Sounds like the master cylinder.
But, since it's already been replaced, you may have air in the system.
Might be a leak too.

did you bleed them?

also did you replace it with a new master cylinder or used?

i replaced it with a new one im thinking it may be a faulty master cylinder. i had the shop bleed the system like 4 times how could i test to see if the master cylinder was no good ?

If the system has been bled properly and the pedal still goes to the floor, then your master cylinder is probably no good. It happens, especially with cheaper aftermarket parts... though it can happen with brand new Honda units as well.

The only real way to test it is to have a different shop bleed the system... make sure that it's not an error on the side of your shop. Otherwise, assume that your new part came busted, and try to get a replacement for it.

If the shop didn't bench bleed the master cylinder, that makes it an absolute PAIN to bleed the rest of the system properly.
