Hi Steve,

Thanks for the response.  However, I didn't see anything in there about "clutch" bleeding, as opposed to "brake" bleeding, which is what I'm trying to find out about. :)

I think the brake reservoir caps could be the same between the 4k and 5k, but I'm still trying to find out about the clutch.

One question you might be able to answer, is whether you have been able to, or it looks like you would be able to, use the Motive pressure bleeder to bleed the "clutch" hydraulics.  At least if that's true, then there's a chance the clutch reservoir caps are the same or similar.

Aw shucks, nevermind.  With your '84 you probably have a cable clutch(?), so the whole topic of bleeding the hydraulic clutch might be foreign to you.

My 5kcstq clutch is hydraulic, like the brake system, with a master and slave cylinder.  I had to open the hose to the slave to drop the tranny, and now I have to bleed it.

Tony Lum mentioned that bleeding the brake reservoir might also bleed the clutch system, as it may "feed" that circuit from the same fluid source.

I probably won't be able to get the information I need, order the Motive bleeder, and have it by this weekend anyway.  I'll have to construct my own like the one.

I suppose if the Motive import/universal kit/cap will also work on the Audi (brake in this case) master, then it might be a more flexible setup than the european-specific setup.  It appears to simply clamp onto the top of the reservoir.
