For every single car will be armed with a crisis brake system which, within the conditions out-of S6
S5
six.eight.dos.1 According to after the procedure, dictate new threshold amount of prominent diaphragm leakages-type of incapacity (otherwise equivalent number of leakage on the heavens chamber that features one diaphragm) at which the latest vehicle's vehicle parking brake system be unreleasable. That have a first tank program and provide line stress away from a hundred psi, zero application of all automobile's brake system, and you may, if the automobile is made to pull an auto armed with sky brake system, a great 50 cubic inch take to reservoir connected to the also provide line coupling, establish an excellent leaks-sorts of failure of one's well-known diaphragm (otherwise equivalent leaks in the air chamber that contains you to definitely diaphragm). Pressurize the supply range by connecting the new trailer's front side also have range coupling towards have line part of the truck shot rig (Contour step 1) to your regulator of your trailer test rig put during the 100 psi, to see whether or not every physical form labeled inside the 6.step 3.2 are still actuated and keep the parking brake apps with sufficient parking retardation pushes to generally meet the minimum results given in a choice of six.1 otherwise six.dos. Try this procedure with progressively coming down or expanding account (almost any enforce) regarding leaks-sorts of diaphragm downfalls otherwise similar leakages, to select the minimum amount of prominent diaphragm leakages-type of failure (otherwise comparable number of leaks from the heavens chamber that has you to diaphragm) where every technical setting known inside the six.3.dos are still actuated and you can keep the parking braking system software with plenty of parking retardation pushes to generally meet minimal results given in either six.step 1 or six.2.
