Brake wear sensor

With regard the brake wear sensors fitted to the front left and rear right, does anyone know how many wires there are to the sensor, and if the sensor is normally open circuit, closed circuit, resistive or other?

Thank you

Cheers from down under.

It's a two wire sensor which requires continuity to keep the warning light off. When the sensor wears on the disc (and so to ground), the warning light is lit. If either wire breaks, the warning light is lit. If the sensor is unplugged, the warning light is lit etc.

It's possible to effect a field repair and fool the system by simply joining the two wires together and removing the worn sensor from the loop. It will take about 5 ignition cycles to extinguish the warning light.
Cut the sensor off the wire and bin it. Join the two wires and insulate well. Secure the remaining wire so it doesn't flap about and you'll be fine as a temporary fix.

I've repaired my rear sensor like this and it's been fine for the past couple of months. The new one is still in it's box on my desk, the next time I've got the rear wheel off I'll fit it.
$100! Sheesh, I paid about £12 for mine - and thought that was expensive.... :lol:
