If you depress your clutch pedal and it falls to the floor, chances are that your clutch cable has snapped. For a mechanically actuated clutch (as many are these days), this is a common failure if given enough time or traveled enough miles. Another reason for clutch cable failure is if the driver "rides the clutch" too much. This happens very easily, but is a very easy to correct, and is when the driver rests their foot on the clutch pedal so slightly that it never fully engages with the flywheel. Everything would appear normal, but the clutch disc will get worn quite quickly and the cable will be under tension at all times. Plus, the release bearing will get eaten up by the pressure plate. So if you or a driver you know "rides the clutch", just make sure that the left foot is resting on the floor when it's not being used... simple.
Early standard transmissions employed a series of rods and Z-bars (bell cranks) to actuate the clutch fork. Sometimes, it wasn't even a clutch fork that released the clutch but was a shaft or long bar. Either way, clutch rods would eventually become loose at their connecting points and make shifting difficult. Clutch cables
were first used on motorcycles, but crossed over to automobiles as they needed replacing less frequently. They are a type of Bowden cable that utilizes a braided steel cable wrapped in a rubber or nylon sheath. One end connects to the clutch pedal via either a ball, loop, or fork, and a bracket on the sheath is fastened or bolted to a fixed point on the firewall or bulkhead. The other end is connected to the clutch fork. When the pedal is depressed it pulls the floating clutch cable through the sheath which then pulls the clutch fork. That pushes the release bearing into the pressure plate and the disc is released.
Replacing your clutch cable is not a difficult task. Simply remove it from the clutch pedal, disconnect the fixed portion from the bulkhead, and pull it through the firewall or floor pan. Then disconnect it from the fork on the transmission. You can now replace the new clutch cable the same way, but in reverse.
