Clutch pedal to the floor?

[Disciple]

I have a stock 99 F350 SD 2WD, 7.3 PSD with a 121,000. I was going to Homedepot this afternoon and in the parking lot I pushed the pedal down and couldn't shift. I let up on the pedal and it stuck to the floor. I pull the pedal up with my foot and as I pushed it back down I could hear a vacuum noise and it seem to get sucked to the floor after a certain point. I don't seem to be having any problems with the clutch kit. The truck don't slip, shake, shudder, or smell like the clutch is slipping. So I am thinking it may be a master cyl. or the slave but I would really like to try and narrow it down to save some money. Would anyone have a suggestion? Thanks

Sounds like the slave cyl to me. Just don't take it to Ford to fix. They charge an arm, leg, and first born son.

I 2nd the slave Dont cut the formed hard plastic line to remove it (i did it once) There is a roll pin that you can push out on the housing and the tube will slide right out

Could be either. Have a look at both for leaks.

[Disciple]

Nothing seems to be leaking.

How's the fluid reservoir level?

[Disciple]

I thought it was low when it first happened but it really wasn't. So to answer your question it 's not low at all

[dbkerley]

Probably the master then.

I have heard that they are a bear to bleed or should I say remove all the air. which leads me to my next question. How do I go about bleeding the system? I do have a hand pump bleeding tool.

Not that bad actually. You can get a pre bled master/slave assembly from the dealer. If you can locate either the master or slave cylinder on their own, you can replace it and fill the system as best you can. Then there is a way to expel the extra air when the system is installed. I can PM you instructions.
