First pump the clutch 4-5 times quickly. then siphon out fluid in top container, replace with new fluid of correct class. Slave cylinder at the transmission should have a bleed port or screw. open it and bleed until clean fluid comes out, usually refilling the top 3-4 times. Do not let the top res. go empty! If it still does not disengage the clutch correctly you may need to replace the master clutch cylinder or the slave on the transmission.

SOURCE: 1996 Ford Ranger XLT Clutch Bleeding

The problem is up at the Master Cyl............It comes ou of the firewall and points DOWN at about a 45 deg angle.....The reservoir is remote and the hose is set to the lowest point of the cyl...........The tube TO the slave is 180 deg around facing bottom...........
Take the master cly OFF the firewall.......tilt it so that both inlet and outlet are the HIGHEST point of the cyl........Gravity bleed or vacula the slave.........then reinstall the master
I know it sounds like a lot of work but it's the easiest way to clear the air out of Ranger/Explorer hydraulics

How do i bleed clutch on fiat dublo


Clutch systems bleed just like brakes, if you have an external leak at the clutch master cylinder, then bleeding will be difficult, it should be replaced. I use a two person bleeding system, I fill the master, crack the bleeder screw open and have my 2nd push the clutch down and hold it, then I close the bleeder and tell my 2nd to release the pedal, repeat until no air is present.

I have an 84 Honda shadow vt700. The clutch was working but would slip when hot it would get to where I could release clutch with bike in 1st gear and nothing would happen! It would just continue to idle!...


Bleeding the hydraulics will not improve the friction drive of the clutch in any way,your clutch drive plate is worn out and needs replacing. To bleed the hydraulic line ,make sure that the master cylinder is fully topped up,pump clutch lever several times then tie ,using a zip tie the clutch lever all the way to the handle bar,gently open the bleed screw and await fluid to start dripping from the bleed screw, this may take an hour or two but it will eventually bleed itself,once 25% of the fluid has discharged from the the master cylinder tighten up the bleed screw and this is the easiest DIY way of bleeding a hydraulic system, without a pressure bleeder.

I recommend bleeding the clutch using instructions pasted from autozone.com below. As for the engine light, please get the computer scanned and send us the diagnostic trouble code.
Hydraulic System Bleeding NOTE
It is necessary to bleed the clutch hydraulic release system if the system has lost an excessive amount of fluid and has allowed air into the circuit. Air in the system typically results in a spongy pedal feel, and/or improper clutch release. If air cannot be removed from the system using this procedure, it is necessary to replace both the clutch master cylinder and slave cylinder assemblies.

Except Turbocharged Models
  1. From driver's seat, actuate clutch pedal 60-100 times. Verify clutch operation/pedal feel. If pedal still feels spongy, or clutch does not fully disengage, excessive air is still trapped within the system. Perform the following procedure:
  2. Verify fluid level in clutch master cylinder reservoir. Top off with DOT 3 brake fluid as necessary.
  3. Raise and safely support the vehicle.
  4. Remove clutch slave cylinder assembly from the transaxle case, but do not disconnect from the system. Allow the slave cylinder hang, making it the lowest part of the system.
    CAUTION
    While slave cylinder is detached from the transaxle, DO NOT actuate the clutch master cylinder. Damage to the slave cylinder will result.
  5. Depress slave cylinder pushrod until it bottoms and then release. Repeat this at least ten times, forcing trapped air upwards and out of the system.
  6. Re-install slave cylinder into position. Torque slave cylinder to case bolt to 168 inch lbs. (19 Nm).
  7. Carefully lower the vehicle.
  8. Check and adjust clutch master cylinder fluid level. Actuate clutch pedal thirty (30) times. Verify clutch operation/pedal feel. If pedal still feels spongy, or clutch does not fully disengage, air is still trapped within the system. Repeat Step 3 through Step 7 until air is purged. If several attempts at purging air from the system are unsuccessful, replace both the clutch master cylinder and slave cylinder assemblies.
  9. Raise and safely support the vehicle.
  10. Carefully lower the vehicle.
  11. Top off clutch master cylinder fluid level with DOT 3 brake fluid as necessary.
Turbocharged Models

NOTE
Due to the angle and design of the turbo hydraulic system components, gravity and pedal bleeding are less effective and less efficient than the reverse fluid injection method (reverse bleeding). Reverse bleeding is recommended for this system, and requires the use of commercially available injection bleeding equipment.

