Brake Issues

What would make the front brakes first still grab, but now seem like there is not much brakes at all. I started out with my front brakes sticking, so swapped out the calipers and brake lines. At first there was no change. Now it seems like there is little to no brakes. The pedal goes to the floor. Any help would be appreciated.

Sounds like you may have some air in the lines. Make sure they are bled properly...only thing else is the master cylinder going bad or getting plugged.

I'll try bleeding them again. If that don't help then I will look into the master cylinder. Thanks.
