I am doing a brake job this weekend. Some vehicles have pistons that just push back in... while others need to be spun back in. <p>Anyone know how to retract the pistons on the XC90?<p>

It's just straight pressure.. not a turn like VW's.<p>I use a large C-clamp.<p>Good luck.

<p>Use a soft brush to clean them well before pushing the back.. The seals will thank you.

I agree with the large C-Clamp. I posted a "how-To" on the front brakes a back a while, here is the link. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> <p><A HREF="http://home.comcast.net/~toddhaddon/Volvoxc90.htm" TARGET="_blank">http://home.comcast.net/~toddhaddon/Volvoxc90.htm</A>

Thanks guys! <p>I had to buy a tool for a VW brake job a couple years ago when I owned a Passat just to spin them back. I did brakes on my '00 V70, but I had forgotten how they retracted.<p>Good idea about keeping the seals clean.<p>Thanks again.

As a further suggestion - you may want to open the caliper bleeder screw and dump the excess brake fluid out rather than pushing it back up the lines when you are compressing the pistons. <p>You are getting rid of the more 'used' fluid this way, and is a good first step towards the bleeding/flushing the calipers.<p>By the way, check out the Motive Products Brake Bleeder- iPD carries them, as well a lot of other places. It makes brake bleeding/flushing a one man job.<p>Good luck.

Hardly ready for replacement.<p>The brake job was easy, I could almost push the calipers back into the rotors with my hands! In fact, to get the caliper apart, it was easiest to rock it back and forth and force the piston back in place. Kinda cool how the brake line is long enough that I could flip the caliper over and place it on the rotor - I hate having to "hang" some on wire while you work.<p>The most difficult part was figuring out how the spring/clip is held in place. Interestingly enough, the pad itself has a bracket which holds it.<p>I really only needed a couple tools to do the whole job:<p>7mm hex<br>C-Clamp<br>Flat screwdriver<p><IMG SRC="http://www.schnellauto.com/images/Brake_Job.jpg" BORDER="0"><p>

<B>Where were you able to place your jack stands? It looks like your jack would block the easiest jack stand location...</B><p><br><IMG SRC="http://home.comcast.net/~toddhaddon/Beforesideview.jpg" BORDER="0"><p><br><B><A HREF="http://home.comcast.net/~toddhaddon/Volvoxc90.htm" TARGET="_blank">http://home.comcast.net/~toddhaddon/Volvoxc90.htm</A></B>
