I once had disks and pads replaced by a local garage and years later
when replacing the pads myself found that the low pad wires had not
been connected - they had been neatly coiled up and cable tied
safely out of the way.

Most brake pad warning systems show an error if the sensors aren't

That may be true of more sophisticated cars but the two Fords I had
about 10 and fifteen years ago simply had a single wire that was open
circuit until the pad contact wore down to short it to earth. So they
had no idea whether they were connected.

The connector between the sensor and the loom usually has a link in it. No
sensor connected, no circuit. It's like that on my ancient Rover. Most
modern ones have a loop as a sensor.

The Ford ones didn't. It was a one pin connector. And the pads were normally
o/c. No resistor or anything, apart from the pads not having a reliable earth
path anyway.
