hks

my car clutch doesnt feel the same. the pedal feels way too easy to press and when starting the car i have to sink the clutch all the way or i-drive will say sink clutch to start. also my brake fluid low level reading came on two weeks ago. not having have gear grit issues im thinking maybe air got in the line or something, maybe even the cylinder. however someone was telling me if it was the cylinder it would be stiff instead. any suggestions?
