Soft clutch pedal: PPlate? Lines? Slave? Master?

Yea, that was the last thing that they tried and it worked, not sure why, could have been just the fact that the boot was off and the gunk had collected inside but I drove the car before and at random times the pedal would go sluggish, at one time the car had the same problem, wouldn’t go into any gears, but after the new boot and the bearing being greased, it was fine. It’s been over two weeks and no problems.
