There are special tools that will push the piston back and rotate it at
the same time. Get one for ca. USD 20; it's a good investment. I've
replaced my rear pads twice using this.
But I don't know what the procedure is to change the rotors/disks.
If the rears are like a '98 v6 A4 quattro, they are pretty easy to do if you
have the tool that compresses and turns. When I did it a couple of years
back, AutoZone lent me the tool for free (refundable deposit). I did the
rotors too and they were quite straight forward.
Naturally, an Audi (or any other car) of MY 2000 will have ABS.
A good point about potential damage you bring up. Some have claimed that
pushing/rotating the piston back in may, in the event of contaminated
brake fluid in the pistons, push the contaminants back up into the ABS
mechanism, rendering it less effective. Others say that it makes no
If you are worried about this kind of thing (or if you don't flush your
hydraulics with new fluid every two years), then an accepted way around
this is to loosen slightly the brake fluid nipple on the (rear) brake
being worked on, so that the fluid being expelled from the chamber goes
out the nipple, not back up the system, when rotating the pistons back
into the housing. Of course, use plastic tubing to lead the fluid from
the nipple to a bottle. Remember to tighten nipple once job is
completed. Repeat for the other brake. Top up brake fluid reservoir with
new fluid if needed.
I do the above procedure myself and am pleased with the results.
Thanks for all the help. I called autozone and they have both tools
that can be used for the brakes. I think I will take the tube
suggestion. I believe the bottle should have fluid in it as not to
allow air into the brake system.
So thanks to you help I'm going to save about 500.00 by doing this
myself and not taking it to the dealer for something that will take me
a couple of hours at the most.
