NQSBBK - Rear Caliper Swapout Mod

[camfollower]

I've just fitted mk6 Gti calipers on mine this summer,.they came off a late 2010 car apparently. The piston on them is a lot bigger than what was on my mk5 ones and I must say they've made a hell of difference. Not sure if they've uprated them all but when I had to get the lines the lad at VW had to go and look at an ED35 to get the right parts as they weren't on ETKA yet. Nice little mod seeing I only paid £90 for them!

Don't mean to be obtuse here, but if The above quote is correct, why bother with the caddy mod?  Surely it's easier and more cost effective to grab Mk6 rears... Or am I missing something...

You would think that, but I have the MK6 rear setup on my FL VRS, and trust me the Caddy mod is worthwhile, The MK6 piston is the same size as the MK5 GTI 288mm setup, just the caliper/disc is smaller/lighter. So it would be worthwhile, Its probably going to be my next mod when I get the cash together

Cheers for that.  So swgti is either mistaken or perhaps he grabbed some ed35 rears (do they have a larger piston?)

If I was going to be buying some standard mk5 rears, I may as well buy the mk6 ones purely for a slight weight saving..?

I'd like to do the cabby mod, but it's going to be 400plus once everything is painted, bits to fit, delivery etc.

The ones I have deffo have a larger piston so I wonder if they're ED35 calipers, the lad I bought than off hadn't seen the car they came off, he used the fronts and they were identical, maybe the early mk6 had the same as the mk5 and 2010 onwards there's been an upgrade? Also the ones I have are made by Bosch.

Very interesting that mate, thanks... did you happen to measure the piston diameter, standard rears are 38mm as Dave suggests on page1.

Mines is an 2011 car. Bosch rear setup 38mm rear piston afaik

Come to think of it, the Edition 35 didn't come out until 2011/12, so the 2010 rear calipers couldn't be Ed.35

 

Is there a red rear GTI caliper that came with a larger than 38mm piston in standard guise out there?

[swgti]

Didn't measure the new ones but they seemed visibly bigger compared to the pistons in my 2005 calipers, I'm wondering now if I'm mistaken but the mechanic who fitted them also commented on it because we did wonder for a while if they actually were the correct calipers for a Golf Gti.

Any chance you could chime in here DaveB?

[DaveB@Vagbremtechnic]

Mk6 GTI rear defo 38mm, don't forget the manufacturers make the piston top wider than the piston itself to decrease the area loading.

Just had Richard the MD at brakes Interntional measure it for me

Thanks for the clarification there.   ON a slightly different note, does a 2011 Skoda Octavia VRS have exactly the same front and rear calipers / discs / pads as the MK5/6 GTI?

thanks Dave! glad Im not hallucinating after all! and yes the 2011 VRS has the same brake setup as a MK6 GTI, amongst other things 

[Acidutzul]

Thanks for the tip Dave, it certainly looks tempting and, as I currently have a faulty GTI caliper, I might as well go for the swap. Can you tell me if I must look for a certain rear brake or engine for the donor Caddy, or any rear caliper from the Mk2 will work? It's a 256mm disc brake on the Caddy rear?

Has anyone done the caddy swap as can't get any information, can't obtain a response from DaveB and Jonny refurb guy isn't helping with a price/won;' respond to emails, so looks like this has died it's death... Looks like im gonna have to go S3, cos i want black calipers...

Im in the same boat, I had got everything sorted right up to the point of paying for it, then when I asked how they wanted paid they stopped responding :-( I know they are busy, but if they dont want the business they would be best not advertising.  Just spent the money on a few other bits and will try them again in a month or so.

[E30Dom]

Lol weird way to conduct a business... thats two people looking to purchase...

I also wanted to know if the caddy 2k calipers fitted the standard mk5 gti carriers, or you need the carriers aswell...

[E30Dom]

Just re-read the thread, gti carriers fit, so just order calipers and will fit with new discs and handbrake cables...
