I replaced the clutch about 6 months ago and now my clutch pedal is going to the floor and stays there. Seems to have no hydraulic pressure. Replaced the clutch master cylinder and the slave cylinder. I have a 2004 camry 4 cylinder 5 speed. Any suggestions?

The cluthc master cylinder was especially hard to change, is it possible that I broke something or did not bleed properly?

 

Did you bleed the master cylinder before connecting to and bleeding the line?

 

I am concerned when you say 'especially hard to change.'
I replaced a master cylinder on a Fiero once and I did not have things quite lined up right and when the pedal was pushed in, a big gouge was carved into the walls of the cylinder. My clutch pedal would not return as it should have after my error.
Also, be sure to check all pedal return springs under the dash, even though the hydraulic pressure should be enough to return the pedal to the upright position.
