I need a set screw and the bmw oem set screw does not fit. Does anyone know if Zimmerman uses a different set screw? Parts store could only come up with the bmw # that doesn't fit. Thanks, Eric | | | 07-28-2013, 03:15 AM | #2 | Senior Member Join Date: May 2010 Location: Montreal Posts: 283 | We just refreshed my 97s stock brakes, front screw was the same as the rears but the dealer wasnt listed for this for some reason. I think he was mentioning that the e46 was different somehow. Try realoem and compare | | | 07-28-2013, 07:44 AM | #3 | Senior Member Join Date: Feb 2007 Location: Fl Posts: 1,353 | The 300mm rotor takes the same set screw that the ti does. There should be absolutely no issue. Post up some pictures. __________________ SUPPORT 318ti.org! CLICK THE LINK ABOVE!

I had looked all over realoem and all the e36/e46 were showing the same part number, which is in one of the attached photos. Did you (mtblue) end up with a different set screw than the one in the photo? I attached a pic of the rotor too, I don't know if it will help. The set screw is roughly 4 threads too long. So, the original issue was a scraping/grinding coming from the brake when slowing down from ~10mph and under. The pads have ~20k mi on them. I checked out the pads and they're in good shape; the only thing amiss I noticed was the set screw was missing. | | | 07-29-2013, 05:20 PM | #5 | Senior Member Join Date: Feb 2007 Location: Fl Posts: 1,353 | Quote: Originally Posted by mreroc Thanks for the input and help guys.

Not sure if this is obvious (if so, I apologize in advance) but in the picture of the rotor, the rotor is not aligned with the hole for the set screw. Turn the rotor until you see the hole in the rotor line up with the hole in the hub. Additionally, a missing set screw will not cause any issues at all when the car is going down the road with all the wheels tight. __________________ SUPPORT 318ti.org! CLICK THE LINK ABOVE!

There is no hole to align with; I checked thoroughly. My rough theory was it split off and part of it fused to the metal, the other part and shavings gave me the grinding? However, I cannot see any sign of it fusing, unless it did so that cleanly. Is this even a possibility? | | | 07-29-2013, 05:53 PM | #7 | Senior Member Join Date: Feb 2007 Location: Fl Posts: 1,353 | Quote: Originally Posted by mreroc Right, I forgot that relatively important part.

Pull the rotor and snap a picture of the hub surface. As for the grinding/scraping, check all the dust shields and make sure they are not contacting the rotors. __________________ SUPPORT 318ti.org!

I'll look at it again tomorrow. | | | 07-29-2013, 06:24 PM | #9 | Senior Member Join Date: May 2010 Location: Montreal Posts: 283 | Same screws that i have, but you have something else going on there.. but you say nowhere for you to screw yours into the hub? That can't be. Turn your disk till it aligns, it has to go in.. not sure if that's the root of your scraping though, caliper touching the disk, are you using the proper carrier, pads? That's all i got lol | | | 07-29-2013, 06:38 PM | #10 | Senior Member Join Date: Aug 2011 Location: Phx Posts: 196 | Thanks. Yeah, everything is right. It was a long weekend trying to decipher this. Back on it later. | | | 08-02-2013, 01:59 AM | #11 | Senior Member Join Date: Aug 2011 Location: Phx Posts: 196 | Just to bring an end to this one. Despite the odds, the set screw did shear off and with the heat made a real clean seal, thus the difficulty and confusion. Just leaving it in there. Thanks for the help. | | | 08-02-2013, 02:32 AM | #12 | Senior Member Join Date: Feb 2007 Location: Fl Posts: 1,353 | When you need a new front wheel bearing you can fix that issue. __________________ SUPPORT 318ti.org!
