Replaced clutch slave cylinder on the weekend after the cylinder seal let go. Replaced with new PBR item. Clutch worked great before I replaced the cylinder.
Now... when cold the friction point is close to the floor and once everything heats up the pedal becomes stiffer and the friction point moves to the top of the pedal stroke. ‘88 GQ with no clutch booster.
Any Ideas??
Chook

Clutch Problem After Slave Cylinder Change
I started to read your post and was about to say it is your clutch booster as that is exactly what my 92 GQ was doing and it even started to slip the more it warmed up.
Not sure if yours still has a pushrod going into the master cylinder but if so this may need adjusting as if it is out to far it doesn't allow pressure to be released or something and keeps building up fluid with each push.

GRANT84 a little bit of knowledge ah, your problem was the complete opposite, anyway
There definatly is a pushrod, the pedal just pushed on the master cylinder instead of having the booster inbetween, there still needs to be clearance between the pushrod and the master cylinder. A clutch will still work correctly even if the booster is stuffed there is just no boost.
Sounds more likely that there is air in the system though, make sure that you put the bleeder in the top port of the new slave cylinder otherwise the air gets trapped and by bleeding you only get fluid out not the air.
