I am needing to overhaul the rear brakes on my 3.2 saloon with the vented rear discs. Does anyone know of anywhere that sells all the parts? I'm needing discs, pads, pins and springs. While I have it apart is worth doing the shoes as well?

I would, they're probably original and near the end of their life. Mine didn't survive removal of the disc, which meant another trip to the factors for replacements. Now, I would spend the £20 up front, as I hate interrupted jobs.
It's just the pins and springs that are only available from Vauxhall, everything else can be sourced from all the usual places.

Thanks Nick, I've seen the discs and pads in various places. Good to know about the pins as that was the struggle. Would there be any merit in changing the callipers in order to fit solid discs?

Seems a bit drastic for four 6x80mm pins :o

There is method in my madness! The callipers look quite worn, so my thinking is get a pair of callipers for solid discs, clean and refurbish them, then replace the callipers on the car. There is also much greater choice in the solid discs and fitting kits.

Are the vented ones not required due to the way the TC uses the rear brakes on those cars? Depends how you drive I guess....

That's a lot of parts and buggering about just to paint a pair of calipers you already own. Have you been eating cheese before you go bed?

Fair enough I'll look into the pins and springs from Vx, would you happen to know the part numbers by chance?

9192128 Around £80 from GM
Im still looking for that pallet Nick spoke of ;D ;D ;D

Them springs have shot up in price, just refurbish what you have

The springs on the car are shot, 80 quid for two small bits of metal!!! I can get two callipers for 30 and a fitting kit for 7 quid. The other option I have read about is to replace the pins with split pins, it's the springs that are the problem!

Yep the price is a joke for the pins and springs from VX.. thats what they quoted me a few weeks ago...

Havent we got a member with a lathe who would make up a batch of pins to sell to us?

I'd be happy to make a pin that will work. But considering that many members here won't see beyond Vx branded oil or find having to use shorter bolts problematic, I suspect there will be too much whinging to justify a batch that don't exactly replicate original ones.
And as I've said every time this subject comes up; the pins are easy, it's the springs that require some ingenuity.

Nick how did you know that I had you in mind. :y

It also occurs to me that if we cut two pairs of readily available solid-disc pins into correctly calculated long and short pieces, and then Tig welded them back together there would be four pins the correct length. Which would cost a bit more, but would at least look right compared to the knurled/crossdrill&R-clip/O-ring/other-easy-to-make retention method. It would also be much quicker to do :y

This goes to show that BAD** isn't a good idea, as that would require 8pins to make 4 longer ones. But cutting 4(a car set) in half and welding a piece of 6mm rod between is a workable method. And cheap.

I am glad I got you thinking. Now we have to think about the clips. Do any other car maker have a similar system but at a better price. I also wonder if Opel charge the same price as GM. Do we have any friends in Germany.

Yes, that's what I was thinking of. But anyone who receives heavy stuff on pallets throws long lengths of it away, so it shouldn't be hard to find a couple of metres for nothing. A little shaping and a pop-rivet or spot weld and you're done.

Or if you want a heavy duty spring then just strip your rear blind machanism ;D ;D ;D

Mine's an estate. No blind. Not unless I drink far too much cognac.

Omega rear caliper's are a girling unit, similar were fitted to a lot of other cars, Mercedes being one of them, using the same type of fixings.

Back to the pins Nick whats wrong with a pin made from rod with a reduced dia at one end and a hole to put a "hair pin R " for retention.

Mercedes use that system.

Nothing, there are millions of Girling calipers that are retained like that. I suggest a heavy knurl because the part is already in the lathe and it's easy to do. Cross drilling a small diameter is a pain, and requires a second setup however you do it.
