No doubt. Fortunately I *think* I have it fixed. I'm pretty sure there was just some junk in the ABS valves that had the path to the right front blocked.

After getting it cleared, I did a drive and it plugged again.

Then I just went nuts and flushed like a gallon of fluid through it, running the DSC routine on that wheel a bunch of times, and also flushed the others a couple times each. It actually plugged again in the middle of this, and then after another really difficult cycle through the procedure (brake pedal hard as a rock with the right front bleeder open) it passed a pretty big flake of debris. After that I didn't see any more particles in the fluid that passed and it kept flowing freely.

And then I did a normal bleed.

Haven't driven it a ton yet, but after a couple of short drives, all seems good.

Not that I didn't believe before, but a great demo of why you keep your brake fluid fresh!
