If you want the best, Castrol SRF is it. Need 1 bottle for a full flush. It's advantage is wet boiling point which is about 100F higher than anything else on the market. And the wet boiling point is what reall matters for most of us who don't flush the system right before every track day

Motul RBF600 is a great fluid. You need about 2 bottles for a full flush. If you want the best, Castrol SRF is it. Need 1 bottle for a full flush.

Sounds like this is another option from what I've read. If it saves me some bleeding/flush/fill time I'll probably go with SRF.

I used the blue fluid because it was local and a different color. It made it easy to tell when the fluid was pushed out and the new fluid was in all the lines. Here is the easy way that I did it. I might not have gotten all of the fluid out of the clutch line but it's a small amount.
Use a turkey baster to suck almost all the old fluid out of the resevoir and put it into a water bottle.
Slowly fill the res with the new fluid.
Bleed the brakes until the new fluid comes out in this order....
1. Passenger rear
2. Driver rear
3. Brembo inner valve Passenger side front
4. Brembo outer valve same side
5. Brembo inner valve driver side
6. Brembo outer valve same side
As far as the clutch line, I pumped the clutch a crapload of times to get the new fluid into the line and the old fluid into the res. I sucked half of the fluid back out with the baster again and then filled it to the fill mark.
Done.

You'll notice in the fluid reservoir a partition for clutch fluid. As noted, suck out everything possible with a baster and then what I do is refill only the clutch portion of the reservoir, bleed that (pump clutch like 200 times) then suck out that fluid, refill jus the clutch portion again, repeat twice. Should get most of the fluid swapped to the new good stuff. Then I do the brakes be fully filling the reservoir

What do you guys think of vacuum bleeding? I have a mechanic friend who charges me beer to come over to his shop on a Saturday afternoon, and work on my Mustang with him. He really seems to like the idea of vacuum bleeding the Mustang.
If I recall the idea is to hook up a vacuum source to the bleeders and suck new fluid through the brakes (in the same order as listed above). Then once that's all done and there is new fluid in the reservoir hook up a vac cap to the reservoir, and suction bleed the clutch line.

It comes down to color, which I think is super dumb because it makes it easier to know it's brake fluid and not something else.
Vacuum bleeding is good if you are by yourself and don't have someone to either pump the pedal or turn the bleeder screws for you. It will for sure make the clutch portion easier as you won't have to pump the clutch pedal like 200 times.

Yup that's exactly right. Be sure to properly torque the bleeders too... I believe it's about 90-95 inch-lbs (not ft-lbs!!).

So how does the vacuum bleeder work with the clutch?
