I think you mean the sensor will have to be "put back in place" - he doesn't need to "replace" it, in the sense of buying a new one

My understanding is that the sensor is a loop in the end of the wire. When the pads get thin, the wire is worn through by the disc and opens the circuit. Therefore, the sensor would have to be replaced to complete the circuit again and turn off the warning light. I think that this is what the dealer does when the brake warning light is activated (after replacing the pads). Perhaps it is possible to solder the tips of the wires together again, but I have not heard of anyone doing that successfully.
Is that wrong? If so, I will edit my previous post.
Thanks for the input.

The sensor wire usually breaks and opens the circuit when the pads get too low. At least that's what happens on my 98. sometimes if you catch it early on you can save the sensor but not likely. If you don't want to buy another sensor you can just take the 2 wires and close the circuit to turn the warning off. At least in the 98-00 models.
gene you are correct and it could be possible to solder the sensor together for a quick fix. how much are the sensors anyway?
btw, i never noticed RHD spec cars have the temp and gas gauges reversed from their LHD counterpart!

I bought 2 from rock auto a couple of months ago for like $7 apiece but i have not installed them yet. If they work and I have no reason to believe they wont I'm ahead, when I first looked for them at the online dealers a couple of years ago they were like $85. I just ended up closing the circuit and taping them up.
