    I have an 05 S4 cab and the idiot who put the new pads and disks on it before I bought it, trapped the pad sensor wire between the caliper and the pad so it wore through. My question is about how the sensors operate in normel conditions. Is there a complete circuit which gets broken when the pad wears down, or when the pad wears down, does it then create the circuit? What I want to do is bypass the warning light but I dont know if I need to stop the circuit or connect it.

    Thanks.

    You need to join the wires together to bypass it. So snip the wires that come from the pad, bare the ends and join together.

    As far as I remember there is a wire which goes into the pad itself and when the pad is worn down it eventually exposes the wire which in turn set the warning light on. I wouldn't use that mechanic again if he can't get a basic job right like this, especially on a nice car like yours.

    I have stripped it down totally and am happy it is all fine, just one trapped wire which is now positioned correctly, waiting for me to bypass.
