Spring applied hydraulic released brake

A spring applied hydraulic released caliper brake comprising

• a caliper brake housing including
• a pair of stator assemblies,
• a pair of piston-spring assemblies, each of the piston-spring assemblies including
• a piston assembly,
• a spring assembly adapted to apply spring force to the piston assembly to thereby engage the piston assembly with a first stator assembly of the pair of stator assemblies in a default position of the brake, and
• an end cap adjuster providing an opposing surface against which the spring assembly is biased, the end cap adjuster including
• a body portion having an end cap threading therearound generally corresponding with a housing threading within the caliper brake housing,
• the caliper brake housing further including a view port with a site plug adapted to prevent fluid escape from the view port during normal operation of the brake, wherein the site plug is removable from the view port during an inspection operation of the brake, wherein the site plug is maintained by the caliper brake housing during normal operation in a position between the pair of piston-spring assemblies such that a user can view a portion of the pair of piston-spring assemblies during the inspection operation of the brake, and wherein the site plug is radially positioned relative to the pair of piston-spring assemblies.
