Ben,
Hah! what an idiotic thing to do!!! Hah! Yes, I did it too!!! And
for the life of me I don't know enough about PS fluid to know why it locks
your brakes up. I think it's the viscosity of it, which is greater than the
glycerine brake fluid.
My father's poor Euro 635 went through that with my idiot self. I
ended up pulling off the reservoir from the master cylinder to remove as much
of the offending stuff as I could. Then I simply bled the dickens out of the
system. And this sucker has three bleeders per front caliper, what a bear...
Flush, flush, flush. Brake fluid is cheap, esp. that DOT 3 stuff at
$2/32 oz. on sale. Admittedly this ain't the best for your BMW but it'll
work nicely to flush. Then go through a bottle of Castrol GT LMA brake fluid
or two to fill up with that: you'll see the output go from yellow to purplish
when it's getting to DOT4 stuff.
Flush, flush, flush.
