Slave Cylinder? Clutch? ugh..

Earlier this morning I ran into a brick wall. yay me.... luckily my carbon fiber hood wasn't damaged, just looks like the bumper and a headlight.

I haven't noticed ANY issues with the clutch or transmission before this (just making sure we get that out of the way).

So I went to pull out of my driveway and I started the car and it began to pull forward.... wtf... the clutch was all the way down. so I quickly put it to neutral and slam on the brakes... too late, I hit the wall. again, luckily I was only 5ish feet from the wall.

I kill the car (yea, probably should have done that previously, I get it). and notice that the clutch is all the way to the floor, stuck. My brother and I were able to pull it out but the car isn't moving, even in reverse.

Any ideas? what to check first?

Engine off, can you shift through the gears?
Engine running (and no walls nearby), can you shift into any gear?

With a helper, when you push on the clutch pedal, does the ToB arm move? If not, maybe try disconnecting the slave cylinder from the ToB arm, can you push he clutch pedal down now?

If you can shift gears engine off, it's not stuck in 1st gear.
Sounds like you can't disengage the clutch to shift gears with the engine running.
Two separate issues.......

It definitely looks stuck in the extended position (clutch in). I would unbolt it from the tranny and see if the arm moves back. If it does, the slave is stuck. If it doesn't, there's a more serious problem.
Yep, what I would do/suggest.:wink2:

I'm guessing TOB dislodged, although I've never heard of that, nor understand how bumping into a wall would cause that. Your freeplay would have had to have been way high with extra pull available on the TOB, and your foot punched to the floor really hard on impact?
Remove the slave and make sure you can manually push the rod back in.
Try to reseat the TOB by pushing toward the rear of the car on the clutch fork arm. If it clicks back in, see if it works.
If it does, check your pedal height. Might be too high and be applying too much force.
If it doesn't snap in......

Thanks for the input. We tried moving the arm on the top of the trans and it wiggled just a little bit both as it was, and after we flipped it (so that we could see if the TOB was really ****ed which it didn't appear to be). I don't think we tried to pop anything back into place though. We pulled the slave cylinder and emptied the fluid and there wasn't much there... at all. So there is a small possibility it was low on fluid due to a leak (although we haven't found one). About to go pick up a replacement master slave cylinder and replace that to rule it out as the culprit given that we're having issues bleeding the clutch as is right now, but either way it's really starting to look like this is going to be a shops job soon.

Update:

We disconnected the fork on the top of the transmission and it's still doing the same issue. That being said it looks like the issues HAS to be the slave cylinder. We could move it manually before so we didn't suspect it to be an issue, but we've replaced the master clutch cylinder and it's doing the same thing. The slave cylinder only extends half way when the pedal gets stuck only going down half way so the only thing left is for it to be a bad slave cylinder. Ordered one today and we'll be swapping it out in about 6 hours when it comes in. Hopefully getting this to work and bleed properly we'll be able to disengage the system.

Fingers crossed!!!!

this is a complete guess, but doesn't the clutch peddle have an adjustment on it? if I remember right (it's been a while since I last saw this) doesn't it block off the reservoir unless it's completely back? If that's the case it might be a good Idea to crack the slave's bleeder and see if you can then push it back. if you could then push it back I would guess it's a not correctly adjusted master cylinder.

I'd like to help but I don't think I understand what is going on. You're saying your clutch pedal does not travel fully when you have your slave cylinder disconnected from the fork lever? When it IS connected, and your slave cylinder bleeder valve is open, the pedal should go all the way down and need to be pulled up by hand.

Assume that the system is being bench bled. When the bleeder valve on the slave is closed, we don't get full range on the master cylinder. if we open the bleeder valve, we get full range of motion.

Yeah, you have to adjust the master cylinder. if it's not fully open it'll restrict the valve inside. Did you try it all the way to the extremes of the adjustment nut?

I believe you may be right, but even without the clutch fork connected to the slave, the same issue is present. Which means there's another issue present that isn't related to the clutch at all. I would think at least. it's a pretty straight forward system. we should be able to get pressure even without the fork connected. or am I wrong?

****RESOLVED****

Clutch completely took a **** (as expected).

The metal reinforcement bar had a small piece of the metal jam into one of the bricks. So much so that the tow truck had issues pulling it off at first.

Car wasn't stuck in 1st after all. Yay.

Reinforcement bar? Bricks? What? lol

Should never have bricks in your transmission..lol
Something got stuck in your brakes?
Ok. So ...is your slave cylinder figured out? Everything good?

Ummmmmm.......yep, "what?"..........

Is this from hitting a wall, or something else? Obviously I'm not the only confused person here......:wink2:
