Use brand new parking brake system by simply making a loan application actuation of your own vehicle parking braking system control
S5.six.six.5 The initial standards for S5.6.six.4 are as follows: The newest reservoir system and offer line is actually pressurized so you can one hundred psi, by using the also have line portion of the trailer shot rig (Shape 1).
S5.6.6.6 The exam series having S5.six.six.4 is just as uses. One solitary leaks type of failure, in every almost every other brake system, off a member built to consist of compressed-air otherwise braking system fluid (similar to the parenthetical keywords specified during the S5.six.step 3.1), are lead throughout the brake system. Thirty seconds following initiation of such venting, the production range are repressurized on truck attempt rig (Contour step one). Thirty stisknД›te strГЎnku seconds adopting the initiation of these repressurizing of your own likewise have line, the leading also provide line is actually ventilated to the atmosphere. This method is carried out either by the connection and you will disconnection of likewise have range coupling or because of the the means to access a valve hung when you look at the the production line portion of the trailer try rig around the also have range coupling.
S5.six.seven Limitation number of common diaphragm leakage-particular inability/ Similar level of leakage from the heavens chamber which has had one to diaphragm. In the example of vehicle for which the option for the S5.6(b) might have been decided to go with, influence the maximum quantity of well-known diaphragm leakage-form of inability (otherwise comparable amount of leaks on the heavens chamber that has had you to diaphragm) according to the tips set forth when you look at the S5.6.7.step one by way of S5.6.seven.2.step three.
In case your vehicle is designed to pull a motor vehicle armed with sky brakes, a great 50 cubic inches take to tank is attached to the bottom also provide line coupling
S5.six.seven.step one.1 According to after the process, determine the latest threshold level of popular diaphragm leakages-form of failure (otherwise equivalent level of leakages from the heavens chamber with which has you to definitely diaphragm) from which new car’s vehicle parking brakes end up being unreleasable. That have a primary reservoir program pressure off a hundred psi, brand new engine turned off, zero applying of any of the automobile’s brake system, and, in case your vehicle was created to tow an automible armed with sky brake system, a beneficial 50 cubic inches try tank connected to the likewise have line coupling, expose an excellent leakage-variety of inability of one’s popular diaphragm (or equivalent leakages regarding air chamber which has had one to diaphragm). Slow down the challenges in every of your vehicle’s reservoirs in order to no, turn on the newest system and invite they so you’re able to lazy, and invite this new pressures from the car’s reservoirs to increase up until they balance out otherwise before the compressor sealed-of section is actually reached. At that time, make a production actuation of the parking braking system control, and watch if every mechanical means referred to for the S5.six.step three.2 are actuated and you may contain the vehicle parking brake software with enough parking retardation push meet up with minimal overall performance given in either S5.6.step one or S5.6.2. Repeat this procedure that have more and more coming down or broadening account (any type of applies) off leakages-method of diaphragm failures or equivalent leakage, to choose the minimal level of common diaphragm leakage-kind of failure (or similar level of leakages on air chamber containing you to diaphragm) at which all of the technical function regarded from inside the S5.six.step 3.dos are actuated and contain the parking braking system software with enough parking retardation forces to meet up minimal overall performance specified in either S5.6.step 1 otherwise S5.six.2.
S5.6.eight.step one.dos Within number of preferred diaphragm leakage-style of inability (otherwise similar amount of leakage about heavens chamber which has had one diaphragm) calculated inside the S5.six.seven.step one.step 1, and using next techniques, dictate the brand new endurance limit reservoir rates (in the psi per minute). Which have an initial reservoir program stress away from 100 psi, new engine turned of, no application of any of the car’s brake system and you may, when your vehicle is made to tow an automible armed with sky brakes, a good 50 cubic inches sample reservoir connected to the supply line coupling, make an application actuation of one’s parking brake control. Dictate the utmost tank leaks rates (during the psi for each minute), the restrict price out-of decrease in air stress off all automobile’s reservoirs you to efficiency then vehicle parking braking system software.
