During the time, create a production actuation of your vehicle parking braking system control, and determine whether or not all the technical mode referred to within the S5
S5.6.six.5 The original standards having S5.six.6.4 are listed below: New tank system and supply range are pressurized to help you 100 psi, utilizing the also provide line portion of the truck take to rig (Contour 1). When your automobile was created to pull an automible armed with air brake system, an effective fifty cubic inches sample tank are linked to the rear supply range coupling.
30 seconds pursuing the initiation of these ventilation, the production range are repressurized for the truck take to rig (Figure 1)
S5.six.6.six The test series to possess S5.6.six.cuatro is as uses. One single leaks type of failure, in virtually any other brake system, off a member built to have compressed air otherwise braking system water (consistent with the parenthetical words specified when you look at the S5.six.step 3.1), are lead about brakes. 30 mere seconds after the initiation of these repressurizing of your own supply line, leading have line are ventilated on the ambiance. This method is conducted either from the relationship and disconnection of one’s have line coupling otherwise by the the means to access a valve hung within the the production range portion of the trailer sample rig nearby the have line coupling.
S5.six.7 Maximum level of well-known diaphragm leakages-type incapacity/ Similar quantity of leakages on sky chamber which has you to diaphragm. When it comes to car wherein the possibility in S5.6(b) might have been decided, dictate maximum amount of preferred diaphragm leakages-particular inability (or equivalent quantity of leakage on the sky chamber that has you to definitely diaphragm) with regards to the measures established from inside the S5.six.7.1 thanks to S5.6.eight.2.step three.
S5.six.eight.1.1 Depending on the pursuing the procedure, determine brand new tolerance number of prominent diaphragm leakage-sorts of inability (or comparable amount of leaks about sky chamber with one diaphragm) from which the automobile’s vehicle parking brake system end up being unreleasable. Having an initial tank system stress of 100 psi, the engine-turned away from, no applying of some of the car’s brakes, and you can, if for example the auto was designed to tow a motor vehicle equipped with heavens brake system, an effective fifty cubic inch test reservoir linked to the also provide range coupling, establish a great leaks-sorts of incapacity of your own popular diaphragm (or equivalent leaks from the air chamber which has had you to definitely diaphragm). Pertain the brand new parking brake system by making a credit card applicatoin actuation of parking braking system manage. Slow down the pressures in most of your car’s reservoirs so you can zero, turn on brand new motor and allow it so you can sluggish, and permit the brand new pressures throughout the automobile’s reservoirs to rise up to they stabilize or up until the compressor closed-out-of area was attained. six.step 3.2 are still actuated and you will keep the parking brake apps with plenty of parking retardation force to meet up the minimum efficiency specified either in S5.six.step 1 otherwise S5.6.dos. escort girls in Irvine Try this procedure with more and more coming down or expanding membership (any enforce) out-of leaks-sorts of diaphragm disappointments otherwise comparable leaks, to determine the lowest amount of preferred diaphragm leaks-particular inability (otherwise equivalent amount of leakages from the air chamber which includes you to diaphragm) of which most of the technical function regarded for the S5.six.step 3.2 continue to be actuated and you will hold the parking braking system programs with sufficient parking retardation forces meet up with minimal show specified in both S5.six.step one or S5.6.dos.
S5.6.seven.step one.dos In the quantity of well-known diaphragm leakages-method of failure (or similar quantity of leakages in the heavens chamber that features one diaphragm) computed from inside the S5.6.7.step one.step one, and using another process, determine the newest tolerance maximum reservoir rates (inside psi per minute). With a primary reservoir program stress away from 100 psi, this new engine-turned of, no applying of any of the automobile’s brakes and, in case the automobile is made to tow an auto equipped with air brakes, an effective 50 cubic inches shot tank attached to the also have line coupling, make an application actuation of your own parking braking system control. Influence the maximum reservoir leakage speed (in psi a minute), the restrict speed of reduction of sky tension of any of the car’s reservoirs one to show after that parking brake software.
