wires going to the rear brakes

[danielson]

so today i get underneath the car to check my speed sensor since my speedo didnt work since i bought it two weeks ago. found a broken wire and fixed the speedo problem. i noticed that there are some wires that go to the rear brakes that were cut or have broken off. i have no warning lights on at all, im wondering what these wires do.

i have a 91 328is.

Could either be ABS or brake line sensors.

i dont think its the abs, the light never turns on other then when i go to start the car. i think its the brake wear sensor, i need to know for sure so i will take a pic tomorrow.

first of all, you don't have a 91 328is, unless it's bored/stroked, in which case it doesn't really pertain to your question. secondly, it's probably the brake wear sensor like you said, is it just two thin wires? are there two wires already going to your rear passenger side, inside pad? i forget what side it is on the front
