hello everyone. i am new to this forum so please bear with me... i just recently change my clutch kit, and slave cylinder... i bleed it and everything at least 10 times.

here's the problem now..... the first few weeks, the clutch was pretty low when taking off from 1st gear... but all of sudden, i had to let go of the pedal real high before it engages in 1st gear. so i bleed it again.... now back to normal again. barely let go of the pedal on 1st gear and it goes.... but, a few weeks later its doing it again... could it be the master cylinder is bad??? since i changed the clutch kit, and slave cylinder.... it seems like its not holding preesure. I checked all the hydraulics lines for leaks, but nothing... sorry for the novel i wrote, but can anyone help me out???
