I just ran the tests. With both wheels off the ground and the engine not running I could not turn either wheel with the brake applied. I then started the motor and gassed it and applied the brake. I could get one or both wheels to spin then the peddle would drop down but not to the floor till the abs would start to pulse. I did this several times but didn't try full throttle as I had done this test before reading the last post. I never did completely stop the wheels though. I am planning on bleeding the back brakes again this weekend. I inspected the brake lines and they look ok and don't flex when brakes applied. Any ideas??????
