Hi all, I havn't seen any info. detailingwhat's necessary to remove 321mm front rotors. Most posts refer to the AudiWorld Tech Articles that only describe pad replacement. I tried this morning to pull the rotors and didn't because the brake bleeder nut is in-line with the upper caliper fastener. It must be removed to provide access to the caliper fastener. Since I didn't have any brake fluid for this system I had to stop. Has anyone done a rotor replacement, themselves,and encountered this issue? Is the solution to remove the bleeder nut and let the brake caliper/line depressurize before the caliper fastener is removed?
Seems like a poor choice to locate the bleeder nut in-line with the fasterner but perhaps there is a good reason. ANY relevant help would be appreciated.

 

...should have mentioned it's an HP2 brake system. Thanks.

 

WHen I did my brakes, the bleeder did not have to be removed to remove the caliper. There are 2 screws under the 2 rubber covers, remove the covers & remove the caliper, or remove the carrier bracket.

 

2K is right. I have a 2K 2.7 and I did my front and rear brakes, pads and rotors. Take pads out like the pic shows. There are 2 18mm bolts on the back of the calipers. You have to use a little muscle to get them loose. When you do, you can lift the calipers off. Use something to hang the calipers up with. Don't just let them hang by the hoses. Then I took a hammer and tapped the rotors on the side and top until they came loose. Good Luck.

 

make sure you use med grade lock-tite on the 2 bolts for the caliper bracket if not they can come loose (it happened to me not fun)...

 

I am working on the same thing. i am having a hell of a time removing the 18mm bolts...Any tips or tricks would be greatly appreciated... I am considering air tools, but will i be able to get them in there?
