I've done some of the other suggestions that have been made. What I've
settled on is what I saw in a Kawai-made Howard grand. Saw it, liked it, and
now copy it. :-)

Put a leather punching (disk?) at the bottom of the pedal "cup", then bush
with action cloth. A little PVC-E glue to hold the cloth in place, but make
sure the glue doesn't get on the leather. The old rubber gunk from the pedal
rod gets cleaned off, the rod polished with Flitz, and then add a little
Teflon powder in the new for insurance against squeaking. (Though I doubt it
will ever squeak, and probably never like the nasty rubber ones.)

I have a little leather and felt kit that has the leather punchings already
punched out (in a baggie), and some action cloth ready to be cut to size.
The leather came from Pianoforte Supply (bought at a convention sometime).
The action cloth is the medium green stuff ... from Schaff, I think.
