OK, I got a bit sloppy. Pulled the pads to check wear, putting all the parts in a magnetic tray. Everything was fine up to the last step, installing the safety clip. It popped out of the small needle nose pliers and, predictibly, it disappeared onto the concrete shop floor. Never did find it. It's fine without the clip, until it's not. I picked up a replacement clip at the local hardware store, having to bend it 90 degrees. It's not really the right size, but for $0.19, it's working. Went by yesterday to get the right sized clip, but new 'social distancing' rules were in place. The line went out the door. Found the correct clips online for more $, but no waiting in line for almost the right part. Ordered a couple of spares, too.Bedding new pads is recommended for all pad types. It is necessary for sinthered/metallic pads like the Specialized J04s, but becomes less necessary with lower metal content. Organic resin pads, like the Specialized J03s you're using can do without being bedded in but the braking power will be reduced for a bit while the pads surfaces wear to the rotors.
