Yea, you're all right, Germany is a desert in service aspects. I just
read an article on the ADAC (German Automobilist Association) about
that. VW, Mercedes, BMW, and Ford are reducing their garage contract
partners to one third. I really hate that.

But anyway, Winkler offers a four disk brake system which is originally
designed by Oettinger, and both selling it on same price. I may scan
pictures and translate, but someone should host it for some time on
a web server.

The bad thing is, that this brake system seems not to be deliverable.
A VAG employee, who swaped his T3 engine into an Audi 2.8 liter V6,
needed an enhanced brake system to get the TUV approval, and he
decided for the Oettinger 4 brake system. But after several month, he
tried other suppliers too, he gave up because no one was able to
send the ordered parts.

At least he upgraded his front disk brake to Audi RS2, which is similar
to Porsche, but cheaper to get. He machined the front hub and mounted
the RS2 disks on it. He designed a special adapter plate for the
Audi calipers and mounted all together. The rims had to be changed
to 16" (or 17", can remember) diameter.

Another idea is to upgrade to the SA vented disk brakes. This is
presently discussed at the German T3 forum. You will need the
vented disks from SA, the Hub from SA (only for 2WD), and the
calipers from the Syncro. The rims have to be upgraded to 15".
The EV rims could be mounted when using some spacers.

Another fellow likes to use the EV brake system. But as he is right
working on an engine swap, he starts on this spring next year.

Up to now I haven't found a solution to upgrade the rear brake system
to disks. I will try the Audi 5000, but as it too cold right now, this
project
will be continued next summer.
