Changed my front pads yesterday, the old ones were getting very thin!!

All working OK, everything tight etc. But they make a chirping noise at 30-40 mph. When I pull the lever in it disappears and then let it go and it comes back sometimes. Not sure if it happens at higher speeds as I can't hear it. Is it the pads bedding in or have I done something catastrophic with my inept sausage fingers?

OEM Honda pads btw, only done 30-40 miles on them. Discs seem OK, not rattling or anything.
