replacing front rotors (HP2 calipers). do i remove 2x 21mm bolts or the 7mm ones?
searching the archives. the A4 tech article shows removing the plastic caps to access the 7mm bolts to remove the caliper. something tells me that's not right for the A6/ar (now that I look again, the bolts under the plastic caps don't have a hex, int or ext, on them). However, i can't get those 21mm bolts to budge. I only want to get the rotors off, not replace the caliper. help, please.
messy job, by the way, geez |
You need to remove at least 1 of the 21mm bolts.
if you can't get both, you can generally swivel the caliper on the stuck bolt. " very hard to remove" is very typical

You're not kidding they're tight!
My upper body ached for days after doing the HP2 swap. (no air tools, and I'm a skinny guy :)

I separated a rib!

well I gave up. w/o a lift I can't get enough travel with a breaker bar to loosen them.
Guess I'm paying an installer. Grrrrr.
|
Did you try turning the wheel completely one way or the other? Might give you enough travel.
|
I may try again tomorrow. too pissed off now. :)
|
rare that you can't phase the socket on the breaker....
to get the right position to crank on the bolts. What I'm saying is that if your socket isn't providing enough travel, take the socket off the breaker and rotate 90. Common issue.
|
Where are you located? Perhaps someone can lend a hand, finger or rib.

You need a ton of leverage
Get the biggest ratchet you have and hit the end of it with a mallet. They come loose. Just grease them before you reinstall. I did mine a few weeks ago.
