Clutch, defender 90

I had the clutch replaced two weeks back as the car would not go into gear. As I and the garage have fixed major mechanical faults it's been running sweetly up until now. The clutch began to get slack, like when the foot went on it it was loose and has begun to get looser. What I'm curious about is if it's just because it's new and has been broken in or it is broken and needs sorted. Thanks

I'm not fully sure what you mean, but I'd be checking if there are any leaks around the slave and master cylinder

Nuts on the master cylinder rod loose?
