    clutch master or slave, how do i pin point

    i recently lost a bit of clutch pedal, checked the master and it was down 1/3 of fluid.......i didn't have any fluid at the time but continued on as it didn't really affect the operation of the cluch apart from the pedal not always returning all the way

    i lost all my clutch pedal today....

    level in the master has not changed

    no visable leaks down the inside of the fire wall

    can i safely assume its the slave?

    my girlfriend is picking up both parts this arvo, i thought i would start with replacing the slave

    thoughts?

    If its not loseing fluid I would say the return spring in the master or the centre valve in the master are rooted.

    The clutch slave cylinder is the likely culprit but it can be an absolute bastard to work on.

    Have a good look underneath around the slave cylinder for leaking fluid. You really don't want to remove the slave cylinder if you don't really have to.

    The rod that goes from the slave cylinder piston is 'held' in the clutch fork with this stupid little @!#%%^&**' ing plastic clip thing that is an absolute bastard to re-install in situ, can be done, there was a post on here a few months ago where someone made a 'special tool' to do it.

    If you can grab the actuating rod with a pair of needle nose pliers, holding it tensioned towards the clutch fork whilst carefully removing the slave cylinder, the above mentined @!#%%^&**' ing plastic clip thing may not be dislodged . Thus saving a heap of tears, frustration and bad language.

    Also be careful when undoing the two bolts holding the slave cylinder in, the lower one of mine was rounded off and took a bit of trouble to remove. If it was the top one it would have been a mallet and oxy job.

    Good luck.

    Have a look for leaking fluid at master cyl and slave cyl, try putting some fluid in, undo the bleed screw on the slave cyl and see if you can pump some fluid through.

    A common fault (so I'm told) is that the actuating rod (or pivot) punches through the clutch fork which would give you similiar symptoms I would have thought.

    Centre valve is in the master. And as some one else posted about the clutch fork it may not be a hydraulic problem at all

    Weeds, if you happen to need a fork or any clutch bits in a hurry I have the whole lot (HD fork and Valeo clutch) sitting waiting to go in and I'm probably not going to get to the job this side of Christmas so you're welcome to use them.

    James.

    replace the slave and the master together, because they have worn together otherwise the new part will put pressure on the worn part and you will have to keep playing...
