Default Sinking break pedal

Hey guys,
Recently I've noticed that sometimes when I press on the breaks the pedal sinks slowly towards the floor. I've been told that its most likely the master cylinder, however, It has been only happening on hotter days rather than cold/cool days. The break fluid is always full and has not gone down at all. So im assuming no leaks. And the sinking only happens everynow and then on hotter days. Sometimes it sinks, and at the next red light it could be fine. If anyone has any input on this feel free.
thanks!

That's classic for a bad master cylinder.

It's the Master Cylinder. There is a DIY on page 3 of the DIY section. I had the exact same problem on my 95. I followed the DIY posted by deserthondaand replaced it about a year ago. Not too hard if you have 2 people working on it.I went witha new MC from hondaautomotiveparts.com - I would stick with Honda OEM for this part. I am a big time cheapskate, but I didn't want to skimp on a part so critical to stopping the car.

Had a feeling it was the master cylinder. Just needed some second opinions to confirm it. Thanks for the input!
