Try taking the battery cable loose. That works for a lot of cars. I've never had any experience with a mercedes. To reset you brake light or any warning on the S430, just hold down the button (a lil black button on the right side on you instrument cluster) and that will do it. The Brake Sensor warning light will reset itself once the vehicle is restarted. Most common problems are 1. You have a bad sensor or 2. You did not replace the brake the sensors were triggering. There are 3 sensors on the S430 One on each front wheel and 1 on the Right Rear Wheel.
Yes, as long as it's not warped or anything. The rotors on my cars are also smooth & not warped and I've never turned the rotors in 140,000 miles. Some people turn the rotors as a matter of fact.
the rotors
You replace rotors when they get too thin, or are warped. They may be to thin to be turned and still alright to use. Rotors do not "have to" be turned to put new pads on.
No they can be turned off the vehicle.
everytime you change brakes you should have rotors turned by an automotive shop or store. They will tell you if they can be turned anymore and if not you will have to buy new ones.
Front rotors warped or out of round. Have rotors turned and that will fix your problems.
The front rotors are out of round or warped, Need to have the rotors turned.
More than likely you have warped rotors. Have the rotors and brakes inspected. If the rotors are not too bad and have not been turned before they can be turned and trued and used again. You will also need new brake pads.

Remove the rotors and take them to a machine shop for inspection. If there is not much damage they can be turned.
