Rear brakes are not bleeding.

I lengthened the rod from the pedal to the MC and rebled it.

Now for some more intrigue. When we go back around to rebleed the brakes. 1 pump hold, loosen bleeder screw and retighten bleeder screw. After about 3 times on the first wheel my son says the pedal “Bricks,” what he means by that is the pedal gets rock hard! Even when I go to press it, I have to use all my leg strength to get the pedal to go in at all. If I let out a bleeder screw 1 time it gets better, but if I do it more than once it “bricks” again. But when the pedal is “bricked” the rear rotors can move when not pressing the pedal and the front rotors are rock solid. When I press the pedal all rotors are solid.

Is my rod out to far now?
