What is the maximum allowable separation between brake lining and shoe?

The maximum allowable separation between the brake lining and the shoe is critical for ensuring optimal braking performance and safety. A separation of 1/16" is specified because it ensures that the brake lining makes proper contact with the brake shoe. This contact is necessary for effective stopping power and to prevent issues such as uneven wear or potential failure of the braking system.

In brake systems, if there is too much separation, it may lead to inefficient braking, increased stopping distances, and an overall reduction in safety. Therefore, the specified maximum of 1/16" strikes a balance between allowing for necessary clearance while ensuring that the braking components function effectively together. This standard helps to maintain the integrity of the braking system and ensures a reliable performance during operation.
