Cheers Mr The Bear 

Actually went to three local motorfactors for the stuff, to no avail. Castrol red grease seems to be the right stuff. After much searching on the internet, with may people saying ordinary grease or coppperslip is fine, I've decided to go 'proper' and ordered some Castrol red grease online.

I wouldn't use any copperslip.

This is what ya need . . .

Or the 3M stuff but that's farking expensive . . .

HTH

Cheers mate - seen it, but actually wasn't sure if this was the right stuff as it didn't state 'high temperature' (or missed it on the packing?) but I know what to get now 

[Diamond Black Geezer]

Oh, just to add to the discussion - they came, and they're too ruddy small!!

They're sure these are the ones they have listed for Omega, but what i don't get is that the ones that Seth recommends, and gave the link for claim to be 8mm diameter, and 60mm long - the same dimensions as the ones biggred sent. Now has my V6 got some weird larger calipers that isn't standard (highly doubt this - have stamped Lucas and Opel on them) I will have a go at swapping a slider bolt for one off the Turbo Weasel FL, just to be double double sure they're the same caliper - but if the ones Seth has used before are listed as only 8mm diameter - and the Omega ones are definitely 9.8/9.9mm - how can that be? I'm confused!

8mm pin in a 9.9mm hole might sound ok, but they waggle around like you wouldnt believe, and I can't bring myself to fit them to the car.

It's no use guessing at what need to be reasonably precise measurements.
Get yourself a cheap digital caliper and measure the ones you took off.

[05omegav6]

Be fair to assume that early four pots have smaller, different calipers to match their smaller, different discs and they've sent the wrong ones

But as Nick says, best to actually measure yours

[Diamond Black Geezer]

Have now measured with digital calipers my slider bolts, and contacted the company again. The Omega slider bolts are 71mm long and 9.9mm diameter, with a 17mm head with internal thread of M8 x 1.25. The snag being the ones they offer as replacement, and should fit have an internal thread of M8 x 1.00. So it's a case of sourcing new bolts, or getting them to make a kit up. Their kits come out as almost £30 - including rubbers I don't need, and bolts I don't want, bolts can come from scrapyards anytime. And £30 is almost double the price for the same as what Serek linked to from a similar company. Snag being the ones Serek offered are the same, earlier, thinner slide bolts. So I have no idea where I am or what to do now! 

At present I'm thinking just slap grease on the originals, bung them back in and come back to them at a later date, as slightly corroded slider bolts isn't going to be an MoT fail, but the complete lack of front suspension and fuel leak are, so having to prioritise.

While I've got you all here - anyone see why this won't be a perfect replacement for original Omega brake banjo bolt?

It's a thread of M10 x 1.00, looks identical to me, and half the price of genuine GM, stainless steel and comes with two crush washers, which Vx want 99p each for.

Thanks gents. 

[05omegav6]

This is exactly the sort of thing that should be GM sourced... why? As you are finding, noone else seems to be able to manage any more than a guess...

Presumably VX do a caliper repair/overhaul kit...

[Diamond Black Geezer]

Ah, yes, and no - they want to sell you the caliper carrier too - so well in excess of £60.  Aside from the additional cost of that, I have already spend many hours grinding off the rust and repainting my perfectly serviceable calipers, which now look like new. I only need a rubber gaiter, and a couple of slide bolts to make them like new. 

[05omegav6]

Ok, factor in all the stress and aggro trying to accurately source those two parts and tell me that's not worth £60

If you're to do summat...

[Nick W]

Or just do what the rest of the world does; polish them up, grease and refit. Crudded up brakes are nothing new, and rarely require much to make them serviceable again.

Can't argue with that

But seems a shame, given the lengths being taken to preserve the rest of the car, that such a convoluted approach is being taken

I'd never use copperslip anywhere near rubber brake components. It's an anti sieze compound mainly but attacks most rubber and causes it to swell in my experience.

That's correct. . . Hence why I gave him a link to silicone paste
