I hate for this to be my first post, but I stumbled on this thread while having difficulties installing my rear brake pads. I do however promise to contribute anything that helps my cause back to this thread
I tried changing out my rear brake pads on my 2002 P5 today, but I'm having a tough time figuring out why the new pads don't leave enough room for the the caliper to slide back onto the rotor. Here's are two pictures..
This shot of the rear passenger side caliper shows how the outer pad sits too far out. It doesn't look nearly as flush as the picture on the first page of this how to after the pads were installed.
It's almost as if I need to somehow move the outer part of the caliper (the part the outer pad sits against) further out. I know that it should be completely controlled by the piston/allen key, but it feels like there needs to be some adjustment here. Is that possible?
I really want to get through this without having to slap back the old worn out pads and drive it to the local dealership. So any and all help/suggestions would be greatly appreciated.
And yes, I know, I *really* need to clean it all out. Canadian winters have been unkind to the 'lil p5.

Kansei said:How much do you need to be able to move the outer pad to get the rotor in? are we talking 1mm or like a full centimeter?
Kansei said:you're sure the piston is retracted all the way... and that the rotor is all the way on? There could be some rust/debris on the wheel hub preventing the rotor from going on all the way, though I can't see that causing it to stick out a full centimeter.

I took it into the local shop with the parts I bought, and asked the mechanic to let me know why there just isn't enough space for the rotor to fit after installing the pads even with the piston retracted all the way back. He said that the caliper (both sides) was seized. I mentioned that I had no problems retracting the piston but that there just wasn't enough space even with the caliber removed. He said it was seized so that it couldn't slide back/forth even though the piston would retract. It sounds like (using my previous picture as a reference) he somehow managed to slightly pry apart the parts holding the inner and outer pads?! I didn't think that was possible.
Anyhow, if I get a chance to pull the wheel off this week and really figure out what's going on, I'll try to post again with some *after installation* pics.
