Am looking for specs/charts concerning braking force of air brake equipped heavy vehicles.
Had charts by Heusser (sp) but cannot find where they came from (Several years old).
This chart showed braking force applied when air pressure supplied and chamber
size were known (Area x PSI=Force)but also factored in push rod stroke/length
as well as slack...I realize this is a LONG set of equations and any help would be
GREATLY appreciated. I am helping my Lt with his research...I got the toughie!
Thank You.
