Rear disc size confirmation.
« on: February 06, 2011, 06:53:17 pm »
Hi all,

I'm looking to fit GTI front and rear brakes to my GT TDI 140. I have the full front set up with 312mm discs thats fine.

I'm getting conflicting info on the rears. I was told I could just use the GTI rear calipers and carriers on my existing TDI disc but now I'm not so sure.

I've just looked on E.C.P and the GTI rear disc is listed under 3 different sizes 255mm, 260mm and 286mm.

After searching on here it looks like its 286mm but I'm unsure of the TDI rear disc size as E.C.P states that in 3 different sizes too.

I can measure them tomorrow but thought I'd ask the more knowledgeable on here first  :happy2:

TIA

I have an early 54 plate gt tdi, and as far as im aware the front dics are 286mm and the rears are 255mm, the later gt tdi's came with the same brakes as the gti 312mm front and 286mm rear  :happy2:

I fittd some to mine but then changed them again for the R32 set up!

Awright chaps

TDIs including GT TDI's got either got 255x10 or 260x12 discs

As far as I know NO diesels got the 286x12mm discs from the GTI these were only fitted to 2.0TFSI GTI's and Edition  30's

The carriers will be different and they wont fit, having seen a few hubs I would imagine that putting 286mm rears on a TDI would be doable but you cant mix and match. You cant just upgrade the discs.

The 288mm discs from the front of lesser Golfs are 25mm wide and wont even go in the carrier

Dont forget you'll need I think a 14mm spline bit to remover the rear caliper carrier bolts, as always a straightforward job if you've got the tools

Dave you are a legend  :happy2:

So just to confirm, if I want to use the GTI rear calipers and carriers I have I will need to upgrade the discs to 286mm and these will go onto the TDI hub with no problems?

I have the 14mm spline bit so thats no problem.

Just had a look on ETKA..... im no ETKA expert and there are a couple of different suffixes for rear hubs although the main part number remains the same.

For a 100 quid mod its a risk worth taking, Im almost certain they'll go straight on.

I was looking at a 2008 Mk5 on illustration number 505-05 item 16

True.

Mines a 2005 so maybe different. Im pretty sure they'll go straight onto the hub though.

So if i have read this right get gti carriers and calipers and up grade the discs to 288mm...like these from Awesome

Thanks Andy,

But for my needs def overkill! I just want a little extra stopping power. When its mapped its not going to break any records (about 190bhp) but I feel the stock TDI brakes are pretty poor.

Its the missus's daily driver after all  :happy2:

Yep but they got the size of the rear disc wrong its a 286x12 NOT 288mm.

If you're planning on spending 415GBP then let somebody fit a used set first!
