    Default T56 Fork suddenly hitting and clutch slipping

    well, this is a problem I'm having a hard time finding info on. brand new clutch and flywheel, clutch was engaging/disengaging at very top of pedal travel. no issues going into gear. was downshifting blipped throttle, suddenly hear grinding noise, to the point engine stalls. release clutch pedal in gear and car restarts, notice I can't push clutch pedal down more than 1/3 before it grinds I'm assuming the fork on pressure plate.
    -i can still shift gears fine, just can't depress clutch more than 1/3 of pedal travel
    -clutch suddenly is slipping, it was holding great until this event occurred.

    The car has stock hydraulics. is it possible, remotely, that the slave is overtraveling causing grinding, and not releasing all the way causing slip? or should I suspect busted pressure plate?

    Try pulling the slave and make sure the pivot ball didn't break. Check clips on fork also. I'm betting something has the fork bound up. Not sure about slave traveling too far. I would think there's something that would prevent that from happening but I've never tried to tear one apart.

    I don't understand how I could drive it for 40 miles and suddenly it fucks up

    Don't rule anything out. Our cars are 20 plus years old now.

    yeah true. I would just think that if the pivot broke it wouldn't go INTO gear easily. I can drive it, albeit baby it before it starts slipping, and have no difficulty shifting whatsoever. just can't push clutch more than 1/3 of way down or touch throttle more than 20%.

    could a broken throw out bearing be causing the fork to go too far and also be binding up pressure plate fingers, thus causing slip?

    That's possible. Seems like the bearings that come with most clutch kits for our cars are cheaply made. Corvette bearing is supposed to be the heavier option. I've had two bearings crack where the fork pulls on the bearing.

    After some research I guess anything is possible.
