What is the reason why the h6 clutch does not bounce back after being depressed?
4 Answers
Clutch cannot rebound after being depressed for the following reasons: Air is mixed into the clutch pipeline system, causing excessive clutch travel and poor return; The clutch fluid is too dirty with impurities, causing severe wear of the internal piston of the clutch master cylinder or blockage of the return oil hole, preventing the clutch from returning. Here is the relevant introduction: 1. Haval h6: The Haval H6 is the flagship model of the Haval brand. On August 25, 2011, the Haval H6, positioned as an urban intelligent SUV, was grandly launched at the Great Wall Motors Tianjin new factory. It provides Mitsubishi 2.0L gasoline power models and Green Power 2.0T diesel models, divided into three versions: urban, elite, and noble. 2. Clutch: The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can depress or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, to cut off or transmit the power input from the engine to the transmission.
That day when I was driving, the clutch pedal got stuck after being pressed down, leaving me flustered. I've encountered this issue before, mainly due to problems with the clutch hydraulic system, such as aging or leaking seals in the master cylinder, which prevents proper oil pressure buildup. Sometimes, when the brake fluid in the reservoir is nearly empty, air enters the lines and forms bubbles, making it impossible to transfer hydraulic pressure when pressing the clutch. Another common cause is a faulty slave cylinder, where the push rod gets stuck and fails to retract. Alternatively, the clutch disc might stick to the flywheel due to overheating after prolonged high-speed driving. Occasionally, rusted or loose springs or lever mechanisms can prevent the pedal from returning. This issue is dangerous—if it happens at an intersection, it could lead to a collision. It's crucial to visit a professional repair shop immediately to check the fluid and lines. For regular maintenance, remember to change the clutch fluid periodically to minimize such failures in older vehicles.
I've been into cars for over a decade, and it's really frustrating when the clutch pedal doesn't spring back after being depressed. The issue mostly lies in the hydraulic system: the master cylinder piston wears out and leaks oil, resulting in insufficient pressure; the slave cylinder push rod gets stuck or the seal ring breaks; air enters the oil line, creating air resistance that hinders the return flow. It could also be due to excessive wear of the clutch disc sticking to the flywheel or a failed release bearing jamming in the bearing seat. When checking, see if the fluid level in the reservoir is low or if the pedal linkage has enough lubrication. If you feel the pedal is soft or stuck while driving, pull over immediately. Don't force it, as it could damage the transmission or cause an accident. You can temporarily add new fluid and bleed the system yourself, but for a permanent fix, take it to a repair shop to replace the parts.
The clutch pedal not springing back up is quite scary, I've experienced it. The main causes include oil leaks leading to insufficient hydraulic pressure, or air bubbles in the lines. It could also be due to a broken spring or a seized release bearing. Another possibility is wear of the clutch master cylinder causing seal failure. Stop the vehicle immediately to check the fluid level, safety first. Just get it repaired at a service shop.
