Bleed The Brakes?

[SHANE03EX]

I took my 400ex apart last weekend to clean it. I took the a arms off and in doing that I also took off the brake calipers. I left the pads in the calipers and let them hang. Now I have everthing back together my front brakes work, but not very well, the lever pulls all the way into the handle bar very easily with not much effort. I think the brakes lines have air in them, but how could air have gotten in there? Any thoughts?

The air is not cause you took them off. and there is no way air can get in. is your fluid level low? It just happens . Just add some fluid or bleed you brakes and you'll be OK.
