The orange (o) symbol light up with a short beep everytime I started the car... I guess it is time to replace the front pads...right? Do I need some special tool to do the job (DIY)? I have experiences with Japanese cars before but haven't try an Audi yet! Thanks for you input...

No special tools, but a $2 C clamp or something similar is good to have to compress the piston. I would also pick up a package of the dark green lube to put on the slider bolts. I forgot the size of the allen wrench you need for those. If you are changing the rotors, I think the carriers are held on by a 17mm. You may need a breaker to get those off if they've been on for a long time.

after removing the wheel there are 2 bolts holding the caliper (sorry, can't remember the size). I used some loosening stuff and a breaker bar.

I used the reset tool for the piston but like Shameless in Chicago mentioned, you could probably use a C-clamp. I know I shouldn't press on the pad directly but I was pressed for time.

I hope this helps.

autoparts store and either buy or rent the caliper tool. To buy its about 30 bucks, i think where i bought mine, you pay for it full price and they give you a full refun if you bring it back in a certain amount of time.

C clamp works just fine on the front. Hell, I've used old pads and a hammer stuck between to do it.

Only need caliper tool for rear change

you could have just loosened the slide pin and kept carrier on

the pics were taken on my wheel bearing job so I had to remove the whole thing.

Like SiC said, calipers are calipers.
