Apply the vehicle parking brake system by making a loan application actuation of one’s parking braking system handle

S5.six.6.5 The initial standards to own S5.6.6.4 are as follows: The brand new tank system and offer line is actually pressurized so you’re able to 100 psi, utilising the likewise have range part of the truck decide to try rig (Contour step one).

S5.6.6.6 The test series getting S5.6.6.4 can be employs. One single leakages particular failure, in just about any other brakes, out-of a part built to incorporate compressed air or brake fluid (similar to the parenthetical words specified during the S5.six.step three.1), is delivered about brakes. 30 moments following the initiation of these venting, the production line try repressurized with the trailer try rig (Figure 1). Thirty seconds following initiation of these repressurizing of your own likewise have range, leading also have line try vented towards the environment. This method is conducted sometimes of the partnership and disconnection of the also provide range coupling or because of the the means to access a valve installed when you look at the the production line portion of the trailer try rig near the also provide line coupling.

S5.six.7 Maximum amount of common diaphragm leakage-kind of failure/ Comparable amount of leaks on the sky chamber that contains you to definitely diaphragm. When it comes to automobile whereby the possibility inside the S5.6(b) could have been decided on, influence the maximum amount of prominent diaphragm leakage-form of inability (or equivalent number of leaks in the sky chamber with one to diaphragm) according to procedures established when you look at the S5.6.seven.step one due to S5.six.eight.2.3.

In case the vehicle was created to tow a car equipped with sky brake system, good 50 cubic inch take to tank try linked to the bottom likewise have range coupling

S5.six.eight.1.step 1 According to following the techniques, dictate new tolerance level of popular diaphragm leakage-kind of incapacity (or similar number of leaks in the sky chamber containing that diaphragm) from which new automobile’s parking brakes be unreleasable. Having an initial reservoir program pressure out of one hundred psi, the new engine-turned off, no applying of some of the car’s brake system, and you can, in the event the vehicle is made to tow an auto armed with sky brakes, an excellent 50 cubic inches decide to try reservoir attached to the supply line coupling, establish a great leakages-variety of inability of the preferred diaphragm (otherwise equivalent leaks throughout the air chamber that contains one to diaphragm). Slow down the pressures in all of the car’s reservoirs to zero, turn on the latest system and allow it to idle, and enable the newest challenges in the automobile’s reservoirs to rise until they balance or up until the compressor shut-out-of area is actually achieved. At the time, create a release actuation of parking brake handle, and determine whether most of the physical form regarded when you look at the S5.six.step 3.dos are actuated and you will support the parking braking system applications with sufficient parking retardation push to get to know minimal results specified in both S5.6.step one or S5.six.dos. Гјcretsiz geek tanД±Еџma uygulamalarД± Repeat this procedure which have increasingly decreasing or broadening account (whatever enforce) out-of leakage-types of diaphragm disappointments otherwise comparable leaks, to select the minimum number of prominent diaphragm leakages-sort of failure (otherwise equivalent quantity of leaks from the sky chamber which has one to diaphragm) where the physical means known in the S5.six.3.2 remain actuated and contain the vehicle parking brake applications with plenty of parking retardation pushes to satisfy minimal performance given in either S5.6.1 otherwise S5.6.2.

S5.6.7.1.2 In the level of prominent diaphragm leaks-form of incapacity (otherwise comparable amount of leaks throughout the heavens chamber that has had you to definitely diaphragm) computed for the S5.6.seven.step 1.step 1, and making use of another procedure, determine the fresh endurance limit reservoir price (within the psi for each minute). Which have an initial reservoir system stress from one hundred psi, this new engine turned away from, no applying of any of the car’s brake system and you can, in the event the car was designed to tow an automobile armed with heavens brake system, an effective fifty cubic inch decide to try tank linked to the likewise have line coupling, apply actuation of the vehicle parking brake handle. Dictate the maximum reservoir leaks rates (when you look at the psi for each minute), the restriction rate of reduced total of sky stress away from all automobile’s reservoirs you to definitely abilities after that parking brake application.
