Clutch Pedal Problems

I have a 2000 SS Camaro and i bought it from a private seller. When purchased it had 44,050 and now has about 49,000. The clutch pedal is beginning to act wierd. When holding down the pedal if i am shifting 1st to second or on down the line it is fine but from reverse to 1st the pedal doesnt come up all the way. I can lift it up to normal position and pump it a few times and then it goes back to normal. But if i put my foot on the pedal and hold it i can feel the pedal slowly going to the floor. I think it could be the Clutch Master Cylinder. So if any one has sugestions it would be greatly appreciated.

Thanks,
Chris
