Thanks for the reply.
Hadn't thought about the possibility of the bleeders being blocked. I'll take one off and check it out. Your bleeding sequence is different from what I read in a scanned copy of a service manual published by Honda, although I'm not sure that matters at this point.
Wondering if my "assistant" might have damaged the new MC by going to the floor? Would that affect only these two wheels? Could that be the noise I'm hearing around the LF caliper since it's not far from the MC?
