Instructions on how to adjust the clutch of a car

The car clutch is the part that connects the engine, gearbox and wheels, allowing the wheels to operate in all conditions. Adjusting the clutch pedal helps the engine disconnect from the wheels. Therefore, if the clutch pedal fails, the driver will have difficulty controlling the vehicle, or even worse, not be able to operate it.

How to adjust the clutch pedal of a car

Adjust the opening height

To check the height of the opening lever, you need a measuring tape to check. Use a measuring tape to measure the opening lever tip to the surface of the pressure plate, within the allowable range announced by the manufacturer. When the distance between the opening levers is not equal, it must be adjusted and the difference must not exceed 0.3mm.

Since the lever is mounted on a bolt, you can change the height of the bolt to change the height of the lever. If the end of the lever has adjustable bolts, simply loosen the nut and adjust the bolt in/out in the direction needed.

Adjust clutch pedal

Adjusting the clutch pedal goes through two processes. First is the free travel of the clutch pedal, this is the distance from the pedal to the position where the bearing is completely eliminated free clearance, so when the driver presses the clutch pedal, it will feel heavy. Next is the working travel, when the driver adjusts the operation to the floor of the car, the clutch will be completely disengaged. The standard travel is usually 1 - 5mm.

You can check by asking someone else to push the clutch pedal all the way to the floor to measure the total travel distance. If the total travel distance is higher or lower than the standard, the clutch pedal free travel needs to be adjusted.

If the length does not meet the manufacturer's published standards, use the adjusting screw to change the length of the drawbar.

Bleed after clutch adjustment

To ensure that the clutch pedal's operation is not affected, you need to bleed air after adjusting the clutch pedal. The way to do this is to attach a plastic tube to the bleed air pipe, the other end is inserted into the brake fluid container, then have another person press the clutch pedal and hold it, at the same time loosen the bleed air pipe until you see brake fluid flowing out, then tighten the bleed air screw.
