no it is hydraulic.dont know what your problem is but check clutch master cylinder and slave cylinder operation,if ok may just be a bad clutch
On the passanger side bellhousing.
Inside bell housing. Transmission has to be removed to gain access to the slave cylinder/throw-out bearing.
You will have to remove the transmission since the slave cylinder on the 91 yj is inside the bellhousing.
The clutch slave cylinder is probably at fault. Replacement is necessary to fix problem. Transmission must be removed to gain access to the slave cylinder.
the clutch and the brakes share the same master cylinder on my 1991 protege dx 1.8 sohc
On the firewall , driver side.
BAD clutch slave cylinder, wore out clutch and pressure plate.
I'm pretty sure that on that vehicle the slave cylinder is located inside the transmssion which means the transmission must be removed to replace it
bleed it the same way u bleed the brakes
Check your clutch master cylinder and slave cylinder for leaks,if no leaks,then you need a new clutch kit.
