I did a couple of things:
1.My LBs found a bolt(?) that would go on the end of the barrel adjuster. It works but not as well as the OEM.
2. As a backup, I found 2 of the Magura brake levers online at a bike shop so I purchased them in the event I have the problem again.
3. I bought a set of HED Ardennes wheels to replace my Mavic Ksyrium training wheels so now my race wheels and training wheels are the same size and should not need to adjust the brake width as much has the previous 5 years.
Best of luck.
