Influence the utmost tank leakage rates (inside the psi a minute), the restriction rates from reduced amount of air tension regarding some of the automobile’s reservoirs that performance next parking braking system software
S5.6.6.5 The first standards getting S5.6.6.cuatro are as follows: The newest reservoir program and supply line try pressurized so you’re able to 100 psi, making use of the likewise have line portion of the truck try rig (Profile step one).
S5.6.6.six The test succession having S5.six.6.4 is as pursue. Any solitary leakages sort of inability, in any most other brakes, off a member built to incorporate compressed air or braking system fluid (similar to the parenthetical keywords given in S5.6.step three.1), is produced regarding brake system. 30 mere seconds following initiation of these ventilation, the supply line is repressurized to your truck decide to try rig (Shape 1). Thirty moments pursuing the initiation of these repressurizing of one’s likewise have line, the leading also have range try ventilated into the conditions. This technique is conducted either by connection and disconnection of your also have line coupling otherwise of the usage of a device hung in the the production range part of the truck shot rig around the also have line coupling.
In the event your automobile is designed to tow a motor vehicle equipped with sky brakes, an effective 50 cubic inch shot tank is connected to the bottom also provide range coupling
S5.six.7 Maximum quantity of prominent diaphragm leakages-particular failure/ Similar number of leakages from the air chamber that has one to diaphragm. In the example of automobile which the option inside S5.6(b) might have been selected, influence the utmost amount of prominent diaphragm leakage-sorts of inability (otherwise equivalent amount of leakage throughout the sky chamber with which has you to definitely diaphragm) according to the strategies set forth in S5.6.7.1 as a result of S5.six.eight.dos.step 3.
S5.six HookupDate reddit.7.step 1.step 1 According to after the procedure, determine the fresh threshold amount of popular diaphragm leaks-type of incapacity (otherwise equivalent quantity of leakages about air chamber with which has that diaphragm) where the new automobile’s parking brake system end up being unreleasable. Which have an initial reservoir program stress of one hundred psi, the engine-turned of, zero applying of the car’s brake system, and you may, in case your vehicle is designed to pull an automible armed with air brakes, a great fifty cubic inch shot tank connected to the also have line coupling, establish a great leakages-style of inability of the well-known diaphragm (otherwise equivalent leakages throughout the heavens chamber containing you to definitely diaphragm). Pertain this new parking brake system by simply making an application actuation of your parking brake handle. Reduce the challenges in most of the car’s reservoirs to no, turn on the fresh motor and allow it so you can sluggish, and permit new challenges regarding automobile’s reservoirs to rise up to it stabilize otherwise before the compressor close-of section try attained. At the time, make a production actuation of vehicle parking brake manage, and find out whether all mechanized mode referred to from inside the S5.6.step three.2 are actuated and you will keep the parking braking system programs with enough parking retardation force to fulfill the minimum abilities given either in S5.6.step one or S5.6.2. Do this process with increasingly decreasing otherwise expanding account (any type of is applicable) away from leakages-variety of diaphragm failures or equivalent leakages, to determine the minimal level of preferred diaphragm leakages-sorts of failure (otherwise equivalent level of leakage on air chamber with which has one diaphragm) where the physical setting referred to in the S5.6.step three.dos are nevertheless actuated and secure the parking brake programs with sufficient vehicle parking retardation pushes in order to meet minimal abilities given in either S5.6.step one or S5.6.2.
S5.6.7.step one.2 Within number of well-known diaphragm leaks-particular failure (otherwise similar amount of leakages about sky chamber that has had that diaphragm) determined in S5.6.eight.1.step one, and ultizing next processes, determine the fresh threshold maximum tank speed (in psi each minute). That have a first reservoir program tension regarding one hundred psi, new engine turned off, zero applying of all car’s brake system and you will, in the event your vehicles was created to pull a car or truck equipped with air brakes, a good 50 cubic inch take to tank attached to the likewise have range coupling, make an application actuation of your own vehicle parking brake handle.
