Hi Goran,

Here is the thread (http://as8.ru/forum/viewtopic.php?f=84&t=18998 -- it's in russian, but use google translate) on installing 310mm rear discs from armoured A8 with some pictures. The guy didn't want the hassle of RS4 install, so went this path with a couple of others. He had to use custom made bolts though, so it's not 100% OEM install.

I personally think normal A8 rear callipers and pads look a bit 'sick' on such a large 310mm disc since not the full surface of the disc is utilised. I think it was Audi's 'makeshift' solution for an armoured vehicle. I DO LOVE thought the brake pad wear sensors part of the story .

Today I managed to retrofit the rear pads wear indicator harness to my D2. It is relatively easy to do if you have a whole day.

The new retrofit harness is inserted into existing harness without having to cut any cables. All you need to do is to trace wire from the front wear indicator that merges with the ABS sensor wiring in a front wheel arch into a single 4 wire harness and then connects to the main car wiring via a 4 pin connector. All you do is disconnect that connector into parts A and B and then connect part A into part A of the harness and then part B into part B of the harness (see the first picture below with Y type of wiring with two connectors).

The connectors can be found of both sides of the car so you will have a choice to run the wiring via the left or via the right side. I have chosen the right side as I had a spare slot in the clamps which hold the 3 fuel lines which run from the nose to the rear. The unused 4th slot was used for wiring. I also changed metal part of the clamps since they were too rusty on my car. They cost pennies.

Pictures!

The front side of the 'plug-and-play' connector


which can of course be looped


The full harness, about 5m. Just the right size.


Rear wheel 1 connector


Rear wheel 2 connector


Old fuel lines clamp. Notice a spare slot from the left hand side of the picture


Rusty clamps changed and the wiring fitted now (corrugated plastic pipe on the right)


Connect the new harness to the rear pads wear indicator connector


And hide the connector in the recess of the wheel arch
