on my 92 f250 i was stopping at a stop sign and my clutch pedal went clear to the floor and didnt work... it has a hydraulic clutch and there is no line broke and the resurvour is full .... what is wrong ??? any suggestions???

 

If your clutch pedal is "dead" then I would check the linkage between the pedal and the clutch master cylinder. When you press the pedal, the force is transferred through a linkage to a piston in the master cylinder which pushes the fluid through a line/hose to the piston in the slave cylinder which pushes a plunger to mechanically actuate the clutch. So, it could be a broken or disconnected linkage, a blown seal on the piston in the master cylinder or slave cylinder, or an internal problem with your clutch. If it is the seal on the piston in the slave cylinder you will have fluid leaking out where the plunger comes out.
