I have a 2002 toyota hiace diesel van it has a slave/master cylinder, i changed it bleed the clutch but it makes a clicking sound when i push the clutch pedal in what should i do

Since there is very little fluid movement when you press in on the master cylinder and the fluid travels down, it can be very annoying to try to get a clutch system to bleed. The best luck I have ever had was to push in the clutch pedal with my right leg until it got tired and then switch to my left. When it was tired i'd switch back to my right. If you press the pedal all the way down about 100 times, it usually has enough pressure to operate.

Yes they are the same . Check that the master cylinder is operational as a slipping clutch can be a blocked compensating port not allowing the fluid to drain back to the reservoir and holding the pressure on the clutch release.

From you description I would suggest a change of the master cylinder

Check that the slave cylinder is fully releasing the clutch (push the clutch fork and shaft all the away back into slave cyl.. If ok replace the clutch assy.

I have a 1995 hiace bus where do I bleed it from

the most likely reason is either the clutch master cyl. needs to be replaced.or the.slave cyl. its mounted down on the transmation under the hood find the resivore for the clutch. check the fluid level.if its low , fill it back up , and look for signs of a leak
you will probally have to bleed out all of the air from the system.its done almost the same way as bleeding the brakes. Good Luck.

on the transmission there is a slave cylinder that works like a brake cylinder, when you apply pressure to the clutch pedal a rod inside the vehicle under the dash pushes into a clutch master cylinder, (almost like a brake master cylinder without the reservoir, as the clutch master cylinder works off the brake master cylinders reservoir) the plunger in the clutch master cylinder applies fluid pressure to the slave cylinder,(located down on the trans near the clutch fork assembly) which projects a piston rod into the clutch fork dis-engaging the clutch. To bleed the clutch slave cylinder locate the bleeder screw on the slave cylinder,break loose so it loosens and tightens easily. Check fluid in brake master cylinder reservoir,fill if needed, while bleeder on the slave cyl is closed have a helper push clutch pedal to floor and back 7-8 times, (At first the clutch might stay at the floor, just pull it up by hand or foot and continue) after several pumps with no rest time push pedal to the floor and hold down with foot pressure, at this time loosen the bleeder on slave untill fluid leaks out, watch for air bubbles, close bleeder and repeat untill there is no sign of air bubbles, (make sure to check fluid in the brake master cylinder and keep fill as needed, do not let fluid get less than 1/2 empty as it might **** air and you will have to start over) If this does not bring clutch to operate then you need to check if slave cylinder is reachig its full extension of push rod or not. If it is not then you will have to replace the clutch master cyl or the clutch slave cyl or both as seals are bad and wont hold pressure. Or you need to inspect the clutch fork,the throw-out bearing, or the pressure plate fingers and clutch plate for failure or broken bent parts. I hope it turns out to be a easy fix on that clutching thing.

did you bleed the system?? you must bleed the system from the clutch slave. if this has been done, I need more info!! How does the clutch pedal feel, is the clutch slave engaging at all??

The bleed screw should be located on the slave cylinder, near the clutch area, but the problem sounds like no fluid in the system caused by a blown piston cup in either the clutch master cylinder or the slave cylinder, or a hole in the connecting fluid line. Look for fluid leaks from one end to the other. Hope this helps!

Replace master cylinder
