Release the slaves bleeder and see if the rod retracts. If it does start adjusting per the fsm. There should be free play at clutch adjustment rod with the s/c piston fully retracted and return spring on.
Checkout the push rod. My guess is the masters pushrod loosened up and is out of adjustment. Be sure there's a return spring on the throw out bearing fork and the t/o bearing is not riding on the pressure plate at rest. #3 adjustment is not when you feel pressure, it's when the slave starts moving.
