Well I'm going to ignore that assumption.
Well got the truck on blocks, had my bro pump the brakes "Slowly" and bled all 4 calipers AGAIN 5 times per wheel, stopping between every wheel to top off master cylinder. The first time I bled the RR, I had a shot of air come out, and after that nothing but solid liquid in all 4 corners.
No change whatsoever in the pedal. Went through another quart of fluid. I dont see how air could've gotten into the ABS....The calipers were off the truck for maybe a total of 10 minutes before I had the new hoses and calipers bolted back on. Dont see how air could get that far into the system.
