Hi there,

Yeah you need vagcom or a similar to wind in the piston. Have a look at the Ross tech site as there's a video of the process. They really stress the battery charger thing too, so I'd be safe rather than sorry there. I believe I put the brake on, then off again, then wound it back in with vagcom. Then simply compress to get the visible piston back in.... You hear winding noises but nothing visible when winding in with vagcom!

Was pretty easy and quick to do!

Just did this on the my 2005 PF D3. Went surpirsingly well!

You need VCDS or similar to wind in the parking brake (hook up battery charger, follow Ross Tech Wiki/youtube vid). I initially struggled with it, as the caliper wouldn't compress back in, so put old pads/disc back on and re-did and bingo!

Used a big G clamp to compress caliper. The Star screw holding the disc on was a bit of a sod, but means the holes all align when putting the wheel back on so actually makes it easier.

Lift on the MMI and then Jacking mode and theres even a slot for a trolly jack on the D3 and it's high enough you don't need to mess with the Audi Jack

Actually a lot easier than on my old D2 with the rotatry brake tool.

Pair of black EBC slotted discs and red stuff pads and the braking is good, quite, smooth and efficient. £190ish all in +++

One pair was utterly dead, just starting on the rivets, the others low but ok. discs old. Am guessing that it had been previously done without VCDS as i got no dash warning until after changing!! Pads entered in as 10mm (they measured close to 11, but were under and am guessing a high value gives a late warning!)

have you got the details (part numbers of the Pads) mine are in need of replacing and struggling to make sure the fitment is the same.

cheers

I put these on mine.

The slotted discs and red stuff pads seem to work well for me :D

Thanks OP for the post - most useful.

I've been researching the heck out of this subject in a bid to do mine sometime soon.

I noticed that the diameter on yours is 310mm whereas on my 3.0 TDI (D3) the rear discs measure to be 280mm. So I ordered some Brembo ones from Amazon (didn't even know they sold brake discs!), I already have the pads from when I purchased the front and back pads, again Brembo ones.

Here's the link for the Discs:

Brembo Rear Discs

On a side note, around 3 years ago one of my rear calipers would not unbind off the disc, and it was diagnosed to be a bad caliper.. the car ended up at a German specialists and they proceeded to sting me with a £600ish bill for the replacement caliper + labour costs.

Upon collecting the car, I was informed there had been a mistake within the invoice, and there had in fact been another part which had 'gone' and thus had to be replaced, taking the total invoice to around £1200..

Having watched the Ross Tech video, and particularly paying attention to the part where it is stated that on some A8's if you don't wait the 30 seconds or so after the calibration, it could fry your EPB module, i'm now starting to wonder..
