my clutch a few weeks ago was getting very loose like it had no pressure till the clutch literally caught on the floor. i bled it and it worked for about two weeks now it is really loose agian i bled it agian today it worked for a few hours now its back on the floor, i heard it was the master clutch cylinder or the slave cylinder or both, is that the problem?

 

look at your fire wall inside above the clutch pedal ...
clutch masters leak ...you will see fluid there
I would just replace both never replace just one
there not very costly
