What Causes the Clutch Pedal of a Manual Transmission Car to Stay Down When Depressed?

When the clutch pedal of a manual transmission car stays down after being depressed, it is usually due to a disconnection or jamming in the clutch pedal, clutch master cylinder, or transmission mechanism. Other possible causes include: Air entering the clutch hydraulic system, leading to excessive clutch travel and poor return; Contaminated clutch fluid with impurities, causing severe wear inside the clutch master cylinder (piston) or blockage of the return oil hole, preventing the clutch from returning; As the vehicle mileage increases, the clutch return spring may lose tension or break, resulting in the clutch pedal not returning; Excessive wear in the clutch linkage push rod causing poor return. Solutions: Avoid prolonged use of the clutch in a semi-engaged state; Fully depress the clutch pedal before shifting gears; When performing emergency braking, simultaneously press the brake and clutch pedals. The clutch is located in the flywheel housing between the engine and the transmission, secured to the rear plane of the flywheel with screws, and the output shaft of the clutch serves as the input shaft of the transmission.

When I first learned to drive, I also encountered this issue. The clutch pedal felt spongy and wouldn't spring back. Later, my instructor taught me to first crouch down and check for any signs of leakage around the clutch slave cylinder. If the area around the slave cylinder was wet, there was a high chance the oil seal was broken, leaking hydraulic fluid. Then, open the engine compartment to check the fluid level in the clutch master cylinder reservoir. If the fluid level was critically low, air could enter the system, causing the pedal to feel soft. I remember one time when my clutch pedal got stuck; the emergency fix was to repeatedly pump the pedal hard a few times to force the air out, barely managing to drive home. You really shouldn't push your luck in such situations—if the slave cylinder fails completely, the car won't be able to shift gears at all.

Last week, I helped my elderly neighbor deal with the exact same issue. His old car hadn't had its clutch fluid changed in five years, and the fluid had turned black and gummed up. When we lifted the dust cover of the clutch master cylinder, it was full of solidified sludge. In my opinion, mechanical cable-type systems are even more troublesome. If the release fork shaft rusts and seizes, you might have to remove the entire transmission. At that time, it took half an hour of spraying rust remover on the release fork shaft to loosen it up. You folks in the south should be especially careful during the rainy season—high-pressure water jets washing the undercarriage can cause the release fork shaft to rust. Additionally, if the release bearing on the pressure plate seizes, it can prevent the pedal from returning, and fixing this requires removing the transmission.

There are three common causes: hydraulic system failure is the most critical, as internal leakage in the master cylinder prevents the brake fluid from returning; mechanical jamming is also frequent, with rusted shift fork shafts or lack of lubrication on the clutch pedal pivot causing stiffness; a less likely scenario is a broken diaphragm spring on the pressure plate. Just yesterday, I repaired a car where the release bearing sleeve guide was deformed and stuck on the guide tube. In summer, special attention should be paid to clutch fluid evaporation due to high temperatures—I recommend changing the fluid every two years. For emergency fixes, try pulling the pedal upward while someone pushes the car to engage the gear using inertia.

Which is more fuel-efficient, normal mode or eco mode?

eco mode is relatively more fuel-efficient. The relevant information about normal mode and eco mode is as follows: Concept of normal mode: Normal mode is the standard driving mode, which is the ordinary mode when driving a car. Normal mode is suitable for urban driving. When the car is in normal mode, the car's transmission and throttle will be in a relatively balanced state, making the occupants more comfortable. Concept of eco mode: Eco mode is the economical mode. When the vehicle is in this mode, the throttle response becomes more sluggish, the transmission shifts more proactively, and the engine speed is maintained in a relatively low range, thereby achieving the goal of fuel efficiency. Difference between normal mode and eco mode: There is a difference in energy consumption. Eco mode operates in a low-energy and environmentally friendly state, while normal mode operates in a standard power consumption state, with normal mode consuming more energy than eco mode.
