Default caliper slider pin?

So... I haven't posted in a while. Because the ti isn't doing so hot. I'm in a really tight spot financially and my car has only now been on the "able to spend money on" list. My brake caliper rests on the inside of my wheel now. I got a huge bang on my street right before my driveway (lucky me), and my brakes went out. Visual diagnosis spotted the rogue caliper, so I removed the wheel to investigate. The caliper seemed to be in the right place with the wheel off, so I put the wheel back on, and the caliper wasn't rubbing then either, so I pushed the car forward in my driveway, when the caliper began to rub again. I have checked to make sure it wasn't just one part of the rim that was touching, it stays there consistently. I asked a mechanic bud and he said it sounded like a broken caliper slider pin. I've never even heard of these, and if that is the case, what might I be looking at to have it fixed. I don't want to get ripped off by a mechanic. Thanks for all the help guys

i don't know what the slider pin is but there are the two guide bolts that go into those rubber holes in the caliper itself. there's the anti-rattle clip on the front of it and then there are the two bolts that hold the carrier down. those are the only things I can think of that hold the caliper in place

Is it the caliper or dust shield scraping?

is the caliper pivoting? not making sense that when you put the wheel back on it wasn't rubbing and then it started to. btw, here's a link to the front caliper diagram on realoem that might help: http://www.realoem.com/bmw/showparts...69&hg=34&fg=05

You can have a seized caliper guide pin.

I had the exact same problem now that I think about when I went to solid guide pin bushings. I removed them and went back to stock since then.

You may want to try getting a bushing replacement kit with new guide pins.
Do both sides.

http://www.realoem.com/bmw/showparts...69&hg=34&fg=05

34111157038 KIT GUIDE BUSH MSRP $14.60
34111157041 GUIDING BOLT MSRP $20.10

A good price would be 20% off MSRP.

It get can all gummed up. In my case it was the metal bushing that caused the binding.

I just can't think of anything else.
A caliper is a pretty simple device.
