Are you bleeding the brakes in the correct sequence? It goes: RR, LF, LR, RF.
I just replaced my m.c. in my '96 Accord. The pedal would slowly go to the floor at stop signs and lights. The brakes worked good, but the pedal wouldn't hold and the car would start moving. The m.c. switch was not a hard project. The Haynes manual did a good descriptive. Good luck.
