Now have to source discs and pads and repair the spring clip.Have seen a genuine set of pads for £59 with fitting kit but seems pricey too me

that's what you will pay for just a VENTED fitting kit. If you can find one.


Solid kits are dirt cheap.

Do you mean fit the disc then bolt on the caliper then install pads?

Nope.

Caliper, with old pads, on the old disc.
Pins/clip out.
Lever the outer pad against the disc until the piston is home.
Replace outer pad.
Lever inner pad against the disc until the piston is home.
Replace inner pad.
Unbolt caliper.
Remove disc.
Service hand brake.
Fit new disc.
Re bolt caliper to torque (never used threadlock personally).
Repeat on other side. 

Nor do I. I appreciate on original assembly it is good practice. but it makes dissembly more difficult. I reuse the original bolts and copper ease the threads.

Which is utter madness.

The original threadlock is sufficient to rehold the bolts, using anything else (except more threadlock) is entirely counterproductive as the bolts could, in theory, come loose.

In reality, I have only had one caliper bolt come undone, and that was on my first car, a Mk2 Granada which used locking tabs on the caliper bolts and in my youthful inexperience I hadn't bent the tabs back after a disc change

Don't most new pad sets come with new bolts with thread lock on them.

The pads are same for vented and non-vented. That said, genuine GM rear pads include the pins and springs for sold disc calipers. Alas not for the vented discs. So that's probably what you saw.

The vented disc springs and pins haven't been available anywhere for years, including the USA. Even on a special order. All of the after-market versions, supposedly intended for vented discs, don't fit.

So your best bet is to post in the wanted section and see if some kindly member can let you have some usable used ones.

Or repair the springs with some short steel pop rivets. Clean off any corrosion and prime the spring first. Use one or two close fitting washers on each spring if necessary. Even if you have to buy a box of rivets it's still cheaper than the cost of new springs, if they were available. The pins can usually be cleaned up with a wire brush and reused.

I managed to get a set of new old stock from somewhere off the internet for springs and pins about 3 years ago.
The pins had clearly seen some abuse, and when getting desperate, a mate with a lathe offered to make some up, from solid bar. Probably silver steel...
It's the springs that would be difficult to replicate without a press tool.

I got a brand new set of pads complete with fitting kit from a member here about three years ago, for a reasonable price.
Couldn't believe my luck tbh.

Any recommended discs and pads?

[Doctor Gollum]

Doesn't really matter tbh. You'll get two pad changes out of the discs regardless...

[johnnydog]

Don't most new pad sets come with new bolts with thread lock on them.

Front pads do for the Omega (sometimes), but rear pads don't. Probably because the fronts are sliding calipers but the rears are fixed.

Any recommended discs and pads?

The last set of discs and pads I fitted (to an Audi and a Hyundai) were made by Comline. Good price, very good quality and fitment. They are coated so can be fitted straight from the box with no decreasing, and it also avoids unsightly rusting of the hub which normally occurs within days of fitting. They bedded in quickly with a great bite and feel. Very impressed with them. One set I used their own pads which are also branded as Allied Nippon, the other I used a set of Don (that's a name from 'old') both with no complaints.
Some on here may look down their noses at them, but for value for money quality and fitment / performance, there is nothing not to like imo.
Others will have their preferences, but I am just giving my thoughts based on my experience of them.

The vented disc pins and springs have been available up until relatively recently - I bought several sets from a local VX dealer in 2017, and then in June last year, some more sets from another small Vauxhall dealer near to me. They weren't cheap relatively, but the parts chap did some digging around and located them. Some parts depts are willing to do more comprehensive searches, and I'm sure there are may be more lurking somewhere - maybe its just whether the parts chap can spare the time to search.

[Doctor Gollum]

Last set I bought for another forum car in 2014 was £45 for the pins and springs.

[gbh]

Apart from Copper grease on the pads anything else I should grease up whilst it's all apart?

[Doctor Gollum]

Read the handbrake guide

[johnnydog]

I would be tempted to clean and very lightly lubricate the pivots of the handbrake operating levers / mechanism in the rear drum. Availability of hese is becoming less as well. They are in two parts and can tend to seize up, although any lubricant should be high temperature and used sparingly otherwise it will just attract brake dust over time. I'd also just grease the return springs  and the hook ends of the levers outside the the rear drums.
