GENUINE SPICER SER VICE PARTS
Should a brake assembly require replacement component parts, it is recommended that Spicer
Brake Service Parts be used. Spicer Brake Service Parts are manufactured under the same rigid
specification as are original equipment brake components. This assures the customer who uses
genuine Spicer service parts, maximum reliability for a Spicer Brake assembly. They may be
obtained through your vehicle manufacturer. The use of non-original Spicer service parts may
cause premature compontent failure and may void the warranty.
The items included in this book are currently being offered as service parts at the time of
printing. The part numbers and illustrations are provided specifically for reference purposes
only. Therefore, Spicer reserves the right to update this manual without notice or liability.

The brake assembly may be identified by a tag which is
