  Hi,
     When fitting the wear sensors do they have to be fitted into the pad before the caliper is swung over the pads and bolted in place?

  Thanks,
             Pete .

You can clip them in afterwards IIRC.

After mate!

I just changed my brake discs, when I got one of the wheels off I saw a curious white wear mark along the inside of the alloy... One of the sensors had came of and was in the process of being ground out by the wheel

 Thanks for your replies,
  
     When i tried fitting mine after putting the Caliper back on i broke the first one because it simply wouldn't pop into the hole in the pad and the other is in but barely!

    Anyone else had this problem and found a better way?

           Thanks,
                      Pete .

yes!

The omega has two types of brake disc/caliper.  They each have different types of wear sensor and are not interchangeable.

when i changed mine the numpty in parts sold me the wear sensor for the 2.0 caliper/discs rather than the V6 discs (sorry cannot remember the sizes or manufactuers)

I do remember that the wear sensors should be ceramic - cream colour.  the wrong ones were totally black

they should pop in quite easily

I have always found them a right pain and IMHO superfluous for anyone - like most on here - who properly service their cars, and therefore check pads regularly.

I have never been able to clip the sensor in with the caliper and pads fully assembled - always seem to have to nudge the pad out a bit to have room to insert the pin, and then get the pad back in without swinging the caliper back up, which would break the 90 degree bit off..
(difficult to remember exactly without it in front of me).

  Thanks jon & ians,
                            Glad it's not just me then .

   They were the cream coloured ones but still a right pain trying to get them in.
 
  I know there not that important as you say if you do regular maintenance but just wanted a clear check list on the dash computer .

How many sensors are there? VX told me there is only one on the front nearside ( Is the main dealer actually wrong about something )

[ians]

it depends on the age of the car.  There will be only one on yours as the dealer said

Facelifts - one sensor, pre-facelifts (incl mini-facelifts) - two sensors.

To clear check list on the dash computer you just need to cut sensor wires and join together.  Not recommended but does the job & ok if you check visually regularly.

Thanks ians i just bought one . mine worked loose and wore away (speed humps i think) will fit it at the weekend. i find it easier to lift the caliper up then the pad to fit them

  Thanks dbug, if worst comes to the worst that's what i'll do, not going to keep paying £5 or £6 for new cables .

No probs - best to solder and then insulate - cable tie out of harms way

I would unplug the lead or cut close to the socket up in the wheel arch, then short it out neatly, then you've got no loose leads around.
