Bleeding turbo brakes

[Fairview]

With the turbo brake system the calipers each have two bleed screws. I can’t find any instructions on which bleed screw should be bled first. Or does it even matter? Thanks for your guidance.

It does not matter. In my experience, sometimes the bleed screws are a little stuck, so I use a deep socket to crack them open, then closed. And the when bleeding I almost always use a box end, offset spanner.

I usually use my Mityvac, sometimes I use my Motive tool. The Motive works well and I know the owners of that company. They are car guys.

The best/quickest way to purge those calipers is to open both bleeders together.

bleeding starts always from the bleeder nozzle the furthest from the reservoir away.
so for the two-bleeder version calipers (930, 964, etc), you bleed from the outside to the inside.
for a proper bleeding of these types of calipers you'll need double the liquid as for regulars.

regular calipers (S/SC/Carrera):

right/rear
left/rear
right/front
left/front

doubles:

right/rear/outer
right/rear/inner

left/rear/outer
left/rear/inner

right/front/outer
rights/front/inner

left/front/outer
left/front/inner

That is a bunch of unnecessary work/steps for absolutely zero benefit.

REALLY?? sequence does not matter? please confirm...

[Rawknees'Turbo]

Sequence on calipers with multiple bleed screws does not matter, and in fact, it is much more efficient to open both/all of them at the same time.

And overall caliper sequence also has no measurable bearing with regard to purging air from the system (it is a long standing myth that it does). I have put this to the test many times, on many different machines, and it absolutely does not matter which caliper you begin with.
