A round of thorough pedal bleeding of all 4 corners in the right order produced zero air and pedal still does the same.

You guys are right, pedal bleeding does not require big strokes. But my helpers are not experts, so I am just glad they can do the procedure okay with me under the car. 1) put foot on pedal to build pressure 2) open bleeder 3) Pedal sinks towards floor and about half way down helper announces this 4) close bleeder 5) Pedal up - repeat. Key here, the way I learned it, is that the system needs to be under pressure whenever you crack the bleeder.

My money is on the MC, because an air pocket will give a springy pedal feel like an air shock. You compress the pedal but it can come back up. If it sinks, ever so slowly, that tells me the fluid is leaking past the MC piston seal.

Now what Jeff writes about the ABS unit is worrisome. On two fronts. Maybe I got air in it and that's causing my pedal effect but worse, if I replace the MC, I may get air in the ABS unit as well? I'd get a scan tool and do it all right, but very limited on time these days.

At this point it is either spending more time installing a new MC or throwing in the towel and just get some professional help this week.

What would you guys do next!?
