Brake pushrod length.... and other brake woes

Well my little guy mistook "go slow" for " hard as you can" on the brake pedal when I had the MC lid.

huge geyser came out must be air. I saw some pedal improvement with rear adjust and pumping.

Mechanically things seem good and the pushrod is firmly attached at both ends, the brake pedal stop is working, and the pedal returns to the park position

Both rear pads on both sides move when the brakes are pressed and the drums off.
