"Check if clutch master cylinder or slave cylinder is bad. The master or slave cylinder can fail due to an internal or external seal leak. The most common seems to be external seal leakage. Inspect the clutch master cylinder and slave cylinder for leakage and rebuild or replace if leaking. One check you can perform on the master cylinder is to depress the clutch pedal while someone watches the brake fluid reservoir level. If the level rises while the clutch pedal is being depressed, the clutch master cyl

Hello, thanks for your question. You could watch the clutch fluid as it mentions in the test, but this really doesn’t tell you much. Most of the time this is caused by a bad clutch master cylinder. If the fluid level is low the first thing to do would be to locate the leak. If the fluid is full then I watch to see that he clutch slave is moving when the clutch is pressed. If it is and if it is releasing but the pedal stays down then that is another reason to change the clutch master. If the clutch slave and fork are not releasing then it may have an internal clutch failure. If you would like help getting this inspected or repaired, consider YourMechanic, as a certified mechanic can come to your home or office to perform the inspection and make or suggest any repairs needed.

There are typically a few different possibilities for why a clutch pedal will stay on the floor. It could be a failed clutch master cylinder, slave cylinder, failed fluid line, or the clutch has failed.
The clutch pedal sticking to the floor is usually an indication of a hydraulic problem in the clutch system, typically a system that nees bleeding. The clutch hydraulic system does not use engine vacuum. You should also check the adjustment of the overcenter spring above the clutch pedal.
Sudden failure is most often caused by a broken or loose clutch cable, linkable or a failed hydraulic master/slave cylinder. There can also be leaks in the hydraulic line or even the disc could be contaminated with something like dirt or debris.
In most loose clutch cases with a hydraulic system, it is a probably an issue with the master cylinder. Internal or external damage to the cylinder can cause the hydraulic fluid to leak out and it simply will not perform properly once the fluid is too low. Sometimes, it is simply a worn seal that needs to be replaced.
Clutch Pedal Remains Stuck to the Floor. Clutch Pedal Feels Loose or Spongey. Clutch Pedal is Hard to Engage. Transmission Makes A Grinding, Whirling or Chirping Noise in Neutral.
Air as cause of malfunction
As far as the hydraulic clutch is concerned, the following symptoms may occur: Change of the pedal travel. Difficulties in disengaging the clutch. Imprecise pedal feel.
Although some hydraulic clutches can be adjusted, many are self-adjusting. Check in your car handbook or service manual. If slip occurs on a self-adjusting clutch, the clutch has to be overhauled. If drag occurs, the hydraulics may be at fault (See Checking and removing a clutch master cylinder ).
If your clutch pedal feels soft or `spongy` at any point as you press it to the floor, it`s a sign your clutch fluid is low. That spongy, inconsistent feeling is due to air in the clutch line from the master cylinder to the slave cylinder.
Broken springs, overheating, and even a worn-out clutch disc can cause problems with the clutch pressure plate.
A clutch that sticks can cause grinding noises or can keep your vehicle from going into gear while a clutch pedal that is stuck to the floor renders your vehicle undriveable. If either of these situations happens to you, a trip to your mechanic is in order.
If there is air in the system, you do not get enough pressure and the clutch is not able to fully engage. Bleeding the clutch is a process in which you remove all the fluid currently in the system, getting out all the liquid and air, and replacing it with purely liquid.
Yes master cylinders can fail without leakage, the clutch master cylinder has a piston inside and there are separate channels for hi-pressure line and return(low pressure) line and their location in the cylinder differs for manufacturers.
These are the most common causes of lowered clutch pedal position you should know about: Improper clutch repair. Hydraulic fluid leaks. Air bubbles in the hydraulic fluid lines.

My clutch pedal goes to the floor and doesn’t return
ANSWER : Check clutch pedal assembly bracket for breakage or mis-position. It’s also possible that the pressure plate is to blame. However, before diagnosing that you do have to confirm the hydraulics work. Even though the master and slave are "new", these may be rebuilt parts. If not properly rebuilt, the master could easily have an internal leak which would explain your circumstance. If, in your application, you are able to get some direct indication that the lever off of the pressure plate is in the return position, and you cannot see any fluid leakage under any of the boots that seal the hydraulics, and you are certain that you have bled and re-bled and there can’t possibly be any trapped air, I would suggest trying a different master and slave because they could be defective. Alternatively, a certified mechanic could be dispatched by YourMechanic to take a first hand look at this. If you desire to go that route, please request a clutch inspection and the responding mechanic will get this resolved for you.

