There MUST be free play (slack) at the foot pedal else the return hole is
blocked and the brakes will never release.......

This could well be caused by improper adjustment of the pushrod. This
will probably be discussed in the WSM.
I had the same problem years ago with another car. I just adjusted the
rod according spec and all was fine.
Another cause can be the valve in the MBC being at fault or a non
fitting MBC. In that case contact the supplier.
