What's the reason for noise when stepping on the clutch?

The reasons for noise when stepping on the clutch: 1. Wear of the clutch disc, causing abnormal noise from the clutch release bearing, which is usually quite harsh; 2. Abnormal noise caused by broken clutch pressure plate springs, loose release bearings, shattered clutch steel plates, broken or excessively worn clutch release levers, or broken adjustment bolts of the release levers; 3. Slight wear from long-term use of the clutch pedal support shaft, where some lubricant can be applied; 4. A hissing sound when stepping on the clutch is mostly due to abnormal noise from the clutch release bearing. Many car owners have the habit of keeping their foot on the clutch pedal even after shifting gears. Maintaining this habit for a long time can cause damage to the clutch.
Having driven for many years, I've encountered situations where the clutch pedal squeaks when pressed. This is usually due to wear or lack of lubrication in the clutch release bearing. When the bearing rotates as the pedal is pressed, it makes noise, and insufficient lubrication causes friction that results in squeaking. Another common issue is rust in the linkage or cable of the clutch pedal mechanism, which can produce a creaking sound. This is easy to check—just spray some lubricant or WD-40 to test. If the sound is deep with a clicking noise, be cautious as it might indicate a failing release bearing or worn clutch pressure plate. This needs immediate attention, as ignoring it could lead to gear shifting failure, which is particularly dangerous. I experienced this with my old car—after simple lubrication failed to fix it, I promptly took it to a professional repair shop to replace the parts. It didn't cost much but prevented potential accidents. As a long-term driving habit, lubricating the pedal joints every few months can significantly reduce noise issues.
