Had a scraping noise coming from the nearside rear wheel on my 2000 V6 2.5.
When I took the wheel off, I could see that the friction surface had completely come off one of the pads (the outside one if that makes any difference), so the backing part of the pad has been rubbing on the disc and has caused pretty bad grooving on the disc. I can see that the friction surface on the other pad has cracked as well. I haven't had any warning on the dash.
I drive pretty smoothly and the only 'abuse' the car has had has been leaving it to sit for extended periods without any use. The car has been serviced mostly by a VX dealer (although recently on an 'all makes' service, not a VX schedule).
The discs and fitting kit are badly rusted, so I'm planning to replace discs, pads and fitting kit. However, I would appreciate any comments on the following:
* Should I be worried (beyong the obvious) about a pad failure like that ?
* Shold there have been a warning on the dash (ie has there been a sensor failure) ?
* Can anybody recommend a good (ie quality but not too expensive) source of disks, pads and the fitting kit ? (even my local VX dealer group can't supply the fitting kit).
Thanks.

The rear discs don't do a lot to stop the car, so I would not be too worried about getting the best replacements. The discs themselves may have grooves, but are you sure they have had it?
I don't think the back ones have sensors, so no warning lights.
To be honest, I don't understand what you mean by a "Fitting kit".
-
1, They could obviously do with being inspected more often, makes you wonder what else they're not checking on a service.
2, No pad sensors on the rear so no warning displayed.
3, VX discs and pads are reasonably priced if you get a trade club card, Ask VX to look up 9192128 for the fitting kit.

Thanks for the reply. TBH, I still haven't 100% decided to replace the disks (especially as pads are so cheap in comparison - I could happily trash a set of pads before replacing the disks and it's only 1 of the 4 surfaces anyay ).
The 'fitting kit' (maybe I've got the terminology wrong) is the pins and springs that hold the pads in place. For all I know, this could be standard across many vehicles, not specific to the Omega. I could reuse the ones I've got, but they are pretty manky.

When you do the job make sure the pistons are not sticking/seized (should be obvious as you retract them to fit the new pads) and open the bleed nipple rather than just push the fluid back up the lines as it can invert the seals in the master cylinder causing poor braking.

Hi
It can also cause havoc within the ABS control unit which can be very expensive to sort out.

Thanks.
And there lies the problem!
Mine was laid up for say two weeks at a time, and this contributed to the rear brake pads seizing.
There lots of crude gets caught up in the rear calipers and needs to be stripped and cleaned, bet that's the problem :y
New pins and springs can be had from dealer or independant. Can be expensive from dealer though.
Also check caliper as said, mine was ok.
Yours must have been seized for a while :(

Thanks for the comments. I'm hoping the caliper pistons aren't stuck - I've done that job before and didn't enjoy it much ! Still trying to get the second pin out - probably need to invest in a proper punch.

I have a decent punch, before I used a cut down nail. Thanks for the fitting kit info, should have realised.
