you got air in your lines. like stated above. check your slave cylinder first..
worst case scenerio the throw-out bearing is bad

Remove clutch dampner. Much easier to bleed. You may have a small leak in the stock clutch line. I experienced a similar problem. I would leak a minimal amount of clutch fluid and pedal wouldn't have good pressure. Ran steel braided line from clutch master to slave and fixed my problem. Help that helps

also take a look at the clutch pedal assembly when you push the clutch in. sometimes the spot welds on them break making the pedal drop to the floor due to nothing to compress the spring.

20 year old welds with stage 3 clutches will give out on you lol

If you have a friend handy have him engage the clutch while you are under the car and check out the slave and see what it does. That should tell you if its the T/O bearing like someone suggested. GL

How would a bad throw-out bearing cause a clutch pedal to drop to the floor?

When the slave pushes the fork if the T/O bearing i broken or w/e the pivot fork would just freely move so it wouldn't really make contact with the clutch, but I suppose you should still feel the pressure in the lines so...idk just ideas

Well, thats not a broken TOB bearing, its a broken pivot. Also if you do break the pivot, you'd also pop the slave cylinder since theres nothing to stop it from completely coming out of the housing.

oh no no i meant the fork that pushes the t/o bearing, thought it was called pivot fork, whats it called? just fork?

s14ton

clutch fork

drifttiger

mine just did the same it was the clutch fork after i replaced the master and slave cylinder

I'd start by bleeding the system(free to do) before throwing money at the problem. Hope that helps.

There is a pivot ball behind the clutch fork that can snap off pretty easily, its more likely that will break then the clutch fork but its not impossible for the fork to go.

When the TOB goes out it gets noisy but you can still more or less drive just fine, if its bad enough to cause your pedal to drop to the floor you would really hear it because that means it disintegrated and shot ball bearings at the bell housing.

get under the car check the fork and see if it wobbles all loose. Can be that your pivot ball pin snap.

I remember I clutch kicked hard one time and my pedal slam to the floor never came up.
Blew my slave cylinder and pivot ball pin.

also probably that clip that goes on the fork connecting to the pivot ball pin as well.
They are very flimsy.
If it was the ball pin highly recommend to swap that out for a new one too.
