hey, are you referring to the horshoe 'U' shaped clips that fastens to the brake lines?

 

Here is a good discussion of the screws that I think the_gray_mazda6 is talking about:

yes, that's exactly what i am talking about... didn't have time to take my wheel off and take a picture.

They are not essential to reiinstall. They are used by the factory to keep the rotors from falling off on the assembly line untill the wheels/tires are installed. They do however keep the rotor tight onto the hubs when wheel is removed for brake check or rotation so that you do not get dirt or small pebbles trapped between rotor and hub that would cause brake pulsation. Link below to same problem for rear rotors on a 929 in that section.

these bolts unfortunately are a pain in the rear-end. for whatever reason, my buddy easily stripped his bolts while using a big enough screw driver to take them out. might be considering buying a few spare bolts for these rotors incase something like that happens to me and such.

 

Seriously...I've done so many brake jobs it makes my head spin, and I had never seen bolts like that. I wouldn't worry about putting them back in. (I'm definitely not looking forward to doing the brakes on my wife's 6 now.....)

 

yeah, you learn something new everyday...

 

Soak them in "Kroil", the stuff works wonders....You could also heat up the rotor with a torch to break the bolt free (I'm assuming you're either turning them or getting new ones.)

 

left the bolts off my buddies car... since they weren't really necessary to keep. but as for me, i'm gonna take extra car and keep mine just because that's how i am haha.
