CR 087478

Frequently Asked Questions

Q: What is the CR 087478 secondary brake shoe used for?
A: The CR 087478 is the secondary brake shoe for Crown RD Series electric reach trucks. It is a component of the hydraulic drum brake assembly used on Crown electric reach trucks and pallet handling equipment.

Q: What materials are used in the CR 087478 brake shoe?
A: The CR 087478 features non-asbestos friction lining bonded to a high-tensile stamped steel shoe. The material composition conforms to Crown manufacturer specifications for RD Series brake systems.

Q: Does the CR 087478 work with the CR 087473 primary shoe?
A: Yes, the CR 087478 secondary shoe is designed to pair with the CR 087473 primary shoe in Crown RD Series brake assemblies. Both shoes work together as a matched pair for proper brake function.

Q: What is the expected service life of the CR 087478?
A: Brake shoe service life varies with load cycles, brake system maintenance, and operating conditions. Periodic inspection is recommended for friction lining thickness and material integrity. Replace when lining thickness drops below manufacturer minimum specifications or when bonding shows separation.

Q: How do I know if the CR 087478 needs replacement?
A: Indications for replacement include reduced braking response, metal-to-metal contact noise during braking, uneven friction lining wear patterns, visible bonding separation, or if the lining thickness is at or below manufacturer minimum specification.

Q: Should I replace both primary and secondary brake shoes together?
A: For consistent braking performance and even wear, replace both the CR 087473 primary and CR 087478 secondary shoes together as a set. Mixing worn and new shoes causes uneven brake force distribution.
