An adendum to the 320i Rear Drums Upgrade FAQ

[Mike87]

There is one issue that may have been overlooked in the FAQ on updating to 320i 250mm rear drum brakes. That issue is the parking brake cables.

In the FAQ, the cable is mentioned, but assumed to be stretched and therefore not a potential problem. My car is a ’72 with original cables. They have not stretched and when I went to hook up the cables, they were too short by about an inch. My solution, with the help from the FAQ community, was to replace the cables with cables from a turbo. The P/N is 34-41-1-110-971. For reference, the part number of the stock cable is 34-41-1-103-128. The new cables fit perfectly and were just long enough.

There is another method to fix the problem. First you remove the original cables completely from the car. Measure and mark the tubes that are welded to the body where the cables enter, 12mm (about ½”). Cut these tubes and leave the end square so the cable will fit flush. Reinstall the original cables and adjust.

You may not run into this problem, but you should be aware of it prior to doing the job. This will allow you time to choose a solution should it arise.

Thanks for your time,

Mike
