Replaced clutch mastercylinder clutch pedal is hard will not push down


Can you see the clutch slave cyl?
Is it extended fully?
Is this condition after you bled the system?
Try opening the bleeder on the slave cyl in case you have full pressure in the system right now.Also make sure the new master cyl rod from the clutch pedal allows the master cyl to return fully to it's retracted position or the pressure will build up an lock the pedal as yours is.
You want a little play in the clutch pedal rod to master cyl.

Clutch pedal sinks to floor


Unless you have bled the slave cylinder properly there will still be air in it. However I think the problem is in the clutch master cylinder ---piston rubbers leaking fluid back to reservoir. Replace the m/cyl with new item and bleed out correctly.

Clutch suddenly has no resistance and car won't shift gears. Fluids were low, have put fluid in the reservoir but still doesn't work. How do you bleed a clutch line?


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.

Clutch pedal goes to floor no preasure filled and bled slave cyl same result


Hi:
If you have bled the system, you are down to either having a bad clutch master cylinder, or a bad clutch slave cylinder. You could eliminate the slave cylinder by removing the line and capping it off, and if you have a firm pressure on the clutch pedal ( don;'t try to push it down, just check for pressure!) then your slave cylinder is bad. If you cap off the line, and bleed the system, and the pedal still has no pressure, then your clutch master cylinder is bad!

Clutch pedal stays on floor when released


check the helper spring on the clutch pedal. You'll have to get down in the driver's footwell and using a flashlight look at the mechanism while you push the pedal down (and pull up). If the spring isn't missing or broken and everything looks okay, then change the clutch master cylinder. The piston in the cylinder is probably binding due to corrosion in the bore. I have an 1986 and had the same problem. Changing the clutch master cylinder fixed it.

These systems are a pain to get the air out of. Have an assistang push in on the pedal and push back on the slave cyl. and crack bleeder valve at the same time. Step on the clutch pedal slowly when doing this.
