Dot 4
If and when changing\flushing the DOT 4 fluid and the old fluid looks clear, how can you tell when the old fluid has been flushed?
When checking my front brake fluid level, I noticed moisture behind the rubber cap, but none in the DOT 4 fluid itself.

Empty the bottle the drained flush fluid goes into, then flush a little more into the bottle so the fluid is clear then measure it. Once you are at or below 1% you are good.

To properly bleed one with ABS you need the software to cycle the abs while bleeding. I use Daytona Twin Tec. You can do a manual regular bleed, but the equipment cycles the abs while bleeding to ensure complete flush and new fluid in the ABS unit.
