I went to the local hardware store and bought O-rings (2 plus 2 spares) that fit snug into the grooves, and are also a snug fit on the pivot. With a little grease they slide/seal good. I also drilled the brake pedal for a grease fitting, adding grease and pushing out any debris is now simple with out disassembly, and that was my goal. Look at any of these and you will find the pivot is rusty, not mine.desertR
