Pad wear indicators
Discussion
The trick to getting the old ones out is patience and some needle nosed pliers. I did mine a few weeks back. In hindsight, I should have just removed the old ones and bridged the wires together. It is quite easy to see when your pads are worn especially if you take the wheels of your car regularly like I do.

no the indicators are seperate, if you change the pads sharpish you may get away without replacing the sensors, but it is an aquired skill getting the old ones out of the pads!
In which case, surely, once the light is on, the sensor is past it, by definition?
Which bit have I misunderstood?

Nope sorry not true.
The light will come on as soon as the carbon material comes in to contact with the disk, therefore if the pads are changed withing a couple of hundred miles of the light showing, provided braking has been kept light the wire is usually not worn.
The wire runs through the centre of the carbon blocks that fit in to the slot on the brake pad you see.
If you ever do wear one out I wouldn't bother trying to solder it up the wire seems specially designed not to tin lol!

Ahhhh, thanks! The light will come on as soon as the carbon material comes in to contact with the disk, therefore if the pads are changed withing a couple of hundred miles of the light showing, provided braking has been kept light the wire is usually not worn.

Think it might depend what era the car is - mine is a 3.2 '88 and the soldering trick did the job just fine. Maybe later cars are different ?
