Clutch woes.

Shit mate. Bad new on your clutch issues. I can only suggest to replace all the rubber hoses aswell. Being the original hoses they are probably swelling up when everything starts to warm up and not holding pressure. That would be my next thing to do then reassess.

So over 6 months and a lot of money later and I am still having clutch problems... everything in the hydraulic system except for some of the lines (which are not leaking) is brand new. New slave and master cylinder, new second hand booster, new clutch and flywheel.
I'm finding that when I first start the car, the clutch is perfect. But after driving for a while, the friction point of the clutch moves up the pedal. I don't know if it is dependent on temperature, but that's what I'm thinking?
So at first the friction point is pretty close to the floor which is fine. But after 10 mins or so it starts getting closer to the driver. On our last Licola trip it had moved so far the clutch started slipping, I haven't driven the car since this trip though.

Could it possibly be a vacuum issue? Any other ideas?

I am pulling my hair out with these bloody clutch dramas!

pull the plug out of the bell housing see what is there
check the breather lines 2 the gear box
way of base but you never know

That makes sense. I'll try that first I think. I'll grab the braided hose kit from Roadrunner tomorrow arvo and see how it goes.

When you put the master cyl on did you check the clearance on the pushrod? If your clutch is slipping it's either the clutch fork is starting to engage or the friction material is starting to slip, maybe rear main seal?

Yeah nice! Thats all I can think it might be. unless the push rod is not adjusted right as Gary has mentioned, but to me, it would do it all the time, not just after a bit of driving, if the adjustment was out. But who knows. Good luck. Nothing worse than having a gremlin you can't get rid of...

Sounds like it's been bloody frustrating, hopefully this solves it, best of luck. . .

I don't think it's the friction material slipping, I'm fairly sure it's the clutch fork engaging. When it started slipping the friction point of the clutch was right at the very top of the pedal.
If the pushrod was out of adjustment, that wouldn't explain the friction point shifting positions on the pedal though would it? I'll check it anyway but when the car is cold it is in the right spot.

it sounds like the fluid is expanding and not returning to the reservoir... i'd check the master / push rod to the master length.

I picked up the braided hose today from roadrunner so will put that in over the weekend.
I'll double check the push rod behind the master too while I am at it.
Anything else I should check?

Does the master have a bleed off for excessive pressure?
With the bigger exhaust and higher engine bay temps could it be heating the oil in the lines which is applying pressure to the clutch?
