What is a brake lining check?
On many vehicles, you can see the brake pad through the holes in the wheel. To check the life of the brake pad, you need to determine its thickness. If the pads look thin, less than 1/4″, it might be time to get them replaced. On some brake pads, you might see a wear indicator slot down the center of the pad.
How does the brake wear sensor work on a Mercedes Benz?
The brake wear sensors have two wires running to contacts embedded in plastic within them. The sensors are triggered when the pads (and thus the plastic of the wear sensors) wear down to the point where the two wires feeding into / out of them created a CLOSED circuit (or short) through the brake rotor.
When to replace brake discs on Mercedes-Benz R320?
That totally depends on your driving profile and style, as well as brake material I just replace the rear discs and pads on my R320 2008 after over 160K km. The fronts have been good since 70K km and will be good for a few more years. I stayed with OEM. But they come on with about 2 mm of pad left. So no big rush.
Is there a brake lining wear warning light?
Greetings everyone. Newbie here with a 1999 E320 that had its brake lining wear warning light just pop on. Had my brakes done once already but can’t remember for the life of me who serviced them.

What to do if your brake line wears a light?
You probably should inspect your brakes and make sure the sensors look ok (seated properly in connector and the pad). There are sensors at every wheel (a wire inside the pad) when the pad wears the wire touches the rotor and the light appears. I would have the pads looked at, some times they do the front or rears only
