    I'd venture a guess that either one of your brake shoes, drums or snail cams
    are worn, or you have the shoes installed incorrectly (leading/trailing
    configuration, springs incorrectly installed shoe post to shoe post).
    Are ALL brake parts new, w/c's, shoes, drums ???
    You can bleed the M/C on the truck by loosening the M/C pipe fitting at the
    M/C and which goes on to the wheel cylinders, then pump pedal once(or apply
    air pressure) and re-tighten the fitting as if it were a w/c bleed screw.

    Can anyone please tell me how to bleed the CB type Master on a single
    circuit non boosted SWB Land rover is bled.
    I have pressure bled it down, I have sucked from the bottom. I have
    even pressure bled up from the wheels.
    What it is doing is the following.
    All parts are new.
    I can pump up the pressure and it will hit the floor a few times then
    hold. When holding, it will not fade, it will hold. Subsequent pumps
    willk also hold without fading and the brakes are strong. BUT if I let
    off the pedal and leave it for a few miniutes and then press it again,
    it will go to the floor again until I pump it. It is a new CB master
    type cylinder.
    Do you have to prime these? How do you do this?
    Thanks for all your help.
    Kind regards,
