Clutch

    Need some advice.

    Tried to move the zed Tuesday and had no clutch, felt like a feather could push the pedal in.

    Got a new slave cylinder and fitted it today, bled the clutch in from both points as normal. Still no clutch. Noticed in neutral the rear wheels were spinning (normal) but it took a decent amount of force to stop them. (Not normal)

    Got a little bit peeved and forced the gearbox through the gears with engine off. Miraculously I now have clutch.

    The last time I drove it I scraped on a speedhump

    Wtf is going on with this.

    Did I damage the old slave somehow with the speedhump (kinda unlikely as it hides up on the side of the tranny)
    Or is there something more sinister.

    Can the seals in the master pop and fix themselves? Does this happen?

    I'm at a loss to why it suddenly works now. I was all ready to put her under the cover for a month while I save for a new clutch or box. Thought I'd give it one more go before it got too dark n sh!t.

    Any advice / insights would be helpful

    Hi,
    I got to admit, that is a strange one.... I've never heard of that before.

    I do know that the arm that the slave pushed can have a number of issues.

    1 - the ball fulcrum point can have problems (i.e. broken)
    2 - the arm could come off the fulcrum
    3 - the thrust race could come out of the arm
    4 - the slave could have some problems

    I can't really see how a problem that bad could come and go particularly since you're positive it's the clutch and the really light clutch issue..

    then again maybe a pedal or master cylinder or power assist issue (not too sure how it would be the last one but you are better off checking everything).

    sorry I couldn't be of more help. :)

    I've really got no idea either.

    Some rough work changing gears while engine off solved it

    Can the arm / Fulcom get stuck?

    My mate said perhaps a seal in the master popped, then magically sealed itself. Not sure how feasible that is though.

    Ill be keeping an eye on it though, may even go talk to my mechanic on Monday, see what he reckons.

    It could get a bit stuck, maybe when less force on it, the hard bump on the speed hump might have caused it to go into a strange position... but that is just speculation on my part..

    if there is an issue with the master you may be able to see a slight leak on the firewall either in the engine bay or behind the pedals.

    good luck.

    Two issues seem unrelated.

    The light clutch pedal is one issue. The other is that it seems that the wheels are engaged when car is raised.
    1. When you noticed the wheels spinning was the car in neutral or in gear

    2.Did the above occur while the clutch was not working or after is began to work?

    Details are important if forum members are to accurately assist other members.

    Agreed, could be unrelated. I came out one morning to find I had no clutch but normal pedal feel. Turned out for some reason the clutch disc had stuck itself to the flywheel. More common on cars that are left sitting for long periods of time, but by forcibly stopping the wheels spinning that may have been enough to break the bond between the disc and flywheel.

    the car was only sitting for a couple days, would this be enough time for the disc to stick to the flywheel?

    Even in neutral the clutch is still engaged, neutral disengages the gearbox. Mine happened overnight so id say quite plausible.

    The flywheel is normally stuck to the clutch plate when the clutch pedal is not pressed so this would not cause the problem of the wheels spinning.

    Sounds like the gearbox was not in neutral or something in the gearbox is causing the gears to engage slightly.

    I suggest you drain the gearbox oil and check for any metal fragments in the oil.

    But that doesn't explain the clutch being non existent.
