Liquid cooled brake with support columns

A brake, comprising:

• first and second end plates configured to be disposed about a rotational axis of a driven shaft and said first and second end plates axially spaced from one another;
• a plurality of axially extending pins connecting said first and second end plates;
• a first friction plate configured to be coupled to said driven shaft for rotation therewith and axially movable relative to said driven shaft;
• a second friction plate fixed against rotation relative to said plurality of pins, but axially movable relative to said plurality of pins, said second friction plate defining a fluid jacket configured for passage of a fluid;
• a pressure plate configured for movement in a first axial direction towards said first and second friction plates;
• and,
• a first support column disposed radially outwardly of said second friction plate and extending between said first and second end plates
• wherein said first support column defines first and second axially extending bores configured to receive fasteners fixing said first and second ends of said first support column to said first and second end plates.
