Do you own a manual transmission vehicle featuring a clutch pedal and other manual controls? If yes, you ought to be much more careful with your vehicle than the users owning an automatic transmission car.
Though there is no need to mention the importance of a clutch pedal for a manual vehicle here, as you might already be aware of it, let me briefly revive it for you.
The clutch pedal is meant for connecting and disconnecting the engine of the car and its transmission. Using this pedal, you can make or break the connection between the engine’s power and wheels.
However, sometimes the clutch pedal sticks to the floor for various reasons, including lesser transmission fluid in the vehicle, air bubbles in the hydraulic system of the car, faulty master cylinder of the clutch, damaged clutch cable, and many others. This eventually prevents you from operating your vehicle rightly, leading to accidents.
We have come up with a comprehensive guide for you explaining some of the main reasons for sticking the clutch pedal to the pedal. We will also explore multiple fixes for this problem and answer some questions regarding this issue.
Causes of Clutch Pedal Stuck to Floor & Its Fixes
There could be many potential causes for the clutch pedal sticking to the floor. It could be as minor as air in the engine line and complicated such as a damaged salve cylinder or clutch cable.
After thorough research on this problem, we have made a list of all the possible reasons for the clutch pedal sticking to the floor, along with some fixes you can try to eliminate this problem. Let’s explore them in detail.
Faulty Clutch Master Cylinder
One of the major reasons for the stiffness of the clutch pedal is the issue with your car’s clutch master cylinder. If you don’t already know, the clutch master cylinder sends the fluid to the shovel cylinder, which later works to activate the clutch.
If the master cylinder is damaged or faulty, the amount of fluid being sent to the system won’t be enough making the clutch pedal stuck to the floor. You may also feel that the pedal has gotten a lot spongy. Similarly, sometimes due to this, the pedal can also pulse once it receives pressure.
One of the signs that will help you recognize the fault with the master cylinder is that you will find the system fluid on the ground. However, to be sure that the problem-causing agent is the master cylinder, it’s best to get it checked by a professional.
Weary Clutch Release Bearing
Once you press the clutch to disconnect the connection of the engine power with the wheels, the component responsible for beginning the pedal back to its prior position is the clutch release bearing. So, if the bearing is pretty old and has worn out over time, this will prevent the pedal from returning from its depression, thus making it stick to the floor.
To ensure the release bearing wears off, you must first get rid of the dust cover at the back of the clutch pedal. Move towards the next step by pressing the clutch pedal down and keeping it pressed. Make a friend of yours to check if the bearing is moving freely. If pressing the pedal hasn’t made the bearing move freely, it might be a problem.
Bubbles In Hydraulic System
Air bubbles in the vehicle’s hydraulic system could also cause the clutch pedal to stick to the floor. As mentioned earlier, the proper movement of transmission fluid plays a crucial role in keeping the clutch pedal going. However, air bubbles in the hydraulic system will affect the clutch’s fluid ability to pass through the system. This will eventually give rise to many problems, and the pedal sticking to the floor is one of the most prominent ones.
You can remove the air bubbles in the system by simply bleeding the clutch line. The best part is that this process doesn’t require professional knowledge and experience; you can do it independently.
If this is your first time trying to bleed the clutch line, seek help from this YouTube tutorial:
You can also follow this step-by-step guide to bleed the clutch cylinder.
- Firstly, find the bleeder valve in the clutch salve cylinder. You can find it either on the top or on the side of the cylinder.
- Using the brake bleeder kit, i.e., attaching it to the valve, open the valve.
- Make your friend press the pedal a few times till all the air bubbles are removed.
- Once you have gotten rid of all the air bubbles, close the valve and make your friend let go of the pedal.
Note: You might struggle in the beginning while locating the bleeder valve. To save energy and time, it’s best to use your vehicle’s user manual for help.
Problematic Throw Out Bearing
When it comes to the clutch system of a vehicle, the throw-out bearing is a crucial component. It makes the clutch disconnect itself from its functionality once you press the pedal. Owing to this, it’s evident that if there is some problem with the throw-out bearing, the clutch won’t be able to rise again after moving down, resulting in sticking to the floor. This can affect the overall driving experience as you won’t be able to change the gears correctly on your vehicle.
