breaking K reg shortly

Anybody know which is the correct size of brake discs for my car?

I own a 1996 N-Reg 2.0 16v Ecotec, and I need to replace both front & rear discs & pads.

Autovaux's sells different sizes of front disc for 2-litre cars : 256x24mm or 288x25mm. Which size do I need? (I'm guessing the larger discs are for the turbo?) My existing front discs are vented, but not drilled or grooved. The rears are not vented.

I'd be really grateful if anybody has the part numbers for the original Vauxhall pads & discs etc, so that when I buy from Autovaux or Halfords etc, I can be sure I'm getting the correct compatible items.

Thanks for your help guys!

256x24mm for the 16v mate - the 288's are for Turbo's and V6's.

Top info guys, thanks. Now I just need to sort out the rears-

The Haynes manual says that the rear discs are 260mm, but Autovaux only sell 270mm rear discs.
I've seen both sizes on sale (<a href="http://www.speedways.co.uk/shop/index.html" target="_blank">http://www.speedways.co.uk/shop/index.html</a>) but I'm guessing that the 260mm are for the 8-valve.

So is the Haynes book wrong, and do I need 270mm?

Cheers

Hi Dave,
260 mm for all calli's, the 270mm are exclusively fro the 4x4 turbo.

HTH :wink:

Surely 270mm are also on the V6 as it shares the same brakes as the Turbo.

Hi Smurf,
I checked my Opel /Vauxhall Technical Information System (TIS) and it stated that only the turbo has the 270mm rear disc's. :?

Smurf I stand corrected I checked other websites and they state the rears for the turbo thru to the 16V are 270mm. [img]/smile.gif[/img]

Sorry Dave for providing the wrong info. [img]/sad.gif[/img]

So which models use the 260mm rear discs? Is it just the 8-valve?

Hi Dave,
Sorry Dave im not sure, about the 8V. (Is it relevant?) :roll:

But the 16V has 270mm rear and 256mm fronts. [img]/smile.gif[/img]

Thanks for all the info guys, I appreciate your help.

These are the brand new front discs I bought on eBay for just £40 (for the pair):

<a href="http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=4505305198&ssPageName=STRK:MEWN:IT" target="_blank">http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...me=STRK:MEWN:IT</a>

The auction closed on Saturday night and I received them on Tuesday morning.
I'm pretty impressed with them especially cos I'm on a budget.
