The front also have line coupling was ventilated into the atmosphere

Apply the parking brake system through an application actuation of vehicle parking brake manage

S5.six.six.5 The first requirements for S5.6.6.cuatro are as follows: The tank system and gives range was pressurized to a hundred psi, utilising the also provide range part of the truck shot rig (Shape step 1).

S5.6.six.six The test sequence for S5.six.6.4 is as comes after. Any unmarried leakages kind of incapacity, in virtually any most other brake system, away from an associate designed to include compressed-air or brake water (similar to the parenthetical terms specified from inside the S5.six.3.1), is put in the brake system. Thirty mere seconds following initiation of these venting, the production range is actually repressurized on trailer try rig (Profile 1). 30 moments following the initiation of these repressurizing of your own also have line, the front also have line is actually vented towards the surroundings. This process is completed both from the commitment and disconnection of one’s supply range coupling otherwise from the usage of a device hung inside the supply line part of the trailer sample rig near the also provide range coupling.

S5.6.7 Restriction quantity of common diaphragm leakages-types of inability/ Equivalent level of leakages from the heavens chamber with one diaphragm. In the case of vehicle whereby the option when you look at the S5.6(b) could have been selected, dictate the most amount of prominent diaphragm leakages-type of failure (otherwise similar number of leakages about sky chamber that has you to definitely diaphragm) according to measures set forth from inside the S5.six.7.step 1 through S5.six.eight.2.step 3.

In the event the vehicles was designed to pull a vehicle equipped with air brakes, a great 50 cubic inches take to tank was connected to the butt also provide range coupling

S5.six.seven.1.step 1 With regards to the following process, dictate this new endurance amount of preferred diaphragm leakage-kind of inability (otherwise equivalent quantity of leakage on heavens chamber with you to definitely diaphragm) from which the new car’s parking brakes end up being unreleasable. Having an initial reservoir system tension out of 100 psi, the latest engine-turned away from, no applying of the automobile’s brakes, and you can, when your car is made to pull a motor vehicle armed with sky brake system, good fifty cubic inch take to tank linked to the also provide line coupling, expose an effective leakages-kind of incapacity of the common diaphragm (otherwise similar leaks in the heavens chamber that has had that diaphragm). Slow down the demands throughout of vehicle’s reservoirs so you can zero, activate this new system and permit they in order to lazy, and invite new demands on car’s reservoirs to increase until they balance out or until the compressor shut-regarding part is actually achieved. During the time, build a launch actuation of your own parking braking system handle, and see whether all the mechanical form referred to in the S5.six.step 3.2 continue to be actuated and you can keep the vehicle parking braking system applications with sufficient parking retardation push to meet up with minimal abilities given in both S5.6.1 or S5.six.2. Do this processes having more and more decreasing or expanding account (any applies) of leakages-sorts of diaphragm downfalls or similar leaks, to determine the minimal level of well-known diaphragm leakages-sorts of failure (or comparable level of leakages throughout the heavens chamber that has had one diaphragm) at which all the mechanical jak uЕјywaД‡ good grief means known inside the S5.6.step 3.dos continue to be actuated and you will hold the vehicle parking brake software with plenty of parking retardation forces to satisfy the minimum abilities specified in either S5.6.step 1 or S5.six.2.

S5.6.7.step one.2 At the quantity of preferred diaphragm leakage-particular failure (or comparable number of leaks on the sky chamber that features one diaphragm) determined when you look at the S5.6.7.step one.1, and ultizing next process, influence the brand new threshold restriction tank speed (for the psi each minute). Having a primary tank program tension regarding 100 psi, the new engine-turned of, no applying of the vehicle’s brake system and you may, in the event your vehicles was created to tow an auto equipped with heavens brakes, a 50 cubic inches test tank linked to the likewise have line coupling, make an application actuation of your parking braking system handle. Influence the most reservoir leakages rates (for the psi each and every minute), which is the maximum price away from decrease in sky tension out-of the car’s reservoirs one show then vehicle parking brake application.
