left front brake rotates

I just took my bike to a mechanic to have the tires replaced, brake fluid flushed, new chain and brake pads replaced.  When I rode the bike I noticed a slight "clunking" feel at the end of the braking cycle.  It had been a while since I rode the bike so I didn't know if this was a problem or if I was just being paranoid.  Fast forward a few weeks later and I noticed that when I was sitting with the bike upright and turned the handle bars to the far right, something would catch at the bottom of the fairing.  It took me a while but it appears that the mechanic put the reflector on upside down which caused it to in a position further to the rear which resulted in the interference with the fairing when I turned the handlebars.  Anyway, I thought that if he could screw that up then maybe there is something wrong with the brakes.  I tested the front brakes by pushing the bike and activating the front brake lever.  When I did this, I noticed the brake caliper on the left side would rotate slightly with that yolk bar with the hex nut.  Again, I may be paranoid but it would appear that the yolk mechanism is there to allow for some rotation of the brake caliper but I can't be sure.  Any advice?

The left caliper is attached to a small master cylinder that actuates the rear brake, it's part of the LInked Braking System and it's normal for that left caliper to move.  It's basically doing the same thing that the hand or foot brake does, move a piston that moves a piston at a brake caliper.

 

As for the reflector; I don't remember how they're mounted and don't recall them being close enough to the fairing to make contact.  I also can't imagine the mechanic needing to remove it for that work, but if you see it hitting the fairing then it needs to be fixed.

Take the reflectors off.  They're just extra weight and dorky looking.  IMO.

 

Actually, I know they are government mandated equipment, and I remove them as a protest.  Did the same to my bicycle.

IIRC, the right fork reflector is mounts with the same bolt(s?) that holds that mess of valving/lines on the right fork, so I could see it needing to come off and subsequently being installed wrong.

 

Left caliper rotating is as designed, as Superhawk said.
