4.5 Clutch issues!

Post by DawidT »

Hi All,

We need some advice please. The clutch on my Brother in Laws, 1999, 4.5 Patrol keeps "falling" away. He checked and even replaced the hydraulic line and could not detect any leaks. If he bleeds the clutch it would be perfectly normal and would stay OK for quite some time - up to two weeks (He is a mechanic by trade). It seems like at random it would just go flat and have no clutch at all, it would not do this during driving but only after it stood for a while. Normal pumping would not help except if he screws out the pedal stopper to allow for longer travel on the pedal. He bled the clutch with a vacuum pump and it was OK afterwards - to ensure no air in the system, but it only worked for a short while. He is not losing any break / clutch fluid. :helpsign: :helpsign: :helpsign:

David, as hy nie brake fluid verloor of lek nie sal ek se dis die master cylinder wat verby lek.
Nie seker of daar n "seal kit" beskikbaar is nie, maar glo nie dis te duur om die hele master cylinder te vervang met n tweedehandse een by David

Ek het die selfde probleem op my vorrige 4.5 gehad. As ek die pedaal terug getrêk het met die hand dan is hy weer oraait. Todat hy weer hard werk. Was die master cylinder wat se diafragma gegroet het en so die die olie laat return het nie. PM my as jy net as verwysing wil weet wat was die prys vir myne. Ek het nie rond gesoek nie so geen idee of ek teveel dalk betaal het nie.
