You bleed the clutch at the slave cylinder located near the transmission close to the radiator up front.
I would suspect a weak clutch slave cylinder or clutch master cylinder which may be preventing the clutch from disengaging fully; The slave cylinder is connected hydraulically to the clutch master cylinder. The clutch master is where you add fluid.
There are two normal causes. The clutch is worn out or there is a leak in the hydraulic clutch slave or master cylinder. To check the clutch, press the clutch slave cylinder down. If the clutch slave cylinder bellows compresses down to the slave cylinder, the clutch is worn out. Check the clutch master cylinder fluid level. if this is low, then the clutch cylinder need to be checked. To check for a hydraulic leak in the clutch slave cylinder, remove the cylinder's bellows and check for any fluid. If fluid is present, rebuild or replace the cylinder and bleed the system. To check the clutch master cylinder, check the back the of clutch master cylinder for leaks. If fluid is present, replace or rebuild clutch master cylinder and bleed the system. In my experience, hydraulic leaks occur at the clutch slave cylinder.
At least the slave cylinder. The clutch master cylinder can be replaced at any time.
The clutch pedal assembly has a clutch rod that pushes in on a clutch master cylinder. There is a hydro line that goes from the master cylinder to the slave cylinder.
The master clutch cylinder is attached to the clutch pedal. When one depresses the pedal hydraulic fluid is forced from the master cylinder through the hard line to the slave cylinder. The piston in the slave cylinder is driven against the clutch linkage thereby releasing the clutch.
The clutch master cylinder is in the engine compartment and the slave cylinder for the hydraulic clutch is inside the manual transmission bellhousing
Whenever you are having a problem with the clutch disengaging the engine from the transmission it is advisable to bleed the clutch slave cylinder. If the clutch can't be operated by bleeding the slave cylinder then the clutch master cylinder is gone and should be replaced.
Virtually all automobiles have a brake cylinder at each wheel (a "slave cylinder"). ========================================================== A 1997 Ford Mustang has a cable operated clutch so there is no clutch slave cylinder . To adjust the clutch - Without the engine running , put your transmission in 1st gear - put your foot under the clutch pedal and GENTLY pull the clutch pedal up until it stops - SLOWLY push the clutch pedal all the way down . If the clutch needed adjusting you will hear a click
Probably the Clutch Master Cylinder or the slave cylinder.
The clutch slave cylinder , for a hydraulic clutch , is inside the manual transmission bellhousing
