Subject: Obtaining Assembly Part Numbers Using the Body Casting

Number

With the ever increasing number of models and brake options available on hydraulically
braked vehicles, application information is more important than ever. While casting
identification and cross reference listings are published by all leading suppliers of
hydraulic brake components, these listings all include a statement which cautions
against using the information presented as the SOLE SOURCE of information. In the
case of the Bendix INTERCHANGE GUIDE, a caution appears in a box in the center of
each page which states “USE AS A GUIDE ONLY REFER TO APPLICATION
CATALOGS”. Casting numbers and the interchange listings for them should only be
used to confirm or support the information presented in the application catalogs.

A number of customer telephone inquiries are received daily, requesting help in
converting casting numbers to assembly piece numbers. On rare occasions help can be
given, but only when a casting is used to make just one assembly part number. Help
cannot be given in the majority of cases since a single casting is machined or assembled
in different ways to make many different assemblies. It is not at all unusual to find that a
single casting is used to make as many as 20 different assemblies. This is especially
true of master, clutch, slave, and wheel cylinder castings.

When a vehicle make, model, or year is not presented in the application catalog and/or
the vehicle parts manual, the vehicle manufacturer or dealer should be consulted for the
appropriate assembly part number.
