I just changed out the non-functioning hydraulic brake light switch on the master cylinder on #804.  The new switch solved the problem of no brake lights .  This subject has been covered several times in this forum including a "factory" bulletin on how to replace the switch.  While I was under the car I did an inspection of other components of the brake system that is covered by the aluminum box protecting the master cylinders.  I found some play in the adjustment rods as shown in the video link below.  Just want to verify that this is not something I should be concerned with.  Thanks in advance.
