I finally gathered all the parts to do A8/TT brake upgrade and got around to install them today.Took me only a couple of hours to install everything, and I took a few pictures in process for those who might be interested.

Old G60 brakes.

Old rotor, caliper, hose bracket and dust shield removed.

New A8 brake rotor, A4 brake caliper and TT carrier bolted on. Calipers and carriers have been cleaned up with the paint stripper,sandblasted and painted with G2 caliper paint before the installation. I decided to use Axxis ultimate pads from late A4/Passat, p/n 109.08400, since I want to retain a brake pad wear indicator. I am planning to replace the connector on the wiring harness with the one from new A4 (p/n 893 971 992), but haven't done it yet.

I used OEM VW/AUDI male/female 335 mm brake hose p/n 171611701L, used on regular 4000 and 5000. It might be just a little bit too short, but fits much better than original brake hose (405 mm), which is way too long to use with A4 calipers. I still have not decided whether I should make a new bracket to support the hose in the middle or leave it as it is.

Installation complete. Plenty of clearance with 16" OEM Tango wheels.

Finally, the price breakdown:

New A8 brake rotors (ATE) = $90x2=$180 (European Automotive)
New TT brake carriers =$121x2=$242 (European Automotive)
Used Audi A4 brake calipers from 2000 A4 with 20K miles = $100 pair
New Axxis Ultimate brake pads =$76 (Stoptech)
New carrier bolts N 901 740 01 4x$3=$12 (dealer)

Update: I ended up changing the brake lines to a4
setup - they seem to fit better. I bought short metal brake lines (8D0 611 721F/722F),brake hoses
(8d0611707B) and brackets (4B0 615 13B/134B).The only modification required is to cut a small slots in the brake hose bracket on the car to fit a4 brake hose.

And I'd recommend securing those brake hoses.
Leaving them to dangle in the wind, will allow undue flex stress to where the hose crimps to the the fittings.

Noticable improvement?

Well, I've only driven a few miles so far, so the pads aren't bedded in yet. Today it was raining, and there are not too many places to do a 10 60-5 stops in DC metro area on Saturday afternoon to bed the pads in properly, so I am taking it easy I'll post an update on how they feel in a few days.

would this work on a 88' 5ktq?

Yes

So, no custom machining or funky brackets (a la BIRA) required? Hot damn! =)

Nope, all OEM VW/Audi parts

anderssj

are the TT and A4 calipers the same? Are they ATE 57 type?

Thanks!
