New clutch problem?
I suggest that you try bleeding the system more first. This is the easiest thing to do and will help you elimiante the "air in the system theory" that so commonly plagues these cars. Then, if the problem persists then you can try check the overall measurements of the assembly to see if you need a shim. I have provided the very informative post from Joey at Tick performance below. It should help you assess your need for the shim.

If the you are confident that you have no air in the system, and your parts are geometrically correct, then try bleeding again. If that doesn cure it you need to start considering an upgrade for your master and a new slave cylinder. If you have any questions about this feel free to contact me at any time. Thanks and have a good morning!
