My clutch on my punto keeps kinda going ....cant select gear very well at all.

so i got the slave cylinder off pushed in the piston my pedle was flat ont he ground by this time so that flicked up. got a friend to push down on the pedle slowly the piston in the slave cylinder was moving out nice.

anyways put it all back together tested my clutch out throught the gear box, then went out for a spin and seemed to be working fine.

after a week it started becoming hard to select gear again then did the same as last time. so i made sure no fluid was coming out checking or patches and levle. that was all OK!

so i guss its the master clyinder....
