Today driving to school I was going down 140th and I could put the pedal to the floor and I cant figure out why, I can build pressure in the lines if i let the brake pedal out all teh way and then push it in, but sometimes it hit the floor and i wouldnt stop. I have checked the lines, no leaks, I checked the master, theres plenty of fluid in it. My brake pads are close to new. Can anybody offer some insight?

The seals in your master cylinder could be shot. What kind of vehicle are we talking about?

You may want to check your wheel cylinders in the rear for leakage?

Any idea on how air got into them??
its a closed system isnt it?

How can I check the rear, just look for liquid on them?

To check the rear you have to pull the rear tire and then the drum. The wheel cylinders will be at the top. They look like, well cylinders.they may be leaking from eithier or both ends..
