So I got some new rotors for my bike. While I was waiting for the rotors to be delivered I inspected the pads. They have plenty of life left in them but I noticed one pad was slightly unevenly worn. One side of the pad has about 1mm more material than the other side. This was likely due to a caliper issue which I have since taken care of. I'm just wondering if the pad is ok to still use.
You could probably use the old pads, but I would use fresh pads on new rotors. If you do use the old ones, put them on a belt sander to remove any glaze and expose fresh friction material, and regardless of using new or old pads make sure you bed them in properly.
Yup. What ^^^ he said.
New pads are cheap. Think of this as an excuse to try a new compound with a little more/less bite than stock to see if you like em.
