The working principle of the clutch is that 2 axles and a rotating shaft are connected to the motor. The other column will connect the gearbox and the transmission and the wheel. So when you depress the clutch, the two axes will separate and the shaft connected to the rotating motor and the other shaft won’t. Then, when you release the clutch, the two axes will immediately touch each other and the friction will cause the shaft connected to the intermediate gear system to move.

After that, the next journey to the floor of the car is called the work trip (to cut the clutch completely). And the total of those two journeys is the total journey.

The free play is the journey from the moment the clutch is pressed until the weight is felt

First, you will measure the height of the pedals by using a ruler perpendicular to the floor, if the height is correct according to the regulations of each car manufacturer. If the standard is not correct, the height must be adjusted to correct by changing the length of the bolts. Then, have someone else pedal the gas pedal to the floor to measure the total travel distance. If the total stroke of the clutch pedal is lower or higher than usual, the free travel length of the clutch will have to be rebalanced, for example, for Toyota vehicles the free stroke length of the clutch is 5 – 15mm.
