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
