Hi, I've fitter new discs and pads all round on my 3.2 but the rear discs which have pins and a spring to hold them in, my parts supplier cannot get them and say they are available from Vauxhall. Has anyone sourced them elsewhere? Thanks :)
-
They've been Vauxhall only for some time.
Availability isn't good.
And then there's the price; ensure you're sitting down when you order them!
There are many threads on this, with several suggestions on how to produce your own parts to get around the cost/availability problems.

and you have fitted vented discs at the back! ;)
It's been known a few times where garages have fitted the slimmer solid discs from earlier cars.

GM# 9195055 (Opel KAT 05-42-801) are the pad retaining pins for vented discs and are 86mm long. Pins for solid discs are 74mm.
GM# 9195056 (Opel KAT 05-42-913) are the anti-rattle cross springs for vented discs and are 56mm across the horizontal span. Solid disc cross springs are 48mm across the horizontal span. And that's because although the pads are the same the vented disc is 20mm thick vs 12mm for the solid.
There is no, and never was, any GM fitting kit for vented discs that included these pins and springs. Only the individual parts.
Likewise there are no 3rd party aftermarket fitting kits for vented discs. The ones advertised are all incorrect. They're for solid rear disc Omega Bs or they're Vectra/Calibra/Carlton/Omega A parts.
You need to find a Vauxhall dealer with a parts department who can place a special order in Germany. Payment upfront, no returns unless faulty and will take about a week, if the pins and springs are still available. Don't expect much change out of £50.
Your existing pins might clean up and be reusable. The cross springs usually corrode at the brass rivet and fall apart.

Vented fitting dimensions here...

It has since been demonstrated that aftermarket vented kits listed are for the Vectra B with 18mm discs, so ignore those.
The last complete set I bought was around 8 years ago and little change from £50 for 6 parts.

I beg to differ slightly on this point.
Rear brake pad kits 9195058 were supplied with vented pins and springs included, but have been unavailable for some considerable time. The last set I got from Vauxhall only had 3 pads in the box, so I got them for a ridiculously cheap price as they couldn't sell them, but I bought them purely for the pins / springs. Why only 3 pads, but I wasn't complaining. I have managed to get several other sets of 9195058 kits since, all old stock from Vauxhall, all with pins and springs included.
I don't think there are any kits left now anywhere.

The last couple of kits I got were from Germany so worth checking on the usual Ebay.de, but I wouldnt expect much luck.

A check on Ebay shows a set of 9195058 listed in the US, although there's no picture or description (bit crap really), so I'd check before purchase exactly what you'd be receiving for your £35.86 (plus any possible import taxes??). One way of getting the vented pins and springs I suppose, with OE pads thrown in as well, rather than aftermarket.

how do you ever wear out or break the locating pins? I had the same type of pin on Opels/Vauxhalls for years on the front & rear of my cars ..... a pin with a barrel shaped 'spring' that held the pin in place. I removed them & replaced them with a wipe of copper slip without problem. The cross shaped clip though on top did rot out.
-
All depends how the car is used/maintained.
Omegas have been cheap enough not to bother servicing for at least a decade :-\

but even so, they just sit there in the caliper ... how do you break them such that they need replacing?
-
Having to batter or drill them out of the caliper...

The most simple set up I've come across are the pins on my TDM ... they look like a wire nail & held in place with a small R Clip .... i really can't think what they're like on my Merc & Smarts :-\

That's how the front pads are held on the Mk2 Granada. Loose fit, but zero hassle.
Both ends of the Barge are a variation of the Omega rear set up... Fronts use two pins and a spring, rears, one and a spring. Fitted new kits when I replaced the discs and pads as they weren't in the best condition ;)

Simplest is a long split pin: push through all four holes and spread the ends. Just like Millions of Girling callipers.

That's how the LC rear pads are held into the AP calipers. But VX seemed to have specced the crappiest grade of steel for the split pins, and they rust to hell and back making it quite difficult to extract them. Many of us have switched to A4 stainless pins. You also don't want to spread the ends apart too much because you need to close them up again to get them out.
Never really had any problems with the Omega pins though. A sharp smack with a medium hammer on the correct size drift and they're out. Clean and grease them up and they're good to go again.

You could close the ends, straighten the pin and either drift it out hoping you don't bend it, or pull it out with some mole grips hoping it all stays in one piece. Then there's the easy way; cut out the middle section with some side cutters and watch the retaining ends fall to the ground.
I agree with the Omega pins, but you're unlikely to be the first person in there. And there are lots of mechanics who can damage anything.

The split pins usually have one longer end 'tail' than the other. This makes drifting them out a problem because you're belting just one side of the split, and it tends to fold over. Also the middle bit of the cheap VX steel pins tends to rust, and become bigger than the hole that you're trying to get it out/through. You can't really get mole grips on the eye end because access is a bit restricted. However, ultimately it's not the worst problem to overcome, and at £4 for a set of SS pins the issue can mainly be avoided in future.

Plenty of owners (including me) who are fully qualified when it comes to damaging things too. ;D
