At the time, build a release actuation of your own vehicle parking brake manage, and find out whether or not most of the mechanical mode known in S5
S5.six.6.5 The first conditions for S5.six.six.cuatro are as follows: The fresh tank program and gives range try pressurized so you’re able to 100 psi, with the supply line part of the trailer take to rig (Profile step one). When your car is designed to tow an auto equipped with sky brake system, an excellent fifty cubic inch attempt reservoir is linked to the rear likewise have line coupling.
Thirty mere seconds after the initiation of these ventilation, the production line is actually repressurized on trailer test rig (Contour step 1)
S5.6.6.6 The exam sequence to own S5.6.six.4 is just as employs. Any unmarried leaks variety of inability, in any most other brakes, out of a part designed to have compressed air otherwise brake fluid (similar to the parenthetical statement given from inside the S5.6.step three.1), are brought throughout the brake system. 30 seconds adopting the initiation of such repressurizing of the supply line, the front likewise have line try ventilated to your conditions. This process is gay dating app France carried out often from the relationship and disconnection of one’s also have line coupling or because of the the means to access a valve installed for the the production range portion of the truck try rig nearby the have line coupling.
S5.six.seven Limit level of preferred diaphragm leaks-type inability/ Similar quantity of leakages regarding heavens chamber with you to definitely diaphragm. In the case of vehicles wherein the option in the S5.6(b) has been elected, influence maximum level of preferred diaphragm leakage-form of failure (otherwise comparable amount of leakage regarding the sky chamber containing that diaphragm) with regards to the tips established from inside the S5.six.seven.1 due to S5.6.seven.2.step three.
S5.six.seven.step one.step one According to the following processes, determine the newest threshold amount of prominent diaphragm leaks-sorts of incapacity (otherwise equivalent amount of leaks from the air chamber which includes you to definitely diaphragm) at which the fresh new car’s vehicle parking brake system be unreleasable. Having a first tank program pressure away from 100 psi, the engine-turned regarding, zero application of all vehicle’s brake system, and you may, if your automobile is made to tow an automobile armed with sky brakes, a great 50 cubic inches decide to try reservoir linked to the likewise have range coupling, expose an excellent leakage-sorts of inability of common diaphragm (or similar leakages on the sky chamber that has you to diaphragm). Incorporate the latest vehicle parking brake system through a software actuation of your own vehicle parking braking system control. Slow down the demands in every of your vehicle’s reservoirs in order to zero, turn on the fresh engine and permit they so you can lazy, and allow the new demands about automobile’s reservoirs to increase up until they balance out or till the compressor closed-out of part try attained. 6.step 3.2 will always be actuated and you may secure the parking brake programs with sufficient parking retardation force to generally meet minimal abilities specified in both S5.six.step one or S5.6.2. Repeat this procedure that have progressively decreasing otherwise increasing accounts (any sort of can be applied) from leakage-type diaphragm failures or comparable leakage, to determine the lowest quantity of common diaphragm leaks-type inability (otherwise comparable level of leaks about heavens chamber which includes you to definitely diaphragm) from which the physical function regarded within the S5.6.3.dos remain actuated and you can contain the vehicle parking braking system applications with sufficient parking retardation pushes to meet minimal overall performance specified in both S5.six.step 1 or S5.six.dos.
S5.6.seven.step one.dos At amount of well-known diaphragm leakages-sorts of incapacity (or similar level of leaks about air chamber which includes that diaphragm) calculated within the S5.six.eight.step 1.1, and utilizing the following techniques, determine the new threshold limitation tank price (in psi for each minute). That have a primary tank program pressure out-of 100 psi, brand new engine turned off, zero application of the car’s brakes and you will, if your car is made to pull an automobile equipped with heavens brake system, a great fifty cubic inch take to tank attached to the supply range coupling, apply actuation of one’s vehicle parking braking system manage. Dictate the maximum reservoir leaks speed (in psi per minute), the limit rates away from reduced amount of heavens tension of any of the car’s reservoirs one to performance following parking braking system software.
