It will work on a 2WD Vanagon as long as you can get ahold of a pair of South African front hubs. They resemble the Syncro hubs, but are of course free wheeling hubs with conventional bearings. It is possible to get a machinist to machine down the center section of a standard 2WD rotor into a seperate hub. However, it is hard to find a machinist who will do this from what I've heard.

Oops - you are absolutely correct.

It won't due to 1 pc front hub/rotor on 2wd Vanagons.

That is my opinion exactly - the metal is all strong enough, just needs to be tight, and this "stays" better than a nut on the end IN MY OPINION (as in I don't want to argue)

Quote: By the way this whole set up you desribed is being sold on e-bay by someone regularly, starting bid is 500$, with a buy it now of 550$. All work ,mods done , just bolt it on.

That was me - there was no interest shown, and, at $500, it just didn't pay for the time involved

I guess I should have been more clear about what I meant. When I said "thread strength", I meant the threads in the caliper carrier not being strong enough to allow the the bolt to be torqued (strecthed) enough to keep the bolt tight without failure (or at least radical distortion of the threads).

If your comfortable with it, cool!

TT carrier 8N0-615-125, A8 disc 312mm 8D0-615-301J. I got this from an Audi site as an upgrate to 5000. Therefore the same mod to the carrier should put this massive rotor on a syncro,if you can fit it in the rim, my 303mm just fits my 16" rim.

Mike,
Nice work.
One question, were the hangers included with the calipers when you purchased them or did you have to find them on your own.

Carriers were included. I purchased allparts from www.rockauto.com, parts are here next day, and the prices are really good.

I will be starting my rear brake conversion to Disk. There is another really good thread on this now, I just can't get myself to use spacers in the rotors.

Mike,

What wheels are you using with your Audi big brake upgrade?

Just finished having my Small car aftermarket brakes professionally installed and they look great. and they should soon provide excellent stopping power. Problem is, that my engage point on my brake pedal has dropped considerably. It feels that I almost have my foot to the floorboard before I feel the brakes grab. I couple quick pumps of the pedal and it feels more like normal but as soon as I got to brake again it the same issue. Are my larger calipers needing more fluid to go through the system thereby makeing me press further to move more fluid? Were my new brakes possibly not bled well enough? Might this issue go away as the system builds up more pressure? Imput please.

The pros didn't bleed your brakes correctly and there is still have air in the system. The pumping up the pedal is a dead give away of air.
