Interesting point. I revise my first thoughts...Steel on brass has a
lower coefficient of friction. Also, if you note, many moving parts in
cars are brass-to-steel. Important point, however, is that if brass is
used, you must make sure that their is a thourough coat of rubber
lubricant where the piston meets the brass...
Cheers..
