Scenic clutch pedal

Thanks in advance for this forum. I have a Scenic (from 2006) and what happens is the following: the clutch pedal does not make its \ "return \" until the end. He who gives very little and with the help of a simple standing blow ends up recovering. I have already changed the clutch bombin (a piece that is behind the pedal). Could I bend to the pedal area and grease that pedal or press any screw to give it any solution? The journey that the pedal is completely missing is very little to return. Thank you very much and greetings
