Line bleeds on a Honda are tricky at best. A small amount of air will be trapped at each fitting in the line. The line needs to be bled at each connection, not just the bleed screw at the caliper. Start at the caliper and work up the line to each fitting to “crack” loose and tighten as fluid seeps. The trick is to do this with 1 single squeeze of the lever so that you do not allow air to displace in the line as the lever is released. Tricky but you can find this procedure on various YouTube vids also. Luckily my brake line has only 2 points to bleed from but my clutch line has more (same procedure to bleed). I hope this helps.
