replace the brake master cylinder ASAP.. use a Honda cylinder and make sure you bench bleed it before installing it in the car ..

 

Along with replacing the Master Cylinder, Have the COMPLETE brake system flushed; or you'll be right back a year from now doing the M/C again. (along with every other cylinder in the system.
The brake fluid has become supersaturated with water and has started corroding the cylinder bores.

And please, stop driving it until you get it fixed.

 

dude, this is a serious problems.
Have it inspected at any shop or do it yourself ASAP.
