Hi,
I have a '98 GU 2.8TD, stock sized tires, 2" lift, 130,000 km, have also replaced the clutch/flywheel with a safari solid flywheel and HD clutch kit (much nicer than stock).
Over the last few weeks I have noticed the clutch pedal 'sticking' on the return after being depressed.
I have examined the system, found no leaks.
I have bled the system, which improved the pedal feel, but didn't fix the return 'stickyness'.
I have found that the clutch actuated smoothly when the engine is off (no vacuum to clutch booster) and when the engine is on and vacuum booster disconnected. Thus eliminating possibility of faults in the hydraulic system or the clutch itself(throwout bearing).
Thus 'sticky' pedal behavior is only present under vacuum booster assist.
This leads me to conclude the issue is with either the clutch booster or the vacuum pump.
Ideas?
Many thanks in advance.
I have two problems listed for my patrol, the other is here http://www.patrol4x4.com/forum/niss...ntermittent-juddery-power-acceleration-60066/
