My clutch pedal will stay pressed to the floor after I push it in. I can still drive with it yet I know it's not good at all for it. I have the Haynes book and it said I may not have fluid in the master cylinder or it may have to be replaced. I really can't afford to replace it yet I know I can't afford not too.

I've got my ideas on what to do about it, yet a second opinion never hurts.

well its pretty easy to check if it has fluid in it / is working. Maybe you could try bleeding it?
