Need to replace the rear discs on my 2010 quattro. I have replaced discs before on this generation so know about using Ross Tech for the electric parking brake.
I've had a quick look and the lower bolt to remove the carrier looks very restricted on the quattro.
I' guessing audi use a specialized tool for this bolt

Any tips on this hugely appreciated
Thanks.
 
When I did the discs on my S4 I found access to all the securing bolts a little awkward but managed to get it done without any swearing or grazed knuckles.

I did the work off axle stands using a draper socket set so sure you'll be fine once you get into it.

Thanks mate. That lower bolt just looked too awkwardly close to rear axle. I guess you have some nice thin walled sockets?
 
No problem getting to bolts, with a standard 1/2" wrench set. No need for any special sockets or any other accessories. If you are a little weak, you may need to loosen the bolt with a small sledgehammer on your wrench.

And you don't need Ross-Tech for the handbrake. Carista has the function as well, but you can also just remove the motor and rewind it by hand.
 
Or you can lift the rear of the car, turn the ignition on and release the handbrake as usual.

Couldn't get carista to work so had to improvise.
 
That doesn't help to rewind the handbrake, so you get new pads on, and if you change discs, then you should definitely change the pads at the same time.

I thought the VCDS/Carista handbrake function just releases the handbrake, it doesn't wind the piston in ? I've always used VCDS then pushed the piston back with a G clamp just enough for the new pads.
 
Don't know what you are talking about. I'm talking about the electrical handbrake.
 
So am I. The VCDS function is the same as pressing the button inside.
I've always had to push the piston back once the handbrake has been released with VCDS.
That was with an 09 A4 - the A3 has an "old fashioned" handbrake and my A6 looks similar to the A4.
 
You must be doing it wrong with VCDS. When I have changed the pads / discs on my B8 A4 VCDS winds the pads back all the way. This means you can fit new pads and discs with no issues. You can't force the piston back as this will damage the handbrake mechanism.
When the new pads/ discs are installed VCDS then actuates the motor to close the caliper up.
 
Desertstorm, I thought, as well as fully retracting the mechanism electrically used VCDS, when fitting new discs and pads, you should also mechanically wind back the end of the piston using a suitable adaptor and the normal piston rewind tool? I have had the pads out to clean things up and used VCDS for that, but I've also bought the VW Group electric handbrake rewind adaptor for my rewind tool, though never used it, though I'm sure that I did check that it fitted the end of the pistons when I took the pads out to clean the callipers up a bit.

I've replaced pads on the electronic handbrake a few times and I've always had to push the piston back. All the VCDS function does it release the motor allowing you to push back - if you don't release it, that's when stuff gets broken: http://wiki.ross-tech.com/wiki/index.php/Working_on_the_Electro-Mechanical_Parking_Brake_(EPB)

Ross-tech say you need to push the piston back as well. Perhaps there is more than one variant ? Wouldn't surprise me!
