I'd fit Vauxhall via Trade Club just because they are cheap enough on the TC scheme. Make sure you fit vented if that's what's already fitted (which I think will be fitted to your car)  :y

Sorry, I've never had need to buy the rears, but if as cheap as the fronts won't be much different from pattern part prices. I've just tried to log into the Trade Club, but getting an error  :'( :'(

Yep that TC website is a load of krap!

Personally guess that pattern discs ok for rear as they don't do too much work - I've always used pattern pads on the rear without any problems and TC pads (and discs) on the front.

I see your thinking, but what's the price difference of full retail price of pattern discs & discounted OEM discs?  :-\

How much are pattern pads? TC rears are/were around £20 .................. My R Class's rear pads are all but £100 from MB  :o :o :o

Pattern pads for the rear, incl pins and springs, were about £12.  Used them on last 3 Omegas without issue.  (saving about £24 in the process - not to be sniffed at - bought me getting on for 1/4 tank of petrol in the Jag  ::) )
Similar price to your Merc for rear pads from Jag - pattern (Pagit or Mintex) around £25

Never had to replace rear discs on Omega so don't know prices - shows how little work they do ;)

Pattern rear discs are significantly cheaper than VX, changed mine twice now, but wouldn't like to say if genuine would have lasted longer :-\ car has done over 150k in my hands...

Rear pads can be got for next to nothing, but even genuine pads aren't expensive :y

Just bought a set of genuine GM vented rear discs from Archie Moss via ebay, as existing heavily scored and corroded..found genuine at £105=00 delivered..genuine pads/shims/pins at £9=50 a set

Not sure how far of those prices are on TC but saved me the journey and delivered to my door inside 2 days

from memory, rear vented discs are abou £75 + vat a pair.

Rear pads and discs get a right hammering if you use traction control much.

I find Eurocarparts good for brake parts. very good prices. I always check TC price first and then ECP.  :)

I like the pagid stuff.

but then I do drive like a grandma..... wouldn't have a clue what to buy if you needed performance.

out of interest OP do you definitely have vented?

Hmmmm.  Rear brakes are obviously a vital component when it comes to stopping, but I'd worry less when it comes to the rear than the front.  I'd not lose sleep over fitting cheap pads on the rear, but discs???? I'm not so sure.

I have no doubt others will testify that Aftermarket cheapies are perfectly acceptable, and I'd happily bow to their experience, but for the difference in price (when you consider you are changing the discs for the final time in the cars life)... why bother?

I'm with you there, decent quality, right price and dead easy to find.
Last year I paid £60 over the counter for the solid rear discs, pads and some brake cleaner.
Hell, the Canter I drive every day has had Pagid pads in it for the last 40,000 miles.

Those in the (not)link are SOLIDS, of no use if your car is currently fitted with vented rears :y

To fit them to a car that should have vented rear discs would be monumentally and criminally stupid :y

I don't doubt Audi discs and pads are expensive. :)

As for the TC pads I was clearly ripped off by the dealer then cos when I bought front pads and discs on TC and took them up to martin's to help me fit them (back when I couldn't even change oil by myself  ;D) they were more than that. on the TC site but it wont show prices for some reason.

Charged retail? Last time I bought a set, was around £75+ vat, although that was around a year ago. Think it's more £85 + vat now.

Try Ford, Fiat, ect, all similar prices. Vx are no worse than any other big dealer.

One key thing stopping me switching to Jag or Audi, is lack of access to trade parts.

Yeah, sounds like it. Also recall posts here about pins/calliper falling out as vented are much bigger. So when the solid one wears, the calliper can fall out  :o

Fixed :y

Pads held in by pins. Pads same across the range, but vented discs have a wider caliper with longer pad retaining pins and a wider anti rattle spring :y
Title: Re: rear discs
Post by: Andy B on 14 August 2013, 22:52:41
ToledoDude
You need to check that your discs should in fact be twice as thick as what you already have fitted ie you seem to have solid discs fitted when you should have vented discs fitted. If so you are in danger of losing the fluid from the rear brake circuit as & when one of the pistons (can't remember which - I have solid discs  ;)) runs out of caliper as the pad wears. Net result is that you have half the brakes you should have!

Vented disc calipers have an 'extra' section about 12mm wide between the two halves :y might also have 42 stamped on the outer piston side :y

Are the calipers definitely not wider? Solid discs have a 2 piece caliper, Vented have 3 piece calipers.

Ideally need to get the wheel off to double check...

Incorrect, *ALL* Omega fronts are vented. Pre 1998 2.0l have a smaller diameter, but remain vented.

All post 2001 V6 (so all DBW V6) have vented rears when they leave the factory.

Where is the disc relative to the middle of the caliper? If you have the correct disc fitted to the correct caliper, the disc should be more or less central to middle of the caliper. If you have a solid disc fitted to a vented caliper, then it will be offset to one side ie the difference in thickness between the solid & vented disc.

Are you sure you're not confusing solid/vented discs with those that are cosmetically crossed drilled?  :-\
Title: Re: rear discs
Post by: 05omegav6 on 16 August 2013, 21:19:09
Put another way, pads are about 15-18mm thick when new discs are 12mm solid and 18-20 vented.

If you can get your pinky between the caliper and the disc, then you have the wrong discs :y

After seeing an episode of "Fake Britain" a couple of weeks ago on pattern car parts, I would be loathe to buy anything that didn't come from a reputable manufacturer.

Part of the episode showed a pattern disc being tested and it failed catastrophically after being subjected to heavy braking from 50mph, the failure was the brake disc itself simply breaking in two and coming away from the hub  :o

Sounds a bit confusing I am right in saying that you can only have a problem if you combine a solid disc and a vented caliper and that the pads are the same for solid and vented discs. I also assume that you could not fit a vented disc into a solid caliper.
