I think this means the pad at one wheel has worn thin enough that the wire in the pad wear sensor is exposed and each time you press the brakes, the wire grounds against the brake rotor and triggers the PAD lamp. If I'm not mistaken, on the later XJ40s there are only two wear sensors, one on a front wheel and one on a rear (maybe at opposite corners). I was able to repair our sensor with a little J.B. Weld epoxy to re-seal the exposed wire. If the body of the sensor is damaged so it won't stay clipped into the new pad, you can use the J.B. Weld to adhere the sensor in the pad. I did this for several pad changes before I finally decided to replace the sensor before our son took the car to college.
BTW, if the PAD lamp remains illuminated, that means the wire in the wear sensor has worn completely through and the circuit is open. That happened to our sensor too, and I just soldered the wire together, resealed it with J.B. Weld and used it again.
Cheers,
Don
