Check Hanbrake, Brake fluid level and Clutch fluid level. It could be any of the three.
Replace the brake pads.
Don't ignore the light. It's telling you to have the brakes inspected.
I have a yellow flashing light on whilst driving looks like two eyes (two hoops) I think it is the diesel filter. What do I do to clear it
The brake warning light on a 2005 BMW 325i can be reset by connecting an OBD II code reader. It can view and clear error codes detected by the computer.

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.
Not a complete answer, but check the brake fluid level. My brake light came on and stayed on last year. Turned out the brake fluid was low. Light turned off after I added some and has been fine since. I had the same problem-took it to Mazda and lo and behold the brake fluid cap was actually recalled for not sealing correctly!!!!!????? No notifiaction of it to us whatsoever but once replaced it was fine. Maybe this is this case for you?
