: Clutch slave / remote bleeder / hose leak troubleshooting

I was making the not-quite 500mi drive from CT to VA on Tuesday, and ~60mi from home the clutch died. Pedal went to the floor and wouldn't come back up. Reservoir was almost dry, tried adding fluid, but it was coming out the bottom of the bellhousing. Awesome.

So, is it more likely to be the slave, or the line from the slave to the master, or the remote bleeder line? Is there any way of knowing the answer without pulling the trans back to get a look at everything?

I need to go back and look at my maintenance records and see what slave is in there - I can't remember if I had it replaced when I had Lindsay install a clutch and flywheel a few years ago.

Sounds like the slave. I bet the piston seal lip rolled over on you.

Edit: if you want, I have a used CS2529 LS7 slave that you can have, real cheap. I just pulled it out of the car last night. Has about 17,000 miles on it. Seems to be in good condition. I compared the amount of play and sound in the throw-out bearing to the new slave, and they appeared to equal.

Looking back at the maintenance records from when I had Lindsay install my Fidanza flywheel / clutch setup, it looks like I stuck with the stock slave and a spacer. Not quite 78k miles on this one. So, is an LS7 slave "better", or does it just allow you to ditch the spacer?

I appreciate the offer on the slave, but I think I'll go with a new one to (hopefully) maximize the amount of time before I have to do this again.

Ls7 slave allows u to ditch the spacer. But i still put in a 5mm spacer so the sweet spot was a bit higher...

Does this make the "sweet spot" more like stock?

This goes back 3 years for me, but IIRC, the compressed length of the OEM slave and the LS7 slave are identical. The LS7 slave has a longer throw and a slightly larger diameter throw out bearing, which more evenly distributes force between pressure plate fingers, improving clutch disengagement and reducing vibration when you're on the pedal.

Here's what the slave looks like. Seems like more than just a piston seal lip - I don't know what the hell happened to it, or why!

A couple thin bits of metal, presumably from the slave (but I don't know where) - 1 piece was found by the mechanic, the second bit I pulled out of the pressure plate (after using the pry bar to push the fingers down so I could get the piece out).

I don't know if I should just put this thing back together with a new slave, or what to think. :confused: I have to wonder if I frakked something up when I installed the clutch (which I did when I replaced the engine last year). I remember the clutch setup (an ACT twin disk) didn't come with much of anything in the way of instructions. Today I found these instructions (http://advancedclutch.com/media/downloadable/Instructions/EX-INS-EU-0015.pdf) on ACT's website. I'm a big fan of always doing things per procedure (the nuke submariner training), so I can't imagine that I wouldn't have gone looking on ACT's website 18 months ago to find these same instructions. As I read through them, though, they don't really ring a bell, so maybe I didn't? :( I just can't remember.

Looks as if the bearing seized to the shaft. I think I see grooves in that small piece possibly made from the pp fingers?

I would ditch the use of a spacer if I could help it.

Also, make sure your pedal return spring isn't missing or busted and don't drag your foot on the clutch pedal.

Don't ya just enjoy the crap out of pulling the bell housing?

LS7 slave on order from Luke, so the spacer will go away.
