G50 Clutch Bleed Update...

[aston@ultrasw.c]

In my experience, the Motive pressure bleeder works great for simply replacing old fluid for new.

But if the clutch hydraulics are opened up, to remove the engine for example, I can seem to get all the air out with the Motive.

I have to resort to using an assistant's foot the old fashioned way.

Don't know why...

I have always had success with the power bleeder. I don’t even bother to bench bleed anything.

But if you only jack up the rear of the car, it is not difficult to get the rear of the slave cylinder higher than the front, and it will definitely not bleed with a power bleeder in that case!

I didn't know that, I will try raising the front as well next time. Thanks.

I think I cracked it.

I removed and reinstalled the engine then bled the clutch, my usual way.

The bleed line had a steady stream of fluid, no air at all.

Off on a test drive and the clutch bites just off the floor

So engage brain.

The slave cylinder is indeed horizontal: so it would be easy for air to get trapped at the far end.

Did not want to jack the front of the car way into the air, nor did I want to remove the slave cyl.

So I loosened the slave cyl nuts a new turns.

The supply line obligingly pushed the cylinder up, so that bleed screw was now at the high point.

Hook up Motive again.

Open screw. Immediately a couple of decent sized bubbles flowed out then solid fluid again.

Tighten up.

Test drive, clutch travel is great. Bites right off the top

Great idea to loosen the slave cylinder to get the angle!

I always bleed mine when I do the annual brake fluid flush, and I have the car up on all fours for that. But for those times when it's just the back of the car in the air, I'll give this a shot next time.

BTW, that transmission is WAY too clean

G50, close ratio, LSD

Appreciate all the insight in this thread. Obligatory before and after photo (not too much after, didn’t want to waste good fluid). Now to find the leak that caused the air in the system!
