Check all lines, including brake-lines for leaks before you do anything else. Check for progressive fluid loss in the reservoir. Make sure all nipples are fully tightened. Some fluid will appear to be "lost" as the new brake pads bed in. Examine clutch slave cylinder while someone else presses the pedal down, checking for leaks from the slave and any over-travel or restrictions in the linkage. Check under the panel above the clutch pedal for clutch master cylinder leaks into the cabin and any sticking mechanicals or piston over-travel or restrictions. If all these appear fine then you can start to examine the problem further but not until these basics are done.
