brake lining light on???

[rodrigo]

my brake lining light is on in my 89 325i and i don't have an onwer's manual..what does it mean?

If you do do have an owner's manual get one from ebay or BMW. Regardless of whether you get an owner's manual, get a Bentley if you plan on doing work to the car yourself (which it seems you are).

Like the other members have posted, look at your pads. If they are worn, the pads sit closer together and it trips the sensor. Trace the wires for tears outside and inside the car, etc.

When you get new pads, get the sensors as well ($15). If you just got the car, I'd get new rotors also...new OEM are about $40-60 each.

fwiw if your brakes and the sensors are both fine, there is a good chance the traces in the IP are bad. For whatever reason this circuit tends to burn traces and the light will stay on all the time.
