From time to time when i press on the brake pedal it feels real spongy and depresses all the way, and it is very hard to break, what should i be looking for to solve this problem? Should i maybe bleed th breaks?, thanks

Try bleeding the brakes first, but sounds like master cylinder need replaced.

Yep, same thing happened to me about a week after I got my Integra up and running again. I bled the brakes but while I was holding the pedal down with all bleeder screws closed, the pedal slowly went down to the floor as if a bleeder was open. I replaced the master the following day and problem solved. Just make sure that you bench bleed the master before installing as it will make bleeding the system much easier.

Yeah, it's either a leak in your MC, or even possibly a leak in the brake lines. Although it is much more common that it's the MC.

sounds like the o-rings in the master cylinder are gone and the fluid is just passing by them leaving you with the pedal slowly going to the floor
