guide pins on stock calipers - better ways to secure
Hi Guys,
As you know the stock brake calipers use these 2 flimsy guide pins with a spring loaded plate to hold the pads in place. I've noticed that these tend to get loose (pop out) over time which is concerning. When I swap pads I use a small hammer to tap them back into place, but is there a better way to secure these guide pins in the calipers? Thanks, Steve |

I've never had one come loose from the track either. The spring plate should also keep them locked in place. That's why they have the "thinner" section for the plate to index/catch on in the middle. You can try getting some new pins and seeing if they stay in better.

I've also never had this issue.
Sorry for dumb question, but any chance you've got the retaining clip on backwards? I can't remember off top of my head if it's even possible for things to stay together that way, but I remember the first time I changed my own pads I was initially trying to put it back on the wrong way. I believe it's mainly the tension from this (in the correct position) that keeps the pins from moving, so if not, then would just get some new stock replacement parts. |

well it happened again.. after a track day 2 pins from the passenger caliper popped out.
This is ridiculous.. I'm not sure what's going on but it's definitely a joke of a setup. You think BMW/Brembo could of came up with screw type guide pins instead of tapping stuff in with a hammer. This justs wears out the holes and makes the pins looser every time you changes pads. Another reason to throw the stock brakes in the garbage and go with a proven BBK. |

The work pretty well for me. I have a small plastic hammer to bit the pin and sure it gets in place. make sure the pin is not just positioned but actually gets into the final position by pressing it.

Have you tried new pins and spring clips? The pins are notched so the spring clip should also prevent the pins from sliding out in the event that the spring band on the inner-caliper side isn't fully seated. Maybe you have very worn spring clips. I had no issues with the design at my track day this past weekend.
