Thanks Nate,
I thought so, but maybe his has a different setup. Is this a USA Jetta?

So do you think that his "new" parts are defective then?
If the caliper frees up then I will assume that the caliper is not the
issue. It could be the brake master cylinder or the brake hose.
Next check would be to open that caliper's line at the master to see if that
frees it up too. If it does then master, if not then hose. I doubt if the
line could be causing the issue unless it is crimped somewhere.

Oh I better ask the OP......... How do you release the pressure on the right
front disk?
Lets hope that the slides the brake pads ride on are not too rusty and the
pads can easily slide.
