Have a question for you if you are. Just went through the painstaking process of bleeding the system of air. At first, the whole system groaned at wheel turn, and especially brake press. I did hours of the engine off, turning wheel side to side, pumping brakes a few times, refilling, and repeating. I did this probably 30 times, as one video recommended.
I
think I have the air out of the system. The challenge is that I have no wheels or tires atm, so I can't really drive it to see how brakes feel. I do notice the pedal travel feels much shorter, and it almost feels like there are two "steps" towards the end of brake travel. When I hit the first step I hear a slight groaning in the system, kind of like when you hit lock with the steering wheel. Is this normal?
Here is a video I took demonstrating:
