Clutch assembly lost tension on clutch pedal are there any springs or fluids that need to be replaced?

so fix it

indicates no fluid in the system or air in the system
in a hydraulic it requires fluid to make the clutch disengage and also fluid to make the pedal return from the pressure of the pressure plate
if it is a cable clutch, replace the cable as the inner cable is breaking and jamming in the case

The clutch don't have spring to return. hydraulic pressure return the pedal. if you pedal go down to the flour and don't return you lost the pressure. First look in the reservoir for fluid. add DOT3 brake fluid and bleed the system. inspect for leak
Good luck

Check the spring to see if it has snapped anywhere within it's coil.

Remove the cable and check operation of the pedal and spring mechanism.
If all is well, then with a lever, check that the clutch release arm on the gearbox is operational. If that is also sticking, then you will have to remove the gearbox to investigate further.
If not sticking, then also remove the clutch cable outer sleeve, and replace.

the problem may have been in the damper spring setup in the clutch plate
it the clutch plate was a standard plate , it would have had 4 damper coil springs but the last plate fitted may have been a heavy duty plate that would have had 5 or 6 damper springs
if the springs are of insufficient tension then there is a grabbing action during clutch engagement but with more springs and different tensions that is overcome and the action is a smooth clutch application
manufacturers that have design faults quickly change the design as clutch shops are fussy when it comes to rework so I would think that it is not the clutch but an incorrect plate for the application

POSSIBLE AIR IN HYDRAUIC LINE BLEED THE VALVE KEEPING AN EYE ON FLUID IT HAS A VERY SMALL RESEVOIR. OR CHECK PEDAL RETURN SPRING MIGHT HAVE LOST TENSION.

Broken linkage, or the clutch itself has failed.

There is a return spring that lifts the clutch pedal back to the original position. It seems that the clutch return spring has got disconnected. The pedal will do its job of disengaging the engine from the gear box, but will not offer any resistance to the foot and thus give an impression of doing nothing. So, that spring should be set right. For this the clutch housing will have to be opened and the spring reset.

Replace the clutch master and slave cylinders.

Below is process for removing and replacing the clutch assembly.
Hope this helps, good luck.

REMOVAL & INSTALLATION


See Figures 1, 2 and 3



Fig. Fig. 1: Exploded view of the clutch disc and cover assembly

1. Disconnect the negative battery cable.
2. If equipped with a cable clutch (1982-84 vehicles), disconnect the cable at the clutch release lever and transaxle, as outlined earlier in this section.
3. For 1985-94 vehicles remove the sound insulator from inside the vehicle. Disconnect the clutch master cylinder pushrod from the clutch pedal.

Fig. Fig. 2: Disconnect the clutch actuator (slave) cylinder line - 1995-96 vehicles

1. Remove the transaxle, as outlined earlier in this section.
2. Mark the pressure plate assembly and the flywheel so that they can be assembled in the same position. They were balanced as an assembly at the factory.
3. Loosen the attaching bolts one turn at a time until spring tension is relieved.
4. Support the pressure plate and remove the bolts. Remove the pressure plate and clutch disc. Do not disassemble the pressure plate assembly; replace it if defective.
5. Inspect the flywheel, clutch disc, pressure plate, throwout bearing and the clutch fork and pivot shaft assembly for wear. Replace the parts as required. If the flywheel shows any signs of overheating, or if it is badly grooved or scored, it should be refaced or replaced.

Fig. Fig. 3: You must follow the specified sequence when tightening the pressure plate retaining bolts
To install:

1. Clean the pressure plate and flywheel mating surfaces thoroughly.
2. Position the clutch disc and pressure plate into the installed position, and support with a dummy shaft or clutch aligning tool, tool J 29074 or equivalent. The clutch plate is assembled with the damper springs offset toward the transaxle. One side of the factory supplied clutch disc is stamped "Flywheel Side".
3. Install the pressure plate-to-flywheel bolts. Tighten them in the sequence shown in the accompanying figure, as follows:
   1. Tighten bolts 1,2,3, then 4,5,6 in the sequence shown to 12 ft. lbs. (16 Nm).
   2. Tighten bolts 1,2,3, then 4,5,6 in the sequence shown to 15-22 ft. lbs. (22-30 Nm) plus an additional 30° turn.
   3. Remove the clutch alignment tool.
   
   
4. Lubricate the outside groove and the inside recess of the release bearing with high temperature grease. Wipe off any excess. Install the release bearing.
5. Install the transaxle, as outlined earlier in this section.

WARNING When adjusting the cruise control switch, do NOT exert an upward force on the clutch pedal pad of more than 20 lbs. (89 N) or damage to the master cylinder pushrod retaining ring may result.

1. For 1985-94 vehicles, attach the clutch master cylinder pushrod to the clutch pedal and secure with the retaining clip. If equipped with cruise control, check the switch adjustment at the clutch pedal bracket. Install the sound insulator.
2. If equipped with a cable clutch, attach the clutch cable at the transaxle and clutch release lever. Check the clutch operation by lifting the clutch pedal up to allow the mechanism to adjust the cable length. Depress the pedal slowly a few times to set the pawl into mesh with the quandrant teeth.

ADJUSTMENTS


All 1982-84 models have a self-adjusting clutch mechanism located on the clutch pedal, eliminating the need for periodic free play adjustments. The self-adjusting mechanism should be inspected periodically as follows:

1. Depress the clutch pedal and look for the pawl on the self-adjusting mechanism to firmly engage the teeth on the ratchet.
2. Release the clutch. The pawl should be lifted off of the teeth by the metal stop on the bracket.

On 1985 and later models, the hydraulic clutch system provides automatic clutch adjustment. No adjustment of clutch linkage or pedal position is required.
