors on all 4 wheels. A friend and I did the installation in his garage since he has a lift. Very pleased.

Yes, as I recall there was a sensor on each wheel but I could be mistaken and there may be one for each axle. There are several vendors selling PowerStop. I used CARiD because I had a discount code and they had them in stock.

Before I took the plunge and put the AMG Ceramic Composite brakes on my SL450, I tried ceramic pads on the original system. I got them from Porterfield Racing Brakes in Costa Mesa, CA and they were great. Significantly less dust, excellent feel, no squeaking, etc. I highly recommend them.

Streamliner Are you saying that only the pads were upgraded to ceramic? No need for the sensors, rotors, etc. to be replaced? I'm hoping this is the case as I would much prefer this route vs having to replace the other parts! And, do you recall the approximate cost?
