Mercedes 560 1985 the light between the battery and brake light comes on when appling the brake?

Answer 1

That light coming on when you apply the brakes is your brake sensors, from the front brakes, telling you that it's about time to replace the front brake pads. You still have some time to replace the pads and sensors, maybe a thousand miles would be my guess. Depending on the wear on the rotors (check the lips on the outside edge of the rotors) you might only need to replace the pads, and not the rotors. It's not recommended to turn these rotors, but replace them. It's cheaper to just swap the rotors. You can pick rotors up for under $40.00 each, and pads for around $35.00. Sensors are under $10.00 for the 4 you need. And then the brake grease to apply on the back of the pads is only a few dollars. So for around $125.00, you can have a front brake job, providing you're doing the work yourself. If you take it to a garage, it will cost $3-350.00. Dealerships will probably charge you at least $500.00.