Alternate Procedure (Pedal Bleeding)
  1. Remove reservoir cap and inspect fluid level. Top off with DOT 3 Brake Fluid. Actuate clutch pedal briskly at least 50 times. Verify release system function. Repeat. If release system is still inoperative, continue with procedure.
  2. Raise and safely support the vehicle.
  3. Remove clutch bellhousing access cap to expose system bleed screw.
    WARNING
    Use care not to allow fluid to drain into clutch bellhousing. Excessive fluid will be agitated and sprayed around inside the clutch bellhousing by the rotating flywheel, contaminating the flywheel, disc, and pressure plate, resulting in poor clutch engagement.
  4. Using suitable socket/wrench, loosen bleed screw. Immediately install rubber hose to bleed screw to prevent fluid from entering clutch bellhousing. Tighten bleed screw gently with suitable wrench.
  5. Lower vehicle.
  6. Have helper actuate clutch pedal to floor.
  7. Place collection container at end of hose to capture expelled fluid.
  8. Using suitable wrench, break bleeder screw loose and tighten to 62 inch lbs. (7 Nm). Do not over-tighten.
  9. Have helper release pedal, returning it to at-rest position, and then actuate pedal to floor.
  10. Break bleeder screw loose and tighten to 62 inch lbs. (7 Nm). Do not over-tighten.
  11. Repeat procedure as necessary, keeping master cylinder reservoir full during the process, until air bubbles are no longer visible in collection container.
  12. When air bubbles are no longer visible, actuate clutch pedal briskly at least 50 times.
  13. Verify release system function and top off fluid as necessary.
Recommended Procedure (Reverse Bleeding)
  1. Remove reservoir cap and inspect fluid level. Top off with DOT 3 Brake Fluid. Actuate clutch pedal briskly at least 50 times. Verify release system function. Repeat. If release system is still inoperative, continue with procedure.
  2. Remove reservoir from bracket and empty into collection container.
  3. Raise and safely support the vehicle.
  4. Remove clutch bellhousing access cap to expose system bleed screw.
    CAUTION
    Use care not to allow fluid to drain into clutch bellhousing. Excessive fluid will be agitated and sprayed around inside the clutch bellhousing by the rotating flywheel, contaminating the flywheel, disc, and pressure plate, resulting in poor clutch engagement.
  5. Using suitable socket/wrench, loosen bleed screw.


    Fig. Location of the bleed screw for the 2.4L engine
  6. Quickly attach hand operated bleed apparatus to bleed screw. Use care not to over-fill reservoir and spill fluid into engine compartment.
  7. Operate bleed gun sufficiently to expel air upward through circuit and out of master cylinder reservoir. Fill and empty reservoir three times.
  8. Remove bleed apparatus and tighten bleed screw to 62 inch lbs. (7 Nm). Do not over-tighten.
  9. Carefully lower the vehicle.
  10. Top off reservoir with fluid, then return the cap.
  11. Verify system operation. Actuate clutch pedal 50 times. If necessary, repeat procedure until road test confirms that shift issues no longer exist.

How do you bleed the clutch hydraulic system on a 2008 Mustang?


you bleed a hydraulic clutch the same way you bleed a brake system and it uses brake fluid as well.you keep bleeding until there is no more air in the clutch system.there should be a bleeder screw on the clutch slave cylinder that is were you bleed the clutch from.

I press on the clutch and it seems that I have no clutch. I installed a new presure plate and when I was done I went to turn on the truck the clutch pedal does not seem to work the clutch


I don't know if you have hydraulic clutch cylinder but sounds like it may be bypassing or have air in system. Try bleeding system and checking for pressure when pedal is pushed

My clutch is not angaging need to see how can i bleed


Hydraulic Clutch System BLEEDING The clutch system can be bled using a pressure bleeder. Follow the instructions that come with the pressure bleeder for the proper pressure bleeding procedure. The maximum line pressure while pressure bleeding must not exceed 36 psi (248 kPa). NOTE: To bleed a clutch manually requires the assistance of a second person, a section of hose that is compatible with brake fluid (preferably clear) and fits the slave cylinder bleed screw snugly and a container to catch the fluid that is bled through the system. As brake hydraulic fluid easily absorbs moisture, always use fresh fluid when bleeding a hydraulic system.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. To bleed the system perform the following:
    1. Top off the hydraulic fluid reservoir using a fluid that meets the standards of the vehicle's hydraulic system.
    2. Open the clutch slave cylinder bleed screw and press the clutch pedal to the floor and hold the pedal down.
    3. Close the clutch slave cylinder bleed screw.
    4. Release the clutch pedal.
    5. Check the hydraulic fluid level and top off as necessary.
  3. Repeat the above steps until the discharged fluid is clean and no air bubbles appear during the bleeding process.

Clutch pedal stays 2 the floor on a hydralic clutch system on a 2000 camaro v8. clutch master cylinder is new also slave cylinder and clutch and pressure plate


Did you bleed the system? When you replace the the master and/or slave cylinder you have to bleed the system just as you would with brakes. There is a bleed screw on the slave cylinder. Open the bleed screw, have a helper depress and hold the clutch pedal down.Tighten the bleed screw, then release clutch. Repeat this procedure until you have removed all air from the system and the clutch pedal is firm. Keep an eye on the fluid level to avoid sucking air into the system. If you have done this, remember there is a possibility that the master or slave cylinder is defective.
