Why Does the Car Clutch Become Lower?

Reasons why a car clutch becomes lower: 1. There is air inside the clutch system, or leakage in the clutch master or slave cylinder; 2. The clutch cable is low, and there is an adjusting screw at the front end of the clutch cable—sometimes if it loosens, the clutch becomes lower; 3. The impact of a low car clutch: if adjusted too low, it can affect the separation gap, causing the car to start in a semi-clutch state, leading to clutch wear, and making gear shifting difficult. The clutch functions like a switch, engaging or disengaging power transmission. The clutch mechanism allows the driving and driven parts to temporarily separate and gradually engage, with the possibility of relative rotation during transmission. A rigid connection cannot be used between the driving and driven parts of the clutch.

I often encounter the issue of the clutch pedal becoming lower. My manual transmission car has been driven for over five years, and now the pedal feels noticeably longer when pressed. The most common reason is excessive wear of the clutch disc. Over time, the clutch disc becomes thinner, requiring a deeper press to disengage the gears. Another issue could be with the hydraulic system, such as old clutch fluid or leaks, which allow air to enter and make the pedal feel soft. Frequent stop-and-go traffic in the city accelerates wear due to partial clutch engagement, while hill starts in mountainous areas are even more damaging to the clutch. I’ve found that regularly checking the clutch fluid level is crucial—topping it up with the manufacturer-recommended fluid can help alleviate the problem. If the pedal continues to sink lower, it’s best to visit a repair shop to replace the clutch disc. Otherwise, clutch slippage can affect power transmission and even damage the gearbox.

I think a low clutch pedal is often caused by issues in the hydraulic system. My old car had this problem before—when the clutch fluid was low or the lines were aged and leaking, the pedal would sink deeper. For example, a damaged master cylinder seal or a failing slave cylinder can lead to extended pedal travel. I've also seen bent release forks or worn bearings causing similar issues. When changing the fluid, make sure to bleed the system properly, as trapped air can make the pedal feel spongy. Avoid aggressive half-clutch driving in daily use to reduce stress on the hydraulic system. It's advisable to check the clutch fluid's color and level every six months as a preventive measure.

The clutch pedal travel becomes longer, simply put, there are several common reasons: first, the clutch disc is worn thin, requiring deeper pressing to disengage; second, there is oil leakage or air in the hydraulic line, or the fluid level is low; third, the pressure plate or release bearing is damaged. Deal with it promptly, don't delay, otherwise shifting will be difficult and it will harm the car. For inspection, first check the fluid level, then test the pedal feel. Replacing the disc often solves the problem.
