Ok so heres the problem, I've bought the car about less then a year ago, immediately changed the whole clutch set, but the pedal was still dropping to the floor, not at all times mostly when I'd drive it for maybe half an hour, and it drops only when in gear, when it's not the pedal works normally. Now I've changed both hydraulic cylinders and bled the system, but the problem wasn't fixed. Also now it started to whine when the pedal is pushed, and when it releases... Can someone please help??!
