[Diamond Black Geezer]

kick the dealer's naughtybits off

ECP i got the kit from and just rang them . They said thats the only kit they do  So told them to change the listings on the site as they dont fit 
Got money back but i have to travel 16 miles to get it when i return them to the local shop 

Anyone got the part number for the pins please so i can order from Stealers

Just ordered them from stealers :

Pins £7.14 each

Springs £ 5.56 each

Only 8 pins available (in the whole world) on order minus mine so 4 left 

Will be ready to pick up saturday so not too long to wait

Nick W how are you going to stop the pins from working out of the caliper you could drill a hole in the pin for a clip retainer.

That's the traditional way, used in millions of Girling calipers. 


The easiest way would be to peen the wide end, and make the narrow end a little longer so you could bend it over slightly. It isn't rocket science.

....
There isn't a single pattern kit which actually fits the Omegas vented caliper.

The end.

Surely the Omega isn't the only car in the world to use this caliper ....... another make/model must use it .....

If you have vented rears, its VX or nothing nowdays.
If they are solid, give AllGerman a shout

I know as far as Vauxhall ...... but surely the rear calipers aren't unique? GM would surely have just picked calipers out of their parts bin

In essence, they are the standard caliper, but with a thicker bit of 'filler' in the middle, over the standard. Don't forget the vented rear discs were an addition to the range only on later models. So the decision to make an adapted caliper over standard (hence why the pads are the same) was clearly taken.

I'm still dubious as to a few thousand (at the very most) cars having calipers that are unique to them.

Pad compatibility suggests different Andy...

Vectra B is a possibility but the discs are thinner, ergo the calipers are also different...

Different being the thickness of the extra section... Will post a pic of said extra bit up later

I had a nightmare situation about 12 months ago when I did mine.
I sent the details (cheers Al  ) of to 2 companies in the hope that they could come up with a "off the shelf" solution to the pins / springs problem.
Sadly after a couple of months. both firms came back to me with the same answer ........... Nothing matching the dimensions on any catalogue or kit. The nearest one got was a pins from a old Alfa Romero so it looks like its VX only or drill the holes out and split pin them in place

I know exaclty where you're coming from Andy, it doesn't seem to match up, in terms of cost v volumes etc. However, all I can summise/theorise is that the rear caliper is different, and the same, at the same time. When whoever it was (marketing) said 'we'd like to boast vented rear discs, that'd sell on the higher performance models', the discs were easy enough to make up, literally add a few mm thickness. You can literally imagine an engineers being given the task, where they have a caliper plonked on their desk, see the modular construction, split it in two, and simply add a thicker bit in the middle. Not dissimilar to the. Spec up longer pins, and slightly different springs, and you've actually made a whole 'new' larger caliper, whilst retaining probably 7/10 of the individual components of the original caliper. Outer & inner caliper casting, pads, hoses, bleed nipple, seals, boots, pistons, bolts are all the same. So from that way round, if there's no 'off the shelf' solution, that makes pretty good financial sense.

Also Vx/Opel spent some £180million facelifting the Omega, which was not much below what a mainstream Manufacturer could develop a whole new car for, back then. Now we know where a few quid of that went!

Hows that work then ? Surely if that was done the pads would not float
