Can someone confirm this is the correct OE fluid?

Stuck rear guide pins
Reviving this as I am stuck similar to the poster in post #98.
I can’t for the life of me push any of the rear guide pins. I’ve used wd40, soaked for few hours and the pins don’t budge. The worn pads move freely, the pins are not seized on the metal bracket. I wonder if the guide pins are seized on either caliper surface. Appreciate any pointers/help? PS: for some reason the rear guide pins seems to stick out more than the fronts. PPS: there’s great set of videos for the front and rear brake/disc job Last edited by aboulfad; 05-29-2023 at 07:43 AM.. |

To remove the front pins, are you using an appropriately sized punch tool and hammer? If the punch tip is too thin you won't be able to direct sufficient force on the pin. Those calipers look brand new btw. I imagine your tip toeing to keep them chip free. Try sending it. |

It just doesn’t make sense, the pins on the front caliper went out normal, no fuss : |

Tried multiple rust “penetrating” sprays over multiple days, the rear pins don’t want to budge on either side.
The TA mentioned the guide pins require frequent cleanup else they’ll seize especially up north & winter driving,… have an appointment this week, sucks royally as they charge almost the labour for front/rear by doing one axle. |

If I were local I would love the opportunity to give that pin a good thwack with my punch tool and hammer. See if BMW allows you to observe the service tech removing it. Maybe ask for a video. I just can't imagine how it's siezed.

If mechanical force can’t dislodge it, then it’s heat, spray, hit… I am sure that’s what the mechanic will do. Unless by that time the penetrating oil does it’s magic & they pop out PS: my theory seems to be correct, our friends at MB also have the same issue with these guide pins.

Success!
Ok maybe the penetrating oil has been doing it’s stuff for weeks... I went to a corner mechanic who’s an acquaintance. He was able to punch them out maybe it’s the little trick where he pushed back on the expansion spring w a screwdriver and hammered out the darn pins! No heat or cutting
They were indeed seized/corroded at both ends, check the pics. So much stuff lodged between the collar and pin and some paint was stuck on the collar! Nice shiny brakes & rotors all around |

Given it’s a RWD, maybe more guck gets lodged there with wheel spin. The dealer recommended cleaning them every few years. |
