This is the six piston Brembo caliper on my 135i. Was under to do the brake fluid flush per the schedule, and noticed that there was some dampness around the threads, and the powder coat paint is slightly damaged.
Did the bleed, and noted that while the bleeder screw would get tight, it felt like I could always give it the same torque another time, and it would turn another partial (like talking a degree or three). My concern is that these are likely aluminum calipers, and so it is highly possible that they are soft.
The car hasn’t lost enough fluid in the last two years to be noticeable in the reservoir. You can see the rest of the body is dry. But I’m concerned that once this starts, the threads just keep failing (and that’s assuming the threads are somehow damaged, I don’t know that absolutely).
Any experience with bad bleeder screw threads? Any recommendations for how to proceed?
