In the past couple days i noticed that my clutch pedal will push in almost an inch before it will engage. I have 99 gs with hydrolic clutch i checked the clutch fluid 2 days ago it was low, i filled it then, today i checked fluid and it was fine. yet still no change in the pedal, and its starting to shift hard. are these signs of my clutch wearing down an needing replaced or is it something else?
