Brake Pad Wear Warning Light

[Tony Hoffman]

For that light to go out, those two wires need to be connected together. It
there is an open circuit, it lights the warning. If it's shorted, the light
goes out. The wear sensor inthe pads is just a complete circuit that gets
cut when the pads wear about 90%.

The newer cars (such as the A6 mentioned) only use one indicator, on the
drivers wheel. On the older ones, there is one on each wheel. I keep the
plugs with wire from every set of pads I throw out. That way, I can make a
quick plug in harness if needed, instead of cutting into the factory
harness.
