Default Brake fluid flush question

Today I was doing my every-2-year brake fluid flush on my BMW.
I had finished with the two back wheels, and was starting on
the front passenger side wheel, when I sheared off the bleed
screw on the caliper DAMMIT! So, now, there's no part of
it above the caliper housing as it sheared evenly at about the
housing level. What really annoys is that I was leaving for
Florida in the morning in the car, but I wanted to finish the
flush first. I'm gonna try to find a shop that'll get the thing
out and put a new one in in the morning but may be unalbe
to on such short notice. (I tried for a while doing this myself,
but have finished with that attempt.)

This may seem like a stupid question, but it's not something
I've thought much about: If I use the car for a couple of weeks
with the front lines un-flushed, would the fluid in those lines
affect the nice clean fluid in the lines to the back wheels?
IOW, if I flush the front lines in a couple of weeks, will it
be as good as if I'd been able to do them all today? Thanks.

You know, I don't think it will at lest not very quickly, it mostly travels
up and down in the same spot.

We had to drill out and use an "easy out" to remove the broken bleed screw
on my E36.

I'd just drive the car and not worry about it, but when you do get the
bleeder screw fixed might as well flush the system completely.

Theoretically the only intermixing of the fluid would happen way up at
the reservoir, but it doesn't take that much more time...

just curious, does your BMW have those little rubber caps on the
bleeders? I've found those to be quite useful; at least I've never
owned a car that still had them that I had any problems bleeding.

I think you already know the answer or you would not have asked the
question. You will need to re-do the rear lines because some of the old
fluid will mix with the new fluid given enough time and braking cycles.

I would *not* attempt to bleed the brakes by opening the brake line at
the banjo bolt. It's hard enough to get all the air out when done
correctly. Why not just fix the broken fitting and do it the right way?

Success depends on the amount of common sense of the person(s) doing the bleeding.

I'm not saying that something went wrong when I used an ez-out, but is
there such a thing as an ez-out ez-out?

a small drill bit, and a smaller easy-out tool might work.
