Brother in law has just bought himself a Trek 3500 disc for commute and it says it has 'Shimano HL 280 mechanical disc brakes'. I can't find the part on Shimano's web site and can't find which pads he would need.
He's completely incompetent at mechanical stuff (even more than me!) so does anyone know their 'true' part number and which pads to get? I can then source some spares and send them on.
He's in Norway, so not easy to take a peek.
