    i would try vacuum bleeding the lines. and int is possible to have a collapsed rubber line at some point in the system.

    Did you have solid fluid coming out of the bleeder screws when you manually bled the brakes before.

    and those masters, with the cover off and you step on the brake pedal it will always spit brake fluid out the top.

    Actually it should be rr, lr, rf, lf.
    What kinda streams were coming out of the breeders? And are the rear brakes adjusted probably?

    how are the rotors? if they are worn out it makes it like your pushing down harder on the pedal. What was that other thing? Make sure the bleeders are on top.
