So lately the car has been doing this weird thing where after driving for a while the clutch pedal seems to have like an inch or so of play at the top. Like when you start to press the pedal down there seems to be like a dead spot as soon as u touch the pedal then feels normal the rest of the way. Changes gears fine etc. When i start driving in the morning it’s normal. Happens after driving a while. Can this be air in the system, slave, master cylinder? Haven’t seen any fluid dripping behind pedals or anything like that. Any ideas?
