Thanks for all those who offered advice on y previous question. We tour in Japan and can easily spend 1 hour going down mountains, which explains in part my wife's fatigue from endless braking. The simplest solution offered was related to brake pads and specifically the koolstop salmon. I have found them online and just want to check that these are indeed the correct ones for stock Long Haul Trucker brake hardware.
