I thought it was possible because I had the caliper hanging a bit lower than normal and maybe it opened an air leak

I plan on doing that tomorrow and hopefully I don't find any kinks

Not that it'd ever hurt to bleed the system and pull out any contaminants that might be in the cylinders, but I'm curious as to your claim that one needs to do so every time you change pads. Is there something special about BMW's that's different from all the other marques?


kiwi29: whats your pedal feel like now? Your experiences sounds a LOT like raceyBMW's suggestion. If everything is normal now, that might have been it. If you still have a soft pedal then something's up with the system and it's time to bleed if for no reason but to eliminate that possibility.
I have been taking his advice and it actually helped a lot

This typically happens when you install new pads but not always... It is safer to Bleed and Bed your brakes...
I never opened the reservoir when I depressed the pistons, I figured I should've though, I might need to bleed the brake system again

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.
