brake problems

I noticed yesterday that my brakes felt a little low, then it went straight to the floor so I just figured one of my lines blew. I pulled over to check it out and not a single drop of fluid on the floor? Opened up the resevouir and it was full too... I'm starting to think its the master cylinder just going bad. I did notice that if I keep my foot on the brake pedal it will hold pressure but as soon as I let off even the slightest and push back in, it goes lower and lower until I have no brakes at all, then if I let go and wait a minute they work as long as i hold it steady and don't let off. Any ideas?

EDIT: I just did both front calipers and bled the system out correctly.

Did you just replace both calipers? The common thing is to put them in upside down. Is your bleed screw on the top or bottom? If it is on the bottom of the caliper you need to flip them.

It does sound like the master is going bad; you can usually get OK pressure by quickly applying the brakes, but lose it with your foot sitting on the pedal. Time for a new one! Don't forget to bench bleed it before hooking up the lines.

Ditto, common mistake and I did it myself. Look at your calipers. The bleeder must be on the top. The calipers have a left and right side.

Both are on top, I think I know what's wrong with it, called up my dad and told him what was happening and he told me that he was checking it out and noticed brake fluid was a little low so he filled it with power steering fluid : gonna try bleeding it all out today.

Oh no!!!! I hope you can save the flexible lines a reservoir. My son's buddy did the same thing. Cost him $400 to get fixed.
