Since a couple of months, I have been noticing a squeaky sound coming out when I press the clutch pedal down to change the gears. Sometimes it goes away by itself and sometimes it's really really loud. My mechanic who does the regular service said that it could be master of slave cylinder which might be leaking.
I am not sure if that's the cause. Has anyone faced this issue before?
If I need to get the clutch replaced, how much would it cost and which is the cheap and the best place to get it done. Thanks.
