When is the last time you changed the fluid? You can also check when you do that maintenace item that the fluid is flowing through the system. There is a small hole in the side of the master cylinder that allows fluid from the reservior to access the rest of the system. If that is plugged it could cause a stiffer pedal.
I filled the fluid up couple of days back.
The last time the fluid was flushed, was when I changed the clutch four years back.
Like you said, I will change the fluid and will look for the hole in the master cylinder.
thanks for your help.
