* Low clutch fluid. If the clutch fluid is low, the clutch will not be able to engage properly and the pedal will go to the floor. Check the clutch fluid reservoir and add fluid if necessary.
* Air in the clutch line. Air in the clutch line can cause the clutch pedal to go to the floor. This can be caused by a leak in the clutch line or by a bad clutch master cylinder.
* Worn clutch disc. A worn clutch disc can cause the clutch to slip and the pedal will go to the floor.
* Bad clutch pressure plate. A bad clutch pressure plate can also cause the clutch to slip and the pedal will go to the floor.
If you are experiencing any of these symptoms, it is important to have your Miata inspected by a qualified mechanic to determine the cause and have it repaired.
