I had this problem on my car after changing the clutch, although mine is a mash of parts what we found may help.

For a start, it would be wise to fit a new cable or at least measure yours.

Did you replace both the quadrant and the pawl??

and are you sure it was the right ones??

Mine was fucked so was replaced. The only difference between most of them is the depth of the groove that the cable sits in. Deeper the groove, the less the cable is capable of being moved.

Before swapping quadrant, my pedal was like yours, it didnt quite fully release the clutch with the pedal mashed into the floor. However just swapping to a quadrant with a more shallow groove (and hence more cable travel) has solved the problem. My clutch now releases about 1/3 to half way up the pedal leaving plenty of travel for future wear.
