As they fit like a jack plug, first stage goes in and then second stage needs a firmer push but if yours are dropping all the way in it would appear that the sensor pin is too small as Lizzie said. :-/

That is probably the problem ::) ::)

The number I quoted is definately for your 2.5 V6, as that was the ones I fitted for my dear departed example of that model ;) ;)

Would have thought that you could always glue them in with a wee gob of araldite?  Its really the thickness of the backing plastic thats the most important for when it wears down as the pads reduce....

I have used the old sensor wire in the past.  Simply remove the remains of the old sensor plastic then strip pack the plastic covering and short out the two wires.

When the disc wears down the plastic of the sensor it cuts the wire, breaking the circuit, thus activating the warning on the dash.  Bridging out the wire fools the car into thinking its still all OK.   :y

I used a resistor on my Senator when the discs were too worn to accommodate new sensors.  Can't remember the value but all you have to do is measure the new sensors or an unbroken old one.

100 Ohms springs to mind but it's only a distant memory.

I also remember the sensors being pretty loose with factory parts.  Didn't quite fall out on their own though.

Twisting the wires together as H21 says above is quite sufficient.  ;)  ;)  ;)
