Good comments. Here is my two cents.

Or purchase one of these for $8.75 from a E46Fanatics sponsor: Caliper Compressor

Parts are real dirty. Ensure you have a large drop cloth or cardboard under the wheel before you work, preferably something you can throw away, to save your garage floor from getting real dirty.

I just replaced my front rotors and pads. A pretty easy DIY when all goes as planned but like most things on an 11 year old car, nothing goes as planned. One rotor and pads went as smooth as could be and was done in 30 minutes. However, the rotor bolt on the other side was a b!#ch!! The head was slightly stripped before I started so I hit it with some Liquid Wrench to help it a bit even though I don't think that really helps due to the shape of the bolt. On my first attempt to remove it, I stripped out the head even more. Terrific!! I tried every trick I could find on the web. I reshaped the hole with a larger torx bit and tried removing the bolt with that. No luck. Whacked it with a hammer to tried to break it free from the rust. Still no luck. I tried using a screw extractor but that only made the condition of the head worse. I cut a slit with my Dremel and tried a screwdriver (torquing it with a wrench). Nothing. I tried an impact screwdriver to help break it free and again, nothing. I then tried the blow torch method, hoping the expansion and contraction from heating and cooling would help break it free. Again, no luck. So I finally resorted to drilling out the top portion of the bolt so I could at lease remove the rotor. Finally, success!!

At this point, I was so tired of dealing with it, I left the old bolt in place and used it as a guide for the new rotor. At some point, I'll remove and replace the old bolt but I'll fight that battle another day.

Anyone have the part number for the rear sensor? You'd think being in Germany they would sell me the right parts to a German spec 3 series, but they sold me two of the wrong rotors for the rear and both sensors had short wiring so it only fit on the front. The rear couldn't reach.

34351164372 is the rear sensor I have. This was ordered from AutohausAZ. http://www.autohausaz.com/search/pro...0Wear%20Sensor

Sorry, mine was for 2002. According to AutohausAZ for a 1999 328iC you need 34351181342 and gives a length of 790mm. Hope this helps.

I think I need the one that is 1410mm it's a rather far distance to the box from the rotor where the elbow clips in. The ones they sold me here in Deutschland didn't even have the rubber clips around the wire to secure it to the frame.