Faulty Clutch Slave Cylinder
Another significant cause of sticking the clutch pedal to the floor is the faulty clutch slave cylinder of the vehicle. As far as the slave cylinder is concerned, it activates the clutch whenever the pedal is pressed. Any problem with the slave cylinder will prevent the clutch from working properly, resulting in the pedal being stuck to the floor.
Additionally, sometimes the problem with the slave cylinder is so severe that you cannot help but notice the system fluid leaking from it.
Contaminated Hydraulic Lines
If you haven’t gotten the hydraulic lines running from the master cylinder to the slave cylinder cleaned for a long time, dirt and dust could have contaminated them. This is one of the major causes of why your clutch pedal is sticking to the floor.
To overcome this problem, you need to clean the hydraulic lines. For this, remove the lines from your vehicle and use a brake cleaner to clean them thoroughly. Once done, install them back into their position. You can also seek professional help reinstalling hydraulic lines if this is your first time.

Damaged Clutch Cable
This is one of the most common reasons for sticking the clutch pedal to the floor. As evident from its name, a clutch cable connects the clutch pedal to the throw-out bearing (we mentioned above).
Any damage to the clutch cable can cause the clutch pedal to stick to the floor. If you observe carefully, you might be able to trace the broken part of the clutch cable.
This issue can be resolved by replacing the damaged clutch cable with a new one. Be extremely cautious during installation if you don’t want to follow the wrong route.
Less Transmission Fluid
As mentioned above, air bubbles in the transmission fluid are one of the significant causes of the clutch pedal sticking to the floor. Owing to this, it’s crystal clear that transmission fluid is highly crucial to keep the pedal going.
But what if the fluid in the system isn’t enough? This would not only lead to the drying of many clutch system components but will eventually lead to the clutch pedal being stuck to the floor due to a lack of pressure to lift it up.
To avoid this issue, it’s best to keep an eye on the transmission fluid level in your vehicle. For this, here are the steps you need to follow:
- Find the dipstick on the side of the vehicle’s transmission.
- Remove the stick and clean it.
- Put the dipstick back and eliminate it again to see the transmission fluid level in your vehicle.
- If the fluid level isn’t enough, fill it until it reaches up to the line on the dipstick.

Absence of Connector Rod
Though a connector rod is a tiny piece that links the pedal to the pushrod, and you won’t really notice if it falls somewhere, its absence can cause the pedal to stick to the floor. So, if you don’t want this to happen with your vehicle, check for the connector rod every time you take your vehicle out. Also, it’s equally important to ensure that the rod isn’t worn-out.
Varying Clutch Components
Another thing that results in sticking the clutch pedal to the floor is the varying clutch components. Simply put, for the clutch system to work properly, the working intensity of all the components needs to be the same.
For example, if the pressure plate of your vehicle is way too robust compared to the clutch disc, the pedal will stick to the floor. It’s because, due to the high pressure, the pedal won’t return to the original position once depressed.
No Clutch Assist Spring
The last reason we have figured out is the absence of a clutch assist spring. To figure this cause out, you don’t have to be an automobile enthusiast or professional. All you need is a bit of common sense. When the pedal lacks the spring that helps it return to its prior position, it won’t be able to revive the former form again. Once depressed, the pedal will just stick to the floor.
Now that you have looked into all the possible causes for sticking the clutch pad to the floor, along with some fixes, you can try it yourself; let us answer some of the common questions you might have regarding the clutch pedal being stuck to the floor.
What Is the Meaning of Dragging Clutch?
The term dragging clutch or clutch drag is used when you can’t shift to a particular gear on your vehicle. As far as the name is concerned, it points out that the clutch is dragging on the assembly and not letting go of the disk completely.
What Do You Need to Do To Unfreeze a Clutch?
To unfreeze a clutch, you need to perform two steps. The first one is to ignite the engine while you are in neutral gear and wait till the engine warms up a bit. After a few minutes, press the clutch pedal. The heat produced from friction may loosen up the clutch, thus unfreezing it.
Is It Safe to Drive the Car With a Broken Clutch Cable?
No, it isn’t recommended to drive a car when its clutch cable is already broken. Though we won’t say that it poses you with any kind of serious harm or risk, we can say out loud that this will cause more damage to the clutch system and some other adjoining components of your vehicle.
Does the Clutch Pedal Stick to the Floor Even After an Oil Change?
No, an oil change has nothing to do with the pedal sticking to the floor. However, if you have recently changed your car’s oil and are experiencing the pedal sticking right after it, the problem-causing agent is likely the clutch itself.
