Toyota Corolla Clotch 2007 too hard

Who can help me with this little problem, 4 months ago I changed the full clotch (dish, disc, necklar) to my Toyota Corolla 2007 (Venezuela) and now presents that the Clotch pedal has been hard, I appreciate your help to solve this problem. Greetings

First of all the Cluch is hydraulic or mechanical or has Guaya or Bombin.-

Hello friend, you mentioned that you changed the complete clocht kit (disc, plate, necklace) you don't mention whether it is hydraulic, mechanical or chicote, and you must mention how you changed it, if it was already hard before changing it or changed it for what the changes no longer entered and if you changed it and whate hard or kedo blandito, or if you put it on it. He got hard. And how long you have to put it, but if it is from Chicote Ami Experience that system over time they get hard with the use, for the internal wear of the lining where it works it is spending.

It is hydraulic

Hello, the clotch is hydraulic, I changed it because they did not want to enter the changes, but every first and retro.
At first it was soft, but now the pedal is hard
