It's the busy time of the year at the shipping wharf so tatra work progress is near zero
But I couldnt resist taking her for a spin.
Still having major clutch problems. Starts out fine, but after 10 minutes or so it doesn't disengage properly anymore, and slowly starts to feel like the pneumatic support is failing (after 20 minutes or so I need 2 feet to even get the pedal down). After it's been stood for a day or so, all starts out fine again.
Clutch fluid is a plenty, and have bled air multiple times too. I'm thinking I might have a leak in the hydraulic line, but that's kind of weird because the problem goes away when I let the vehicle cool down).
Also thought maybe the 20w50 oil I put in there is not suited for the job, maybe becomes too liquid when under temperature.
So I figured I'll go and get a new clutch hose just to be sure, then drain and replace with hydraulic fluid.
Suggestions are welcome though. I'm not sure the system can take hydraulic fluid, for starters. Also I read in the trouble shooting section of the manual heavy clutch operation might be down to the clutch air support line being old and soft.
