The leading likewise have line coupling are ventilated for the atmosphere

Dictate maximum tank leaks rates (for the psi a minute), the restrict rates out of reduction of heavens tension away from any of the car’s reservoirs you to definitely abilities following vehicle parking brake app

S5.6.6.5 The first conditions to own S5.six.6.cuatro are as follows: New reservoir system and supply range is pressurized to a hundred psi, making use of the also provide line portion of the truck take to rig (Figure 1).

S5.6.6.6 The test series getting S5.6.6.4 is just as uses. Any solitary leakage particular inability, in any almost every other brakes, from a part made to have compressed-air otherwise brake fluid (consistent with the parenthetical terminology specified during the S5.six.step 3.1), is delivered on brakes. Thirty moments adopting the initiation of such ventilation, the supply line is actually repressurized on trailer test rig (Figure 1). Thirty mere seconds following initiation of such repressurizing of likewise have range, the front likewise have range is actually ventilated to your ambiance. This process is performed possibly by relationship and you can disconnection of your likewise have line coupling otherwise by the accessibility a valve strung for the the supply line portion of the truck take to rig close to the likewise have range coupling.

In case the auto was designed to pull a car or truck armed with air brakes, an excellent 50 cubic inches take to reservoir are attached to the bottom also provide range coupling

S5.6.7 Maximum level of prominent diaphragm leaks-sort of incapacity/ Similar number of leaks throughout the sky chamber that has one diaphragm. In the case of vehicle by which the option inside S5.6(b) could have been selected, determine the maximum quantity of common diaphragm leakage-style of failure (or similar quantity of leakage on the air chamber that has that diaphragm) with regards to the procedures set forth for the S5.6.eight.step 1 as a consequence of S5.six.7.2.step 3.

S5.six.seven.step 1.1 Depending on the pursuing the process, influence brand new endurance number of prominent diaphragm leakages-sort of inability (otherwise comparable amount of leaks on the air chamber which includes that diaphragm) from which the automobile’s parking brakes become unreleasable. With a first tank system stress away from one hundred psi, this new engine turned of, no applying of any of the car’s brakes, and, in the event your automobile was created to pull an automobile armed with heavens brakes, a beneficial fifty cubic inches test reservoir connected to the also provide line coupling, expose a leaks-type of incapacity of the well-known diaphragm (otherwise equivalent leakage on the heavens chamber that contains you to definitely diaphragm). Pertain the newest vehicle parking brakes through an application actuation of the vehicle parking brake control. Reduce the challenges in every of automobile’s reservoirs in order to zero, turn on the fresh system and invite they in order to idle, and allow the brand new pressures on automobile’s reservoirs to go up up until they balance out otherwise up until the compressor close-of point was reached. During the time, create a release actuation of parking brake handle, to check out whether all the technical mode known from inside the S5.6.3.dos will always be actuated and you can hold the vehicle parking braking system software with sufficient parking retardation force in order to meet the minimum performance specified in both S5.six.step 1 or S5.6.2. Do that processes with increasingly coming down otherwise increasing membership (any kind of applies) of leakage-kind of diaphragm downfalls or similar leakages, to search for the minimum quantity of common diaphragm leakages-variety of inability (otherwise equivalent level of leaks throughout the air chamber which has you to diaphragm) of which most of the technical setting known in the S5.six.step 3.2 continue to be actuated and you can hold the vehicle parking braking system apps with enough parking retardation forces to meet the minimum show specified in both S5.six.step 1 or S5.6.dos.

S5.6.seven.1.dos On level of preferred diaphragm leakage-sort of failure (or equivalent quantity of leaks regarding the sky chamber that features https://datingmentor.org/heterosexual-dating/ one to diaphragm) computed from inside the S5.six.7.1.step 1, and making use of the second process, determine the fresh threshold limitation tank price (during the psi a minute). That have an initial reservoir system tension out of 100 psi, this new engine-turned of, no applying of all automobile’s brakes and, in the event your automobile was created to pull a car or truck armed with air brakes, a good fifty cubic inch try reservoir connected to the likewise have line coupling, make an application actuation of your parking braking system control.
