Clutch hard / vacuum issues TB45

[mowgli]

Good morning all from Kenya!
I hope you are well? Quick question for an ongoing issue I have been having with my Nissan patrol TB45 Petrol. My chassis is JN1TB5Y6120-536005. The clutch is especially hard to press in low gears and in traffic - in high gears and when driving normally is much softer. It’s been causing my serious pain in my leg and I can’t seem to find the solution. I have replaced the clutch system (pressure, release and clutch) as well as the clutch booster, master and slave. Vacuum tank / pipes are in good condition and have been pressure tested with no leaks. Has anyone had this issue before and what is the solution? Someone mentioned that the vacuum pump (not sold separately but sold together with a front cover) may be failing but that is around 700 dollars here from Nissan Kenya. I am feeling really frustrated and would be glad for any input / assistance from the experts out there.
Many many thanks 🙏🏾!

Hi mate you might like to ask your question in the engine and drivetrain section. Might be some more knowledge there
