Need help just changed out the master clutch cylinder
(brand new (Aisen brand Japan)) and now there is no pressure when I try to engage the clutch pedal.

Before had my clutch slave cylinder replaced 2-3 months ago.

-had problems with the clutch sticking and having to pull pedal back up with feet.

I had extended the lever for the clutch pedal for first try and no pressure.
Then I tried with the same length as the old master clutch cylinder, still no success.

-clutch fluid level was always filled, had a person do couple cycles with the peddle all the way down, and up then hold it down while I loosened the clutch relief line to drain the air.

-clutch fluid reservoir had lil bubbles going up every once in awhile dunno what that means.

But, still no success. No clue why any help would be appreciated thanks in advance.

put hose on the bleeder screw on the salve cylinder and the other end of the hose submerged in container of brake fluid
that way no air can re-enter the lines

is that why theres no pressure? ooo so the lever length of the clutch master cylinder to connect to clutch pedal doesnt affect it? thanks for response

hold the pedal down, let the brake fluid drain out the bleeder for a bit and catch into a small cup or pan. then after a good hour or so. close the bleeder and release the pedal. see if u got any pressure. thats one way to do it.

o there was no fluid going out of the bleeder after I filled the reservoir back up and tried pumping the pedal

its gonna take a bit of work. thats all i can say. just keep working it till fluid comes out the slave cylinder.

also had this issue. i first replaced the slave cylinder, but no pressure was being built up. Master cylinder had finally failed.

Got a new master cylinder and everything worked like a charm, once I bled the system. Its easier to have someone with you to pump the clutch as your down there handling the bleeder valve. gl

its smart to replace both if one goes bad
you do not have to but its smart to
get someone to work te peddle while you or him works the bleeder screw but make sure you put that hose on the end and the other end in brake fluid submerged otherwise your wasting your time basically

apparently your suppose to tighten the bleed screw with a wrench, and *hand tight* just wouldnt do the trick. also screw from clutch to master cylinder was hand tight.

thanks for responses, I also used the tube in the bottle and it helped with bleeding the system
