If the fluid level drops after the bleeder screw has been tightened, you may have a leak somewhere in the system. For instance, in a clutch line, master cylinder, or slave cylinder. Even if there is a leak the size of a pinhole, you will need to address the issue.
How does the master cylinder work in a clutch?
The clutch master cylinder works as a container for the brake fluid that connects it to the slave cylinder through the hoses. Every time you press the clutch, it makes the fluid flow from master to the slave cylinder, and the gear changing mechanism happens. Let’s see how to bleed the clutch:
How do you close the bleed screw on a Jeep Cherokee?
Close the bleed screw. With your friend pressing the clutch pedal to the floor, use the open ended wrench to turn the bleed screw clockwise to tighten it again. This will once again seal the hydraulic clutch system, preventing air from getting sucked back into the system through the bleed screw.
How do you bleed air from a slave cylinder?
Adding the new parts introduces air into the system, which creates a soft or non-existent clutch action when you press the pedal. To bleed air from the hydraulic clutch system, you must release air from the slave cylinder.

How is the brake fluid connected to the clutch?
It is connected to the clutch slave cylinder through hoses. When you push the clutch pedal, brake fluid flows from the clutch master cylinder to the slave cylinder, applying the pressure necessary to move (engage) the clutch and this in turn changes the gears on your manual transmission.
Open the bleeder valve – Use a line wrench to open the bleeder valve to the slave cylinder. Attach the vacuum pump – If you do not have a friend handy, or if you choose to use a hand operated vacuum pump, attach the vacuum pump to the slave cylinder.
Why does clutch line bleed from master to slave?
Everyone always bleeds brakes and clutches downwards from the master to the slave including using suction with a vacuum pump, but I cant see any reason your couldnt do it upstream with pressure instead of a vacuum. After all, you just need to get the air out, thats all. Will remember this trick 😉 So anyway, Ive had a success.
Where is the bleeder valve on a clutch fork?
If you know where your clutch fork is on the transmission, the clutch slave cylinder should be attached to it. Once you’ve found the slave cylinder, locate its bleeder valve. This should look like a small nut on the end which usually has a diameter of about 8mm. The nut is often covered by a rubber nipple to keep dirt and debris out.
If the fluid level drops after the bleeder screw has been tightened, you may have a leak somewhere in the system. For instance, in a clutch line, master cylinder, or slave cylinder. Even if there is a leak the size of a pinhole, you will need to address the issue.
Does the clutch need to be Bleed?
Most hydraulic clutch systems have their own dedicated master cylinder; however, some vehicles use one master cylinder for both the brake system and the clutch system. Any time you open the hydraulic system you will need to bleed it to remove air pockets. Air pockets prevent the hydraulic system from functioning properly.
How do you Bleed a clutch system?
The easiest way to bleed the clutch is to use a vacuum pump to pull the fluid and air out of the system while keeping the clutch fluid reservoir topped off. Continue pumping fluid from the bleeder valve until you no longer see air bubbles in the fluid.
Will brake fluid ruin a clutch?
If your clutch master cylinder leaks out brake fluid, you won’t have enough pressure to engage the clutch, and your vehicle will not be able to change gears. If the brake fluid in your clutch system becomes contaminated, it can cause severe damage to the slave cylinder and clutch master cylinder.

How often do you pump the clutch pedal?
Tell him to pump the clutch pedal 10 to 15 times, and after that, tell them to hold the clutch pedal completely down. While the clutch pedal is still down, it is time to open the bleeder using the line wrench. This would make the fluid exiting the slave cylinder.
Why is it hard to bleed the clutch system?
Open beer and give up. “I think the biggest reason it is so hard to bleed the clutch system is because the bleeder valve is lower than the incoming fluid line. Gravity bleeding will work to clear the clutch line of air, but there will be a bubble left in the slave cylinder.
How can I test The Bleeder on my Clutch?
Test the bleeder – While the clutch pedal is held to the floor, use your line wrench and open the bleeder. Observe the air bubbles and brake fluid exiting the slave cylinder.
When do you close the bleeder valve on a clutch?
Close the bleeder valve when you see no more air bubbles in the fluid; release the clutch pedal as well. You would need to have another person as this operation can’t be done alone. Finally, it is time to test the clutch once the slave cylinder has been bled.
When to close bleeder valve on clutch pedal?

What happens when you press the clutch pedal?
As you press the clutch pedal, the master cylinder forces hydraulic fluid, in this case brake fluid, down through the line into the slave cylinder. The pressure of this fluid will cause the slave cylinder to activate, pushing your clutch fork and disengaging your clutch. If there is air in the system, that air bubble can compress.
What causes the clutch fork to disengage?
As you press the clutch pedal, the master cylinder forces hydraulic fluid, in this case brake fluid, down through the line into the slave cylinder. The pressure of this fluid will cause the slave cylinder to activate, pushing your clutch fork and disengaging your clutch.
Why does my car bleed when I open the bleed screw?
Clear hose allows you see the fluid run clear and free from air, but it’s not essential. The release man opens the bleed screw and fluid rushes through the hose to the catch bottle. A dab of grease around the bleed screw threads before opening to bleed prevents air sneaking in when bleeding.
What to do if your clutch pedal has no pressure?
To bleed you hook up a tube on the bleed nipple and submerge it in a cup of fluid, or open the valve as someone pushes the pedal down, closing before the air starts to go back in. Pull the pedal back up and keep repeating. Check the master fluid level every few minutes.
What should I do if my Clutch drops?
