Congrats on your success.  I think I've got you beat with my TR3 project, 
however.  But it's been so long I forget when it started.

I've never seen disc brakes get quieter over time.  It is usually the other 
way round.  The anti-squeel shims must be installed in the proper 
orientation.  Make sure they are not the wrong way round.  The ones I've seen have 
little arrows indicating the direction of rotation.  I don't think being on 
the other side of the equator would necessitate a change in that orientation.  
<grin>

Next I would look into anti-squeel compounds that get applied to the 
backside of the bad.  These are formulated to dampen out the squealing.  I guess 
they work.  The effect is subtle.  

Failing that you may have to look at the discs and pads.  Cheap materials 
will be more prone to this problem and better parts may solve the problem.

Good luck.

Dave
