(Assuming you have a hydrolic clutch system)
When you push on the clutch pedal, you create hydrolic pressure in the master and slave cylinders, which in turn pushes on the release bearing (AKA throw-out bearing). The release bearing pushes on the fingers of the pressure plate. This takes pressure off of the clutch disc, putting the car in neutral, in a sense. Now you can change gears without damaging any of the transaxle gears.
When you release the clutch, you put pressure back onto the clutch plate and pressure plate, which gives power back to the wheels if you are in 1st-5th gear, or reverse.
The clutch is the pedal you press to change gear.
The clutch pedal usually squeaks where the clutch pedal is mounted under the dash. The clutch pedal pivots at its mounting point so it probaly just needs some lubed sprayed on it.
The pedal on the left is the clutch. You press it when you are changing gears.
clutch pedal free play decreases
hi i want to know why when i press the clutch i hear noise
Could be a bad clutch plate, failing throw-out bearing, or other issues. If soon you press the clutch pedal and nothing happens, one of those mentioned is the most likely reason.
that is the wheel getting ready to change gear
In a vehicle, if the radio goes off when the clutch pedal is pressed, there could be an electrical issue. A professional mechanic can diagnose the exact reason.
Either the brake and clutch pedal assembly needs lubrication or you have a size 14 shoe.
Either the drive belt is not releasing far enough when you press the clutch pedal or the brake is not engaging enough. You will need to see if the belt is still turning when you press the clutch pedal down.
youre lifting the clutch up to quick
You will eventually lose clutch pedal pressure and the car will refuse to shift into gear.
