Flush brake fluid, new pads, speed bleeders:
Off with the OEM nibs. I had a panic when I thought I cross threaded one of the speed bleeders into the top of the ABS unit, I bet that's a costly mistake. Turns out it was just the cruft the speed bleeders put on the threads for some reason makes them feel like they're cross threaded, <whew>

The juice:

This was a failure. Worked to suck out the old fluid from the master cylinder, but the brake fluid must react with acrylic or lexan or whatever this thing is made from because 30 minutes later it was lying in ruins on my garage floor in shards:

Cyl had some kind of snot-like … snot on the walls of the cylinder. The cyl was installed new two years ago the last time the fluid was flushed. Maybe they're serious when they say flush the fluid every year (I let this slide a year). I didn't see this stuff anywhere other than the front master cylinder.

New pads, got them from beemer boneyard. Not brave enough to try the $27 pads people are finding on ebay although who knows maybe they all come from the same factory. Maybe next time I'll try the cheaper pads. I liked these because they specifically said "make sure you have the Brembo brakes" which made me think they would fit my K.
