Parallel post brakes systems typically have large brake ratings and great thermal characteristics (no fade) 

• keep the weight applied 
  
• possible to add capacity with more weight
  
• replace the cylinder with a modern higher pressure / low volume systems
  
• paired with a brake control upgrade
  
• brake application and reaction times remain the same
  
• lowest cost option
  
• least amount of physical changes

Other considerations:

• pins and bushings
• brake block condition
• brake linkage and shoe condition

• replace weights with springs
  
• complete range of braking effort – zero to max
  
• modern higher pressure / low volume systems 
  

Improved safety, reliability and maintenance through:

• improved brake reaction time
  
• improved control
• modern cylinders with position feedback

Implementation considerations:

• minimal modifications required
  
• minimal downtime for implementation

Modern hoists almost exclusively use disc brakes

• fast reacting and easy to control
  
• easy to maintain
  

Can consider newer units if more brake torque needed

• more brake effort in same physical space
  
• improved maintenance – springs and seals
  

Check spring condition – pressure checks

• check pad conditions – Static Brake Test
  
• periodically rebuild
  

Considerations:

• highest cost option
  
• major modifications to drum for mounting discs
  
• foundation changes for brake stands
  
• longer potential shutdown for implementation
