Pedal Goes to Floor

My daily driver is a honda accord. Today driving home from work my pedal started going to the floor. The first time I touch it it goes to the floor and if I keep on touching it it gets stronger. Just the first time after a block or so, that I touch the pedal it goes to the floor. This is weird because I didn't touch anything. Any ideas on what this might be?

I am assuming you are referring to brake pedal. My gas pedal is usually always to the floor. Is the master cylinder low on fluid? You may have a small leak in a line. If it is not leaking I would say your master cylinder is kaput.

Master cylinder is full and there are no signs of leaks.

I agree.

My truck had a similar problem. It would stop fine, but the pedal would slowly creep down if you held your foot on it. This was particularly annoying at a red light on a hill. As poncho said, it's leaking past the seals internally.

Well, I think I fixed it. I found the right rear wheel cylinder leaking when I pulled back the boot. I replaced the wheel cylinder and blead the system. Drove it around for a while and the pedal seemed to be back to normal. I guess the real test will be driving to work tomorrow morning. Thanks for the help everyone.
