5spd clutch...

[silv3r0ne]

i have a 5spd tranny on my 280z. when i bought the car, the pedal for the clutch would hit the floorboard if you pressed it down. so i thought that filling fluid and bleeding the clutch would fix the problem. after cleaning everything out, i filled fluid in the clutch resivoir (spelld that wrong) and went ahead and started bleeding the clutch. after several attempts, it didnt seem like anything got better. while under the car, i was looking at the clutch as my buddy was pressing the pedal, it seems like its missing something(maybe a spring or sometihng)...could that be my problem??? as always, any and ALL insight/help would be greatly appreciated. thanks

Are you leaking fluid anywhere? Either inside the car behind the clucth pedal or uncerneath the car at the slave cylinder? Your master or slave may need to be rebuilt or replaced. If I remeber correctly, if the master is good and the slave is bad, the slave will leak fluid when you depress the pedal. If the mastter is bad and the slave is good you won't get the leak at the slave but in either case you pedal will go to the floor. The later cars don't have a spring on the slave cylinder.

I don't know why my original reply didn't show on the front page. Some kind of glitch I guess.

i filled the fluid up last monday. car.s been sitting in my garage the whole time and till today, i see no leaks under the car and the fluid level in the master cylinder is still where i left it at. when i press the clutch pedal down, i feel NO pressure at all. ZERO resistence... ...help me...

If you're using your back icon to get back to the home page, your response won't be there, because that is the page your computer has stored in it's cache. If I go back that way, I hit the refresh button and all is well with the world.

Sounds like either the master cylinder needs to be replaced, or you have air trapped in the master cylinder.

How low was the fluid level before you re-filled it? Does the master cylinder reservoir have a lot of black "crud" in the bottom of the reservoir? If so , did you remove the screen (small needle nose will get it out)and clean it before you filled it with fluid?

There is no provision to bleed the master cylinders independantly of the rest of the system, so this is how I do it. Break loose the bleeder on the slave cylinder, fit a plastic hose onto the bleeder and put it in a bottle of some type with a little fluid in the bottom with the end of the hose in the fluid. With your fingers, lightly close the bleeder so that it is barely open and then depress the clutch pedal 4-6 times. By opening the bleeder only slightly like this will put a little "backpressure" in the system and help force any air out of the master cylinder. If you open the bleeder on the slave it will bleed by gravity, but it won't force out any trapped air.

Make sure the master cylinder reservoir stays at least half full during this process. If you still have no clutch after this 20 minute job, you need a new master cylinder.

I know that but that's not what I did. I had actually shut down the computer and came back later. When I clicked on the thread my reply showed but it didn't show on the front page. Not until the second reply.
