I am NEW to the Benz world. I just purchased a 2001 C320, reading several threads on here I am a bit worried I have made a bad purchase. I have already delt with the seat issues and now my brake lining light has come on. Is it as easy as jsut replacing the pads and sensors? How much should that cost me, labor not included?
Hope you are at least enjoying driving your C320, because as you may find with owning that car, performance will cost you some time, energy and $. Performance cars in general have never been made to preserve their replaceable parts (ie brake pads, suspension components, etc).
Your '01 C320 is certainly not a Honda or Toyota in terms of parts replacement. But then, it should drive a hell of a lot better than most Honda and Toyota cars...
I have done a fair amount of work on my GF's C320 wagon, but I have to say that with a few small exceptions, the car is a pleasure to work on. Well built components, sturdy hardware, etc. make doing something like working on the suspension much more pleasant.
Before diving into this work - are you comfortable and confident working on a brake system? Remember this is quite possibly the most critical system in your car to your safety and the safety of other drivers.
Depending on your mileage, you likely need to replace your front rotors with your pads. OEM Mercedes rotors CANNOT be turned/resurfaced. I definitely had to replace the front rotors on mine - they were cupped really badly, and the new pads would not have made contact except for at the outside edges.
Plan on $200-250 for the whole front job - depends on where you buy your rotors, and what grade/type of pads you buy. I recommend you buy your rotors locally so that you can return them easily if they aren't exactly right. Check your rear pads too while you are at it. They don't wear as fast but may still be due.
Make sure you have all the tools you need to do this job before you begin. Also, something that is often overlooked in this job - crack the bleeder screw valve before you press your calipers in to set the new pads. You don't want to push that old fluid back up into the system. Also, you should bleed the brake system fully when you are done with this job (search this forum for the procedure), and again every 2 years.
