the slave could be holding pressure, try and open the bleeder valve and connect the line.
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.
Which part do you want to replace? The slave cylider or the master cylinder? The hydraulic line and master cylinder.
It SHOULD be on the clutch slave cylinder. Follow the hydraulic line from the clutch master cylinder down to the slave cylinder. Depending on the vehicle, it could be behind the dust cover of the bell housing.
My 2.3 is hydraulic Audis have a hydraulic clutch system, with a master cylinder (in car on firewall) and a slave cylinder (outside on transmission) with a metal tube between them (which looks like a brake line).
Many of these, depending on year, came as an assembly and could not be disassembled from the line or the slave cylinder.
thetool is used to disconnect the hydraulic clutch line from the slave cylinder
If you don't see it (I assume you're talking about the clutch slave cylinder) it's probably got an internal slave. An internal slave cylinder is located inside the clutch housing. Servicing of this unit will require removal of the transmission. Do not forget to replace the roll pin and retainer clip (if equipped) that holds the slave cylinder/release bearing assembly in place. On any vehicle with a hydraulic clutch, you can find the slave by following the hydraulic line from the master cylinder to it's end.
The clutch slave cylinder on a 91 Mazda 626 DX is located on the clutch bell housing. To replace the unit, first remove the hydraulic line and turn the line cap counterclockwise. Remove the two bolts holding the slave cylinder in place. Reverse directions to install new unit.
push in line pull back teflon sleeve evenly then pull back
If the line is connected directly, without a banjo, or flare fitting, then you will have to loosen the line, unbolt the slave cylinder, and twist the slave cylinder to unscrew the line.
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.
If you're POSITIVE the clutch slave cylinder isn't leaking, there's only two other places it could come from. The clutch master cylinder or the hydraulic line in between the master and the slave cylinder. Maybe I'm confused. Isn't the clutch Master cylinder the one that the owner would check, and the slave cylinder inside the transmission?
