Brake Gap Inspection
The brake is non-adjustable with a nominal .004 inch (0.102 mm) air gap.
- The brake disc must be replaced when the air gap reaches .012 inch (0.305 mm).
- The brake spacer should be no more than .012 inch (0.305 mm) thicker than the combined thickness of the brake disc and armature plate
To inspect the brake gap, please disconnect the hoist from power and remove brake end cover (620-132). Then, please read and follow the instructions on Prostar Hoist User Manual p.9.
