Ok guys so a few days ago my clutch lost all pressure so i figured it might be the slave cylinder because i had a problem bleeding it when i put a stage 3 clutch in about a year ago but a few days ago it lost all pressure in the peddle so replaced slave cylinder and after bleeding it it got really stiff so stiff it takes both feet to push it to the floor and it want go in gear does anyone have a i deal what this could be.

 

It would help to know more specifics like model year, power you're putting down, how car is used, etc. But that said...

I'd suspect you have a clutch in which the stock hydraulics can't keep up with and something in that portion of the system has finally failed.

You will likely need to go to more performance oriented hydraulic system such as Tilton or Wilwood that are more resilient to the increased pressure needed to actuate a high sprung PP.

OR....

Bent clutch fork or pivot due to the high spring load caused by, again, such a high sprung clutch plate.

 

You may have to peddle some parts to pay for repairs

 

Ok so like i said before i got to use both leg to push it all the way to the floor or to even move the pedal i bled it about 5 to 6 times its a 2003 350z grand touring also if im not pushing on this clutch pedal after i build pressure up if i let it set for even 1 second it loses all pressure

 

The Grand Touring trim wasn't available until 2006.

You still using the factory master cylinder?

 

just take it to a shop.... jeebus

 

This is a shot in the dark, but if there's no fluid exchange from the master cylinder to the slave cylinder, that could cause a hard clutch pedal. Are you sure that you properly connected the master cylinder to your new slave cylinder?..
