Try using 2 people , get the person inside to press the pedal and you undo the bleed valve a little, tighten the valve and get them to release the pedal (or pull it up if it is a little stiff) keep going untill no more air is expelled.

New clutch installed. No pedal, stays on floor unless I bring it back up with my hand. No resistance.


`Did it bleed, did fluid come out in a steady stream? Isn't there a spring to bring the pedal off the floor?
Check the linkage of the pedal to rod to the clutch master cylinder, make sure that is all together. Any chance the master has an internal leak and won't build hydraulic pressure down at the slave? If you get it bled, then watch the slave operation while someone works the clutch pedal. The piston on the slave should extend and push the clutch fork enough to disengage the clutch.

I have a 93 nissan 300zx non turbo. The clutch is still slipping when car is hot. I've replaced clutch and pressure plate, slave cylinder and clutch master cylinder. What else could it be??


Are you using authentic nissan parts ? If you are, not that is where your problem might exist .Have you checked the clutch pedal to ensure it is not sticking or binding somewhere ? If the master cylinder piston is sticking you may experience this problem .

1990 300 zx installed slave and master clutch cylinders,bleaded,and still clutch wont work


The master is bad,or the clutch is worn out,If the clutch will not disengage so you can move the shifter ,then the master for the clutch is bad,but if it just does not pull the vehicle,then the clutch needs replacing.

Repair master clutch cylinder on a 92 300zx


You should be able to buy a rebuild kit for the cylinder, I would rebuild the slave and master. just take it off, take the snap ring off and remove the piston, make a note of which direction its facing, the new one may come with a piston with the seal aready installed.The cup will have the flare facing forward. Just put the new seal on/ or piston in and reseat the snap ring. The slave is just as easy. then you want to bleed all the air out. Fill master cylinder and open the slave bleeder screw, just let fluid come out until all the air bubbles quit. that should bleed it. If the pedal dosent feel right, you may need to have another person depress the pedal and then open the bleeder.

300Zx will not shift out of 5th gear


is there any pedal pressure when you step on the clutch? I had a similiar problem with my 91 300zx tt....it was stuck in third gear, no pedal pressure on the clutch whatsoever....i had cracked the pivot ball and the clutch slave 'popped out'. i had to pull the trans to fx the problem because i could not reattach the clutch fork onto the release bearing with the trans in the vehicle....you need to bleed the system...gravity bleed the slave until there are no air bubbles. make sure you top off the clutch master cylinder in the process.....then bleed the clutch operating cylinder.....it is in the passenger front hood near the power steering resivoir....top off the clutch master cylinder again. i hope this helps.

The clutch on my car stuck to the floor. I check the reservoir was completely empty. I have a feeling the slave cylinder is filled with air. I'll need to get the schematics to see how to bleed the clutch.


Bleeding the clutch is similar to bleeding brakes. You'd pump the clutch pedal several times to get the pressure up, and then open the bleeder on the slave cylinder (mounted down on the transmission). Repeat and add fluid as needed until no air comes out.

Two things - first off, some cars have more than one bleed point (the Nissan 300ZX is one of those), so be sure there is only the slave cylinder to bleed. Second, if it went right to the floor, something failed - either the slave cylinder or the master cylinder. Changing the slave is relatively easy - usually two bolts and it comes off, you put on a new one, and bleed it as described above. Often the slave cylinder is less than $30, so it's worth it to try changing it if you can't get the pedal to come back off the floor on its own. A clutch master is significantly more expensive and more difficult to change, so start cheap and easy and replace the slave cylinder if you can't pump the pedal to get pressure built up for a bleed.

1992 Nissan Pathfinder SE: replace master/slave clutch cylinders


Removing and replacing is straight forward mechanic work.Here is a gotcha that very few manuals will tell you,but years of experience will teach you.Go ahead and install the clutch slave cylinder on the bellhousing of the trans.The clutch master cylinder needs to be "bench bled" so that as much air as possible is gone from the master cylinder before installed on the vehicle.This requires a helper.Take master cyl. to a bench and set it down while holding the assembly in your hands.Fill the reeservoir with brake fluid.I wear latex or nitrile gloves while i work to keep my hands clean.This helps in sealing off the output fluid port during this procedure.Have your assistant take a phillips head screwdriver and push the piston in,on the master cyl and hold it in the depressed position.Some fluid and air will shoot out the output port.Now take your latex glove clad finger,and press it firmly over the fluid output hole.Now release the screwdriver.Remove finger from hole,and stroke the piston in with the screwdriver and hold it at it's depressed position.Place finger over the hole.Add fluid to the reservoir.Keep repeating until only solid fluid exits the output hole.This is bench bleeding.Now install into vehicle being careful to not get brake fluid on the paint.After installing,on the clutch master cylinder rod...there is a jam nut,either 12 mm or 14 mm.Loosen this nut and back it off.Now,the threaded rod can be spun in,or out,making the rod shorter or longer.this is how you adjust the clutch pedal engagement point,after installation.Back to the clutch master and slave,they obviously need to be bled after installation,with the bleeder valve down on the slave cylinder.Good luck.
