I'm about to flush the front brakes, can you post a link to where you found those speed bleeders? The company's website does not list our 821s.
Used this spec from the manual:
Bleeder fastener (front right+left calliper)
M6x1
I also found that it is critical to remove the calipers and push the pistons in. This clears the abs system and assures a firm lever after all is done.
