I would expect the disc to be hot and was surprised the the left disc was completely cold, leading me to believe the caliper was not working on that side.

as the wheels are free my first suggestion of a blocked brake hose 
wouldnt apply.
The front bolt on the torque tube is a very good place to start for the 
thumping ,also check the mount itself as it can break down.

the left calliper does sound like the adjuster mechanism.
it has either frozen or more likely when the callipers were put back,the 
pin has dropped into the actuation leaver's grove. this can happen when 
you are putting the calliper back in the car.when putting put the big 
hex nut on the end of the calliper pivot pin usually the end stop screw 
is removed and the handbrake actuation leaver is rotated the allow a 
socket to tighten it up.Unfortunately if the actuation leaver comes out 
more that a half inch ,the internal pin that operates the brake 
mechanism drops sideways into the grove on the leavers shaft and there 
is no other way to fix it but pull the calliper appart.
I know mutter mutter
to confirm this has happened see how far the leaver rotates when the 
hand brake has been applied compared to the RH side
I hope this makes sense
