Apply the new vehicle parking brakes through an application actuation of parking braking system handle

S5.6.six.5 The first conditions to have S5.six.six.cuatro are listed below: The fresh tank system and provide range was pressurized so you can a hundred psi, utilising the have line portion of the trailer sample rig (Profile 1).

S5.six.six.six The test series having S5.six.six.4 is just as observe. People solitary leaks types of incapacity, in just about any almost every other brake system, off a part built to contain compressed-air or brake liquid (similar to the parenthetical phrase specified during the S5.6.step three.1), was delivered throughout the brake system. 30 seconds pursuing the initiation of such ventilation, the production line are repressurized to your trailer shot rig (Shape step 1). Thirty seconds pursuing the initiation of these repressurizing of your supply range, the leading have line are vented to the ambiance. This process is performed both by commitment and disconnection of your also provide range coupling or because of the access to a valve hung from inside the the supply line portion of the trailer attempt rig around the also provide line coupling.

S5.six.eight Restrict amount of common diaphragm leakage-sorts of incapacity/ Comparable number of leakage about heavens chamber that contains you to definitely diaphragm. In the example of auto where the option inside the S5.6(b) might have been decided on, influence the hookup MOBIELE SITE utmost number of well-known diaphragm leakages-kind of inability (otherwise equivalent level of leakages regarding air chamber that contains one to diaphragm) with regards to the methods established within the S5.6.eight.step one courtesy S5.6.seven.dos.3.

In the event the vehicles is designed to pull a car armed with sky brakes, an effective 50 cubic inches take to tank are attached to the butt supply range coupling

S5.6.seven.step one.step one According to after the techniques, dictate the new endurance level of prominent diaphragm leakage-form of failure (or similar number of leakages throughout the air chamber who has one diaphragm) from which this new automobile’s parking brake system become unreleasable. With an initial tank program tension from one hundred psi, the fresh new engine turned from, zero application of any of the car’s brake system, and you may, whether your car was created to tow a motor vehicle armed with air brakes, a great fifty cubic inches sample tank linked to the supply line coupling, establish a leakage-kind of incapacity of common diaphragm (or similar leakage from the heavens chamber that has one diaphragm). Reduce the demands throughout of your automobile’s reservoirs so you’re able to no, trigger the motor and enable they in order to idle, and enable the latest challenges regarding vehicle’s reservoirs to rise up to it balance otherwise up until the compressor shut-regarding part was reached. During the time, make a release actuation of the parking brake control, to check out if or not all the mechanized function regarded from inside the S5.6.step 3.dos remain actuated and you will keep the vehicle parking braking system apps with plenty of parking retardation force to meet up the minimum efficiency given in either S5.six.step one otherwise S5.six.dos. Try this procedure with progressively coming down or growing accounts (any type of applies) regarding leakages-kind of diaphragm disappointments otherwise similar leaks, to select the minimum quantity of popular diaphragm leaks-type of inability (or comparable level of leaks about air chamber with which has that diaphragm) from which all of the technical means labeled from inside the S5.six.step three.dos will always be actuated and you will contain the vehicle parking brake applications with sufficient vehicle parking retardation forces meet up with minimal results given in either S5.6.step 1 otherwise S5.6.dos.

S5.six.7.step one.dos During the quantity of prominent diaphragm leakages-type of inability (otherwise similar amount of leakage about sky chamber that has that diaphragm) determined in the S5.six.eight.step 1.step 1, and using the next procedure, dictate the new endurance restriction reservoir rates (into the psi for each minute). Which have an initial tank program stress away from 100 psi, the fresh engine-turned out of, no application of all automobile’s brake system and you can, should your car is made to tow a car armed with sky brakes, an excellent 50 cubic inches decide to try tank attached to the also provide range coupling, make an application actuation of vehicle parking braking system manage. Dictate maximum tank leaks rates (during the psi per minute), the restrict price out of reduction of sky tension out of any of the vehicle’s reservoirs one to efficiency then vehicle parking brake app.
