SOURCE: brake warning light is on for 2002 bmw 745i.
The brake pads have sensors in them, when the pads get worn down to the sensor the light comes on letting you know its time to replace. this happens well before the pads are completely gone to reduce wear on the rotors. You should have the brakes replaced and the sensor also.

Hello , check the airbag contact sensor behing the grill assembley . They are located to the left and right of the grill almost to the headlight assemblies. Check the wires to them for corrosion and damage. Check the fuse as well. There should be an air bag testing wire or fuse in the fuse panel. DO NOT UNPLUG THE AIR BAG SENSORS OR HIT THEM !!

Hi, the BMW SRS light can mean any number of things from serious to minor. Sometimes it's alerting you to the real need for a repair of a broken part, but sometimes it is merely indicating that a circuit critical to proper SRS operation was temporarily disconnected (i.e. while you were installing a stereo, alarm, racing seat or steering wheel). You're stuck staring at your SRS light light until you have time to go pay someone to diagnose and reset it or else you have to purchase a R5/SRS, that will be used to determine the cause of the SRS light coming up before proceeding to fix it
Examples of common situations that cause the airbag/SRS light:
If the airbag (SRS) light is on then it means there is a problem with the system. Working on the SRS can be very hazardous. For this reason I suggest you have this looked at by a professional. This is not a DIY repair. Far too dangerous for a novice to attempt to repair.
