Scope
This SAE Recommended Practice provides the test procedure and instructions for air braked single unit trucks, buses, and combination vehicles. It also provides recommendations for:
-
a
Instrumentation and equipment
-
b
Vehicle preparation
-
c
Calculating distribution of brake force
Rationale
New stopping distance regulations will require a shift in brake force distribution. In addition, new types of brakes such as air disc have different pressure onset and torque output characteristics that can effect low pressure brake force distribution. This procedure therefore will become a more important tool for measuring and comparing brake force distribution on trucks and buses. Experience with the original procedure has shown that test organizations using it would benefit from changes in data recording and safety procedures.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
