I've just did the swap and I can confirm that, having already the GTI brake system, you only need the stripped Caddy calipers. The GTI carriers, brake lines, brake pipes and handbrake mount all fit and must be mounted on the Caddy calipers.

Am very interested in doing this mod !  :drool:
Does this increase in piston diameter not need a bigger master cylinder?
Also can I use the GTI rear brake pads or do these need to be for a caddy?

Bigger master cylinder isn't needed.
The standard rear gti pads will fit without issue.   :smiley:

Mk3, Type 2K 2004-

And mine have sold, sorry...

looking forward to having them fitted. i didn't realise that early A3 2.0Ts don't even have 286mm rears, so i'm jumping straight from whatever puny size i have now to uprated 282mm

Can u use the caddy 2k carriers? I know you say the gti carriers work but I got carriers n calipers off a caddy and would just be easier to paint both calipers/carriers now and just swap them for my calipers/carriers that are on the car.

Thanks

Nope theres nothing on the Caddy that works other than the calipers themselves and as has been pointed out they need a little bit of a fettle to sort out that is......

1. Removal of the long hard black connecting line from the caddy caliper and replace it with the curly S shaped connecting line from your GTI rear caliper
2. Removal of the fixed bracket on the back of the GTI Caliper (Not the movable handbrake "lever") and transplant it onto the Caddy caliper

Theres no need to worry about the Master Cylinder dont forget in essence we're getting S3/R32 rear calipers in terms of piston size and they dont get an MC upgrade.

Just a refresher, Diameter counts for nothing in braking so GTI Rear Radius is 286/2 = 143mm................S3 rear radius 310/2 = 155mm

So a 8% ish rear reduction in radius over an S3 setup for a 7ishKG axle reduction in weight.......

Dont get me wrong if you're going BIG brakes on the front then the S3 upgrade or even bigger is required to maintain balance.

The caddy mod just complements the NQSBBK really well, dynamically works and doesnt cost a fortune and has reasonable renewables.

The later BOSCH calipers of the 2009- DONT work, you can tell the ones you need they just look exactly the same as stock GTI ones they just need some paint.

In fact some already have them and nobody would ever know   :evilgrin:

thanks for the advice Dave

i had a set of these fitted to the back of my A3 about 2 weeks ago. i've been running an NQS for nearly 2 years and aside from the appearance (wish the discs were bigger) i have been very happy with them. there is a tangible difference in brake balance with the caddy rears. where the car used to nosedive under braking before it now feels far more stable. the car does also stop better (tho some of this may be down to the brake fluid change i had done. my old fluid was less than 18 month old however.)

anyway for the price paid i am very happy with this modification

for A3 owners - i drive a 2006 model year car and had the larger 286mm rear brakes. apparently some A3 2.0Ts have the smaller brakes so you need to check first as you'll need new carriers as well.
