I am looking for a front brake caliper rebuild kit for my 1999 ZX9R; it has two front calipers and they are both six piston calipers. They are made by Toxico if anyone can help please let me know, I have a PM sent to TFOG. This kit is proving hard to find on the net was wondering if rubber "o" rings could be used to rebuild the calipers, if anyone has any input please educate me.
