Some of you will know I replaced the rear disks and pads on my 89 900i sometime back and did a heap of fiddling to understand the relationship of the handbrake controls to the way the calipers work.
Now with the weather getting cold the handbrake lever only comes up two or three notches before it's fully tight and I wonder if the handbrakes are incorrectly adjusted? They do work - but I don't think they work enough. I might try loosening off the handbrake adjusters to get the lever to stop at the correct position (around 8 or 9 notches is the specified stop point I think). The car is due for it's pre-rego inspection so will get the handbrakes looked at and the wheel bearings too.
The handbrakes on the pre-88's are a lot easier to work with and adjust from what I can tell having now had experience with both brake configurations, but perhaps there's something with the rear-handbrake setup that I'm missing. 8-)
