Incorporate new parking brake system by simply making a credit card applicatoin actuation of your vehicle parking braking system manage
S5.six.6.5 The first criteria to have S5.six.six.cuatro are listed below: This new tank system and offer range was pressurized so you’re able to one hundred psi, utilizing the supply line part of the truck attempt rig (Profile step 1).
S5.6.six.6 The test series to possess S5.6.6.cuatro is really as observe. People solitary leakage type of incapacity, in every most other brakes, off an associate made to incorporate compressed-air otherwise brake fluid (similar to the parenthetical phrase specified inside the S5.six.step three.1), is produced throughout the brake system. 30 mere seconds following the initiation of these venting, the supply line are repressurized towards the trailer try rig (Contour step one). 30 moments adopting the initiation of these repressurizing of your own have range, the front have range was vented into environment. This process is conducted both by commitment and you will disconnection of one’s likewise have line coupling or by the use of a valve installed within the the production range part of the trailer attempt rig close to the have line coupling.
S5.six.seven Maximum level of common diaphragm leaks-type inability/ Similar level of leakage from the sky chamber with one diaphragm. In the case of vehicle where the choice inside the S5.6(b) might have been picked, determine the most quantity of popular diaphragm leaks-variety of failure (otherwise similar amount of leakage in the air chamber with that diaphragm) according to measures set forth when you look at the S22.214.171.124 courtesy S5.6.eight.dos.step 3.
Should your automobile was designed to pull an auto equipped with air brake system, good fifty cubic inch attempt tank was attached to the butt also provide range coupling
S5.6.7.step 1.step 1 With regards to the after the techniques, dictate the latest tolerance number of well-known diaphragm leakage-type of incapacity (otherwise comparable level of leakage regarding air chamber that features you to definitely diaphragm) of which the fresh vehicle’s vehicle parking brake system become unreleasable. That have a first tank system stress regarding a hundred psi, the new engine turned out of, zero application of any of the car’s brake system, and you can, if the car is designed to tow an automible equipped with sky brakes, a beneficial fifty cubic inches attempt tank linked to the also have range coupling, establish a beneficial leakage-type of failure of prominent diaphragm (or comparable leakage about sky chamber that has had one to diaphragm). Reduce the demands in every of the car’s reservoirs to zero, turn on the fresh new motor and invite they in order to sluggish, and allow the latest demands from the automobile’s reservoirs to rise up to it stabilize or before compressor shut-from part was achieved. During the time, build a launch actuation of the parking brake control, and see if most of the mechanical means known when you look at the S5.6.3.dos remain actuated and you will secure the parking braking system applications with plenty of vehicle parking retardation force meet up with the minimum performance specified in either S5.six.1 or S5.six.2. Do that process that have increasingly decreasing or growing accounts (any kind of is applicable) out-of leakages-type diaphragm disappointments otherwise equivalent leakage, to choose the minimum amount of preferred diaphragm leakage-sort of inability (or similar amount of leakage regarding sky chamber that has had you to definitely diaphragm) where all of the technical mode referred to within the S5.six.3.2 will always be actuated and contain the parking braking system software with sufficient parking retardation pushes to get to know minimal abilities specified in both S5.six.1 or S5.six.dos.
S5.6.seven.1.dos At number of common diaphragm leaks-method of incapacity (otherwise comparable level of leakage regarding the air chamber with which has you to diaphragm) determined inside S5.six.7.step one.step one, and ultizing the following techniques, dictate brand new endurance limitation tank rates (during the psi each and every minute). With a first tank program pressure of a hundred psi, the fresh new engine-turned of, no application of any of the automobile’s brake system and you will, in case the vehicle is made to pull a motor vehicle equipped with heavens brake system, an excellent fifty cubic inch try reservoir connected to the have range coupling, apply actuation of vehicle parking brake handle. Dictate maximum tank leakages rate (from inside the psi a minute), the maximum rates from decrease in heavens stress of all vehicle’s reservoirs that abilities after that parking brake application.
