All you have to do is let it gravity bleed.
Just open the bleeder valve on the transmission and have someone watch the fluid level in the resavore.
It might take a few minutes but that's the easiest way that I have found.
you dont. its hydraulic, and its adjusting.
Actually , the clutch is operated by a cable so there isn't a clutch reservoir like there is on a hydraulic clutch
The clutch is hydraulic, and as such self adjusting. There is no way to manually adjust it.
Changing the clutch on a 1999 Chevy Cavalier requires remove of the transmission. Once the unit is dropped. Access and loosen the flywheel bolts. Then remove the clutch dish bolts. Pull the clutch off. Installation and reversal of the removal, just be sure the properly bleed the clutch system.
under the brake booster
There is a bleeder valve on the slave cylinder of a 1999 1500 pick up. Have a helper press the clutch down slowly while you open the bleeder valve. let the air escape, then close the valve. Have the helper pump the pedal again and repeat until all of the air is gone.
gravity bleed the slave cylinder. then use a brake bleeder pump to pump fluid into the slave cylinder's bleeder valve. you will have to use a tool or turkey baster to remove the excess fluid from the reservoir and you pump the bleeder to prevent it from over flowing. do not reuse this fluid.
If the clutch won't engage, the clutch disc or pressure plate has probably broke apart. If the clutch won't disengage, the clutch hydraulic fluid reservoir is empty because of a leak in the system.
switch under dash on clutch is bad
Simply push the hydraulic line back into the quick release fitting. When it is pushed all the way in you will hear a "snap" then it is locked in.
Actually , the clutch on your 1999 Ford Mustang is operated by a cable , it's not a hydraulic operated clutch so it doesn't use any fluid * if you want to adjust the clutch - without the engine running put it into 1st gear - GENTLY , using your foot , pull the clutch pedal UP until it stops - SLOWLY push the clutch pedal DOWN ( you will hear a click if the clutch needed adjusting )
Ford has used hydraulically operated clutches in the F250 for a long time. You don't adjust them. You could bleed it, if the clutch feels soft or spongy.
