So it specifications are came across one another having and you will without the solitary leakage-type inability, in just about any other brake system, off a part made to include compressed-air or brake fluid (consistent with the parenthetical terminology given inside 6.step 3.1).
6.5.4 The original conditions for 6.5.step three are listed below: The brand new tank program and provide line try pressurized to help you 100 psi, utilizing the likewise have line portion of the truck take to rig (Profile 1).
