Well, I had some success. There is a 2mm allen screw on the brake pivot pin. I removed that, and then removed the pivot pin with a punch. This allowed me to unscrew the the phillips head behind the down shifter which then relaeses the brake lever.
Upon inspection of the mechanism, I figured out that the pawl which enguages the entire mechanism for up-shifting was full of solidified grease and was no longer springing properly. A blast and clease with WD-40, then oil, then greasing the ratchet mechanisms has resulted in it working as good as used. The whole thing, including re-assembly took about 40 minutes.
I can see if anything actually breaks or totally wears out, fixing it would be very difficult as it appears that the pawls and spring axles are a press fit into the shifter body. However, for just cleaning the bugger out, it is servicable.
If anyone has some more defunct RSX brifters, I'll take them as spares for when these finally explode.
