Dead easy mate - wheel off, undo bottom 13mm bolt (on bottom slide of caliper), remove wear indicators (these will probably break), swing carrier up, pads out, new pads in, swing carrier back down, fit new 13mm bolt (should be new ones in with new pads) and torque, fit new wear sensor, wheel back on.  Don't forget to pump brakes till pedal hard.

New sensors do NOT come with pads - you will need to buy seperately.

15 mins a side.

HTH :y

Get Vx pads mate - found pattern pads no good for front but ok for rears.  Fronts around £14 on TC

If you have any problems with push the pistons back, use a G-Clamp with an old pad and gently tighten it...

I normally just make carefull use of a large screwdriver with the old pads still in place to push the pistons back.  Take care on the edges of the discs though....   :y

Also, ensure that there is sufficient space in the fluid header tank to take the displaced fluid or crack open the bleed nipple to expell it.   ;)

...oooh.sucks teeth and shakes head...if they are that stiff there is a problem, make sure the fluid has somewhere to go with the res cap off or the bleed nipple open as mentioned, also possible a dust or fluid seal is damagad and jamming the piston.
 G clamp will most certainly do the job but last resort imo, you need to feel whats going on. Special tools for this work on a similar basis but for the omega these should not be needed ime.

 There is a block moulded into the back of the caliper that can be used with mole grip jaws to sqeeze the piston back in if it does get stuborn, but you should be able to sqeeze the caliper over on its sliders by hand while still mounted if all is in order. It will be stiff but possible, just.... :y

Now I would ALWAYS open the bleed nipple before pushing the piston back, massively reduce your chance of reversing the master cylinder seal.


gets rid of the oldest most knackered fluid too.

obviously bleed brakes as well when you are done, make sure your are rid of any air.

And the guide is in Maintenence Guides, also includes changing discs (just ignore those parts if you're just doing pads)

I believe that is incorrect for pre 1998 2.0l which use different sensors, not on TC

just my 2p

always buy genuine pads/discs, pattern pads will start squealing in no time and will probably deteriorate quicker. i learnt this the hard way.

also buy genuine wear sensors, i bought mine from vaux-parts and thought they were original parts but weren't and didnt fit.

edit: come to think of it, maybe they were genuine but didnt fit because my pads were pattern  :-[

vauxhall pads every time now...no smell coming down pyranees, pattern parts previous year were stinking. Discs ,...ferodo have seemed ok. Sensors they break but got some from vauxhall world parts at a reasonable price.
