Slave cylinder help

So just had the slave cylinder go out.. im assuming being the clutch pedal went to the floor while driving and i had brake fluid everywhere... these trucks are heavy to push.. But anyways Its a 93 f150 5.0 5spd.. I have never replaced one of these before so anyone have a great write up or tutorial on what to do?

Hi,
Google and U-Tube is your friend!!!

I just replaced my Clutch master cylinder!

There's nothing that says it HAS to be the slave unless it's leaking from there!

My master bled on my clutch safety switch, had to change that also!!!

From my experience if you're gonna change the slave cylinder you might as well change the clutch master cylinder too. Especially if they both have the same amount of age on them.

FIRST, narrow down whether it's the slave, the master or the line. All my trucks are external slave, so I apply the above advice and replace with a complete pre-bled master-line-slave kit. But presuming yours is an internal slave, that's a lot more work; I'd be tempted to swap just the master if that's what's determined to be leaking.

This appears to be a internal slave.. so should i go ahead and change the master while im down tearing everything apart? the clutch was replaced 36k ago but i got the truck 5k ago.. SO looking over reciepts looks like neither the master or slave was replaced when the clutch was.

I would replace both, just because you don't know when or if they ever have been replaced. They aren't that expensive and just a bit of added insurance.

Just be careful that it doesn't fall off the jacks, especially if you're under it. A trans / t.case assembly is big and awkward and not the easiest to balance.

One thing I've done on my '71 Bronco a few times is leave the trans bolted to the crossmember but unbolted the crossmember from the frame. Then I C-clamped some 2x4s to the frame rails for the crossmember to sit on . That way I could move the whole thing back with no risk of it tipping or dropping. I don't know if anything like that will work with your truck, but it's an idea to have in mind.