Clutch pedal goes to floor when pressed
ANSWER : With the symptoms you have described, the most likely cause is a leak in the clutch hydraulic system. If there is a leak on the system it causes air to enter. Since air is not able to be compressed the clutch pedal remains stuck to the floor when it is pressed down. With everything going on with this car, it is unsafe to be driven until the clutch has been repaired. A qualified technician, like one from YourMechanic, will be able to confirm the cause of your clutch issue and perform the needed repairs to get you back on the road.

Clutch pedal stays to floor. Replaced master cylinder. Clutch push rod broke. Also do I need to change slave cylinder
ANSWER : If you have an issue with your clutch pedal going to the floor, the slave cylinder is normally the cause of this circumstance.
Also, if the push rod has been broken the first step would be to track down a new one because that push rod is a very necessary part of the clutch pedal system.
Once a new push rod has been located and installed, I would recommend having a new slave cylinder installed as well.
If you are in doubt about this repair, I would recommend having it performed by a qualified professional, such as one from YourMechanic. One of our mobile technicians will be able to come to your home to diagnose the issue with your clutch pedal and replace your clutch slave cylinder as necessary.

My clutch pedal is stuck to the floor. A while back I started hearing noise in my clutch when I pressed it. The car drive fine, th
ANSWER : Your vehicle uses a hydraulically operated clutch system. The first thing to do is check the fluid level in the master cylinder and check for leaks although leaks at the slave cylinder might not be apparent. Internal seal failures can cause the same problem that one might experience (i.e., no clutch operation) with visible leaks and a low fluid level. The noise may be due to a failed clutch release bearing. Due to the noise and the misoperation, if the slave cylinder turns out to be faulty, you will probably need a new clutch as well as hydraulic components. The cause of the fault that you are reporting can be pinpointed if you request a hydraulic clutch system diagnostic. If you request that diagnostic, the responding certified mechanic will get this diagnosed and let you know exactly what must be done. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I have no clutch it goes to the floor and I cannot find the slave master cylinder for the clutch master cylinder please send pics
ANSWER : The reservoir supplying the fluid to both cylinders is the brake master cylinder reservoir. However, adequate fluid there means nothing as a diagnostic. The clutch slave and/or master cylinder could be leaking internally (no visible external leak) or there could be air in the clutch hydraulic system that will have to be bled out. There are other mechanical causes of the clutch pedal going to the floor but in your circumstances that hydraulic circuit should be looked at first. If you desire a diagnostic, and repair of this issue, right at your location, please request a clutch system inspection. If you request that inspection, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Why does my clutch pedal sink to the floor and dosent come back up?
ANSWER : Hi – there are 2 main causes for the clutch going all the way to the floor. First – check that the return spring on the clutch pedal is in place. Second – I see you bled the system – bleed the system again. This is how I would do it – use a short length of hose connected to the bleeder screw, run that hose into a cup half full with recommended fluid…fill the reservoir, then have one person pump the pedal while the other opens the bleeder screw and watches until NO BUBBLES come out (and makes sure the reservoir doesn’t run dry). Then close the screw fill the reservoir to the mark, and test her out. If you would consider, YourMechanic can send a certified technician to you and assist you in troubleshooting this clutch issue.

Clutch not working after replacing slave cylinder and master cylinder
ANSWER : Hello. We will be happy to help you with your vehicle. It sounds like you have a problem with your throw out bearing. You would likely need to drop the transmission once again and check that the installation of the throwout bearing is proper. You may also try to peel back the boot around the slave cylinder to see inside of the transmission. By doing so you may be able to see possible damages on the throwout bearing. It will be a great idea to use a stethoscope before you take the vehicle back apart to help pinpoint exactly what portion of the transmission coming from. Another very important thing that you should check are your axle’s, make sure they are seated correctly inside of the transmission.
