    check the information forum index thread nice write up with pictures, on my 99 rears you have to use a caliper retraction tool that turns the piston as it pushes it back, you cant just push it in like the fronts. harbor frieght sell this for under $20 when on sale otherwise its $30, you can rent the tool from some auto stores others will tell you more.

    oh yeah you might as well flush the brakes so brake fluid and a piece of tubeing or a cheap little brake bleeder kit around $5 from harbor frieght.
    on my passat brake flush new pads and rotors is a pretty easy job, just follow the write up.

    Bentley manual says that rear caliper bolts are one-time use and must be replaced.

    I just got that piston push back tool from HF last week. Quality was better than expected by HF standards. And, it also will work on the front brakes which don't want the pistons to spin as you push them back.
    Here's the link:

    Still on sale.

    Ok...I just did the same thing on my 03 4 days ago so I wanted to chime in. Granted I have done brakes before but I am an amateur when it comes to rears on a Passat. I did however manage to get the job done and they work great.

    After the wheel is off you will have to take out 4 bolts. 2 of the bolts you will need an allen wrench, these bolts are behind the rotor. The other 2 I used a socket wrench (for space reasons the socket only worked on one of them) and a open ended wrench even though a box ended wrench would work as well. You will notice the the caliper bolts will keep turning when you try to loosen them so you will need another wrench to hold everything steady. With a little nudge hear and there the caliper should come off and then the other part (held on my allen bolts) should follow. I recommend only loosening the allen bolts, then remove the caliper bolts, then the caliper, and then completely remove the allen bolts. I found out there there is less to get in the way this way. Then secure the caliper with a hanger or something so you don't damage the brake fluid line. At this point you may have taken off the old pads or you can wait. Bang the rotor in a few places to break it free. I used a hammer since that was all I had and it worked fine. After all you are putting new rotors on anyway. My one rotor came right off after a few bangs and the other one took 15 minutes. However it will come off at some point. After cleaning up the area or anything else you might be doing put the new rotor on. I used 2 lug bolts and hand tightened them to hold the rotor in place during the break installation. After cleaning up the caliper and what ever else you have to do you will want to retract the cylinder (ALL THE WAY). I actually rented the tool believe it or not for free from a local Auto Zone but you should buy one if you have the room and you have time for the shipping since it is so cheap on line. I am assuming that our cylinders are the same so in my retracting tool kit there were 2 discs/plates the fit the diameter of my cylinder and I actually liked the one with the shorter nubs on it. I actually got used the disc with the longer nubs and got it jammed in my caliper when trying to retract the cylinder. The tool is pretty easy to used I was just a little over worked and retarded the day that I did my brakes. After the cylinder in retracted all the way start putting the brakes back together. The rest is pretty easy and just remember what you did when you took them apart. After the brakes are back together the lugs can come out and the rotor will stay in place until you get the wheel back on.

    Good luck to you. I wanted to help out a little since so many people have helped me.

    Even my dealer didn't have these bolts in stock, so I don't think they are commonly (ever) replaced. I ordered some from ECS, who also didn't have them in stock, and the ones supplied didn't look like the originals, so I used the originals.

    I had a VW shop foreman tell me to just clean them (a little very light sanding if necessary) and wipe on the thinnest imaginable layer of high temp brake part grease on the shafts. Of course I didn't bother becuase they looked fine.

    If it's really an allen wrench socket head cap screw, then you might need a size with a .5 mm instead of the even mm sizes. Someone on here will know. It might also be something else like torx.
