Get out your manual and familiarize yourself with the menu system. You can access the computer system and go in and do a reset while sitting in the drivers seat... but it is always better to understand WHY you have a warning. Your best bet is to take it to an authorized Mercedes dealership and have them look at the fault.
The brake sensor does many jobs. It senses air in the brake lines, electrical problems with the anti lock system, any other systems associated with the brakes. Have your brake system bled and all systems checked before changing the sensors.
you need to have changed the sensor wires, once these are 'broken" the brake lining warning lite will come on. These are usually located within or near the brake pads
hi..Your break light sensor/switch is sticking. It's usually
located on the floor of the vehicle behind the brake pedal.
Spray some WD-40 on it and see.
try this out..
thank u..
rate me..
It is imperative that you loosen the caliper bleed screw BEFORE you push the piston back into the caliper. Failure to do so WILL damage the ABS hydraulics.
The E320 in that year range upto approx 2005 uses an auxiliary battery to operate the brake pump when main battery supply was lost or low. The low battery warning you describe can be caused by the aux battery being low. This battery is a small 7Ah battery mounted under the pollen filter in the engine area.
