Apply the new vehicle parking brakes by creating a software actuation of one’s parking braking system manage
S5.6.6.5 The first criteria getting S5.6.6.cuatro are as follows: The fresh new reservoir system and provide line is pressurized in order to a hundred psi, using the supply range portion of the truck attempt rig (Contour 1).
S5.6.six.six The exam succession to have S5.6.six.cuatro is just as comes after. One solitary leakages form of failure, in just about any most other brakes, out-of a part built to have compressed air or braking system liquid (similar to the parenthetical words given from inside the S5.six.3.1), try lead on brake system. 30 seconds after the initiation of such venting, the production range try repressurized with the trailer try rig (Figure step 1). Thirty moments following the initiation of these repressurizing of your likewise have line, leading likewise have range was ventilated on surroundings. This procedure is completed possibly from the relationship and you will disconnection of also provide range coupling otherwise of the usage of a device installed into the the production range portion of the truck decide to try rig near the also provide range coupling.
S5.six.seven Limitation number of prominent diaphragm leakages-style of failure/ Comparable level of leaks on air chamber containing one to diaphragm. In the example of car by which the option in S5.6(b) might have been chose, influence the utmost amount of prominent diaphragm leakages-particular failure (or comparable number of leakage about sky chamber which has one diaphragm) according to steps established during the S5.6.7.1 using S5.6.eight.dos.step 3.
Should your automobile is made to pull a motor vehicle armed with air brake system, an effective fifty cubic inches try tank was connected to the bottom have line coupling
S5.six.seven.step one.step 1 With respect to the after the processes, dictate the new endurance quantity of popular diaphragm leaks-type of failure (otherwise comparable level of leakage on air chamber with which has you to definitely diaphragm) of which brand new vehicle’s parking brakes getting unreleasable. Which have an initial reservoir program tension out of one hundred psi, this new engine turned of, no application of the car’s brake system, and, in the event the auto was created to pull a car or truck equipped with air brake system, a beneficial fifty cubic inch shot tank connected to the have line coupling, present a leakage-method of failure of your prominent diaphragm (or comparable leaks on the air chamber who has one diaphragm). Slow down the demands throughout of your own car’s reservoirs to no, turn on brand new system and permit they so you can idle, and invite this new challenges about automobile’s reservoirs to rise up to they balance otherwise before compressor close-away from part try hit. At that time, create a launch actuation of your vehicle parking braking system handle, and find out if or not the technical setting described in S5.6.3.2 remain actuated and you will support the parking brake apps with sufficient parking retardation force meet up with the minimum overall performance given either in S5.six.step one or S5.6.dos. Do this processes having increasingly decreasing otherwise expanding accounts (any type of applies) of leakages-type of diaphragm disappointments otherwise comparable leakage, to select the minimum level of popular diaphragm leakages-kind of failure (otherwise similar quantity of leaks regarding air chamber which has you to definitely diaphragm) where all the technical mode described inside the S5.six.3.2 will still be actuated and you can hold the vehicle parking braking system apps with plenty of parking retardation forces to https://datingmentor.org/germany-herpes-dating/ meet up with the minimum show given in both S5.6.1 or S5.6.dos.
S5.six.eight.1.2 On level of preferred diaphragm leaks-type of failure (otherwise comparable amount of leakage regarding the heavens chamber which has had you to diaphragm) determined within the S5.six.seven.step 1.1, and ultizing next procedure, dictate new tolerance limit reservoir rate (for the psi a minute). That have a primary tank system stress out of a hundred psi, the latest engine turned from, no application of the vehicle’s brake system and you may, if for example the vehicles was designed to pull a motor vehicle equipped with sky brakes, a great fifty cubic inch test tank attached to the likewise have range coupling, apply actuation of the parking braking system manage. Influence maximum reservoir leakage price (from inside the psi each and every minute), the restrict speed off reduced total of air tension from the automobile’s reservoirs you to definitely results up coming parking braking system application.
