You should not attempt to replace the clutch yourself unless you have considerable mechanical skills. In this case, the problem is most likely that the spring holding the clutch pedal in place is broken.
if its hydraulic there could be air in your line. bleed your clutch and refill.
A major indicator would be when you push the clutch in, you can't shift your transmission. Another one would be when you push the clutch pedal, it just goes straight to the floor with no resistance, or it doesn't push in at all.
The clutch IS supposed to go to the floor. Do you mean why doesn't it release the transmission from the engine. It probably needs to have air bled from the master cylinder and the slave cylinder.
I had same problem so I changed clutch, no diference. found the plate the clutch pedal conects to had pulled away from bulkhead. rewelded to bulkhead and clutch was fine.
It sounds like the clutch master cylinder or slave cylinder has gone bad.These are not that expensive to replace.
obviously you have a clutch line or slave cylinder leak.
That would be a standard transmission.
Clutch slave cylinder is leaking fluid or the connector rod or cable from the clutch pedal is disconnected or broken. Depends on the make and model of the vehicle to know the exact setup of your clutch.
The clutch Throw Out Bearing is going bad.
i think the clutch pedal should be the same as a 94 escort where it would be around 2.5 inches wide and 2 inches tall
