it sounds like the pressure not building or holding ....
if it had air in the lines the pedal will feel too soft or spongy....which could also be the issue.
try re bleeding again and get a scan tool that can activate the abs pump and bleed it out properly.
if that fails check the vacuum lines to the booster and the booster itself...
if any of the brake hose is damaged kinked ( it will restrict fluid flow ) and it will also cause you to pump the pedal multiple times to get the car to stop..
if you suspect a recall issue .
you should have checked to see if your vehicle falls under the recall and if purchased locally you can have it fixed for free....
if purchased foreign used.... then you maybe in a bit of a bind as you will have to source the new parts and install yourself at full cost to you .!!!
usually when Nissan puts out replacement / upgraded parts .... on the FSM it will show you that and will no longer give you the option to buy the old inferior part - they will instead show you the newer part.
problem is when you go bamboo and buy foreign used - all of those cars that were scrapped ( no matter if its the new B17 sentra ) would have the same inferior part that you trying to replace.
very rare you will find the new upgraded part just sitting there on a shelf used / or on a half cut / nose cut.
so you will have to be weary when buying....
