94 Accord EX-R clutch issues
 

My parents have a 94 Accord EX-R (Canadian model). Lately, the clutch pedal feels no resistance. I've replaced the clutch fluid and bleed the system. It's almost fine for a week or so and then it goes back to really soft and sometimes the pedal stays right at the floor.

Would this be the master or the slave cylinder gone bad? I can't see any leaks.

Is there a way to test this?

Also, how to remove the master clutch cylinder? I've done the slave on my civic before so I know.

if it stay to the floor it's probably the master. if it leaks, it will leak on the inside and run down into the carpet or inbetween the firewall.

the master has like two bolts accessed from the engine bay and the rest is under your dash.
