Liquid cooled brake assembly

A brake, comprising:

• a driven shaft disposed about a rotational axis;
• first and second bearings disposed about said driven shaft;
• a housing disposed about said driven shaft;
• a first friction plate coupled to said driven shaft for rotation therewith and axially movable relative to said driven shaft;
• a second friction plate coupled to said housing and fixed against rotation relative to said housing, said second friction plate defining a fluid jacket configured for passage of a fluid;
• a first end cap assembly coupled to said housing and supporting said first bearing, said first end cap assembly including a pressure plate configured for movement in a first axial direction towards said first and second friction plates;
• a second end cap assembly coupled to said housing and supporting said second bearing;
• and,
• a spacer disposed between said housing and one end cap assembly of said first and second end cap assemblies;
• wherein adjustment of said spacer enables axial movement of said one end cap assembly relative to said housing and a corresponding one of said first and second bearings.
