QuestionQUESTION: I think the clutch cable on my 1990 Miata broke. Can anyone tell me how to replace it, or at least get me started on the process? It doesn't say in the Haynes Manual. Thanks a bunch. Cindy Lou
ANSWER: The Miata has a hydraulically activated clutch, no cables. Clutch problems are either; No pedal or a weak pedal which normally indicates a clutch hydraulic failure. Or, a lack of engagement or slippage upon acceleration.
The prior condition requires a new master cylinder and a new slave cylinder to be installed with new fluid of course. (a hose or line failure is seldom a problem though possible and should be inspected).
The latter condition requires a new clutch assembly to be installed.
Use of Mazda parts are recommended.

QUESTION: Thank you for answering my question; what happened was, when I let off the clutch, I felt a "pop" and then I was able to depress the clutch all the way without resistance. The car was not moving at the time. Any more insights?
AnswerYour description doesn't give me a great deal of insight however, there is no rocket science to the system. The most common failure is clutch hydraulics whether it be an internal leak or an external leak the repair process is the same, both the master cylinder and the slave cylinder should be replaced as a pair.
Check under the hood driver's side in the back corner you will see two semi clear fluid reservoirs the smaller is the clutch master open the cap and look to see if the fluid is low or empty or excessively dark. Low fluid = external leak. Excessively dark fluid could indicate internal leaks (pistons worn and disintegrating)
Other than that some off the wall failure such as a pedal pivot pin or push rod failure but, not likely.
