External slave cylinder

[RichP]

Replacing an external slave on a YJ, same as an XJ, got the slave/master/hose yesterday in a box already assembled. Slave has a retainer on it keeping the piston retracted. No evident bleed zerk on it. Connector on the master is finger tight.
Hows this done ? Fill it with brakefluid before we install it or am I missing something ?

No instructions?
I would be tempted to fill/beed it on the bench before installing it on the truck, install it, then bleed the line by cracking it while someone else presses the clutch peddle.

I assume you bled the master before installing it?

Other than opening the box and taking it out to look at it we've done nothing yet.
I figured there would be a zerk on the slave like a brake caliper but nope, not that we can see. Going to call quadratec and ask about directions plus whatever comes across here...think I'll pull the fsm out and see whats in there. The YJ was upgraded from an internal to an external...

My YJ has been converted by swapping a XJ tranny in, so I know what your up against, I've just never had to mess with the slave yet.

I just read the FSM (last ditch effort ) and it says the assemblys are sealed units. They don't even mention bleeding

Rich, did you ever solve this?

My 94 FSM says that the external slave & master cylinder setups are sealed, and not bled. They should come prefilled with DOT3.

I'll be darned, glad I read this or it could have got messy...it's prefilled... thanks jeff...I just carefully removed the cap and looked

Pretty wild. Is that typical of American vehicles. I've never owned a manual American...only German and they all had a bleeder on the slave.

Pretty cool! I didn't expect that at all. Now that I take this info, and relate it to the FMS, the sealed unit reference makes sense

 

[ChiXJeff]

Well, Rich, what's the verdict?

Because of the short line any air will bleed on it's own back up to the Master cyclinder.

Still in the box, keith came home with a 104.8 fever on wed so it's not been installed yet. No, I'm NOT going out and freezing my ass off, he'll be using the mom mobile while she's down in florida once he gets mobile again from whatever he got...

I recently did the internal to external conversion on mine and the slave master combo is non-servicable/non-bleedable.It is filled and pre bled at the factory.So its plug and play.
