[Healeys] Master Cylinder

[Keith Bailey]

    I am experiencing problems with my (suspect) Master Cylinder on my BN1
    With the Master Cylinder on the bench in a vise with the reservoir
connected
    to inlet with oil in it and the outlet connected to a pipe which is
blanked of
    there is hard pressure. When fitted back to car there is no pressure when
attempting
    to bleed brakes all the wheel cylinders are new.I feel sure the problem is
in the Master
    Cylinder but lost for answers
      Regards Keith
