Influence the most tank leakage rates (in the psi each and every minute), which is the limit rate out of reduction of sky tension out of some of the car’s reservoirs you to performance upcoming vehicle parking brake application
S5.six.six.5 The first standards to possess S5.six.six.4 are as follows: Brand new reservoir system and provide line was pressurized to help you 100 psi, utilizing the supply line part of the trailer take to rig (Profile step one).
S5.six.six.6 The exam series having S5.six.six.cuatro can be as employs. One single leaks sort of failure, in any almost every other brakes, from a part made to incorporate compressed air otherwise brake liquid (similar to the parenthetical keywords given into the S5.six.step three.1), is actually produced about brakes. 30 seconds after the initiation of such ventilation, the supply range was repressurized on the trailer sample rig (Figure 1). Thirty moments adopting the initiation of such repressurizing of the also provide range, the front also have range try ventilated on environment. This procedure is conducted sometimes of the partnership and you will disconnection of one’s supply range coupling otherwise by use of a valve hung inside the supply line part of the truck take to rig around the likewise have range coupling.
In case your vehicles is made to tow an automobile armed with air brake system, a 50 cubic inches attempt tank try attached to the buttocks also have line coupling
S5.six.eight Limit number of common diaphragm leaks-sort of failure/ Equivalent level of leakages about air chamber with which has you to definitely diaphragm. When it comes to vehicle in which the option inside the S5.6(b) could have been opted, influence the maximum level of well-known diaphragm leaks-type of incapacity (otherwise similar number of leakages regarding sky chamber that features one to diaphragm) according to the strategies set forth from inside the S5.six.seven.step 1 courtesy S5.6.eight.dos.3.
S5.six.eight.step one.1 According to after the processes, dictate the new tolerance quantity of prominent diaphragm leaks-variety of incapacity (otherwise similar amount of leaks on air chamber which has that diaphragm) where brand new vehicle’s vehicle parking brake system become unreleasable. That have a primary reservoir program tension out-of a hundred psi, the newest engine-turned out-of, datingmentor.org/pl/geek-randki/ no application of some of the vehicle’s brakes, and, in case your vehicle was created to tow an auto armed with sky brake system, good fifty cubic inches try reservoir connected to the likewise have range coupling, present a leakages-sort of failure of your popular diaphragm (otherwise comparable leakage throughout the sky chamber that has one to diaphragm). Apply this new parking brake system by simply making a loan application actuation of parking braking system handle. Reduce the challenges in all of your car’s reservoirs in order to no, stimulate the fresh new system and enable it in order to idle, and permit the brand new demands about car’s reservoirs to go up until it balance or until the compressor shut-off area is actually hit. At that time, create a launch actuation of your vehicle parking brake handle, to discover if all of the physical mode regarded inside the S5.six.step 3.2 are nevertheless actuated and you can support the parking brake apps with enough parking retardation force in order to meet the minimum performance specified in either S5.six.step 1 otherwise S5.6.2. Try this techniques having more and more coming down otherwise increasing levels (any sort of is applicable) of leaks-form of diaphragm failures or comparable leaks, to select the minimal level of prominent diaphragm leakage-method of failure (or equivalent quantity of leakage in the heavens chamber that contains that diaphragm) at which all of the technical function described inside S18.104.22.168 continue to be actuated and you will support the vehicle parking brake software with plenty of vehicle parking retardation pushes meet up with the minimum efficiency given in a choice of S5.6.1 or S5.six.dos.
S5.six.seven.1.dos At number of common diaphragm leakages-style of incapacity (otherwise equivalent level of leakages on heavens chamber which includes you to definitely diaphragm) computed within the S5.6.eight.step one.step 1, and utilizing another techniques, determine the latest endurance restrict reservoir price (within the psi per minute). With an initial reservoir program tension regarding a hundred psi, the fresh new engine-turned away from, zero applying of the automobile’s brakes and, should your automobile was created to tow a motor vehicle equipped with heavens brake system, a great 50 cubic inches test reservoir attached to the likewise have line coupling, make an application actuation of your own parking brake manage.
