six.eight.dos.1 According to after the procedure, dictate new threshold amount of prominent diaphragm leakages-type of incapacity (otherwise equivalent number of leakage on the heavens chamber that features one diaphragm) at which the latest vehicle’s vehicle parking brake system be unreleasable. That have a first tank program and provide line stress away from a hundred psi, zero application of all automobile’s brake system, and you may, if the automobile is made to pull an auto armed with sky brake system, a great 50 cubic inch take to reservoir connected to the also provide line coupling, establish an excellent leaks-sorts of failure of one’s well-known diaphragm (otherwise equivalent leaks in the air chamber that contains you to definitely diaphragm). Pressurize the supply range by connecting the new trailer’s front side also have range coupling towards have line part of the truck shot rig (Contour step 1) to your regulator of your trailer test rig put during the 100 psi, to see whether or not every physical form labeled inside the 6.step 3.2 are still actuated and keep the parking brake apps with sufficient parking retardation pushes to generally meet the minimum results given in a choice of six.1 otherwise six.dos. Try this procedure with progressively coming down or expanding account (almost any enforce) regarding leaks-sorts of diaphragm downfalls otherwise similar leakages, to select the minimum amount of prominent diaphragm leakages-type of failure (otherwise comparable number of leaks from the heavens chamber that has you to diaphragm) where every technical setting known inside the six.3.dos are still actuated and you can keep the parking braking system software with plenty of parking retardation pushes to generally meet minimal results given in either six.step 1 or six.2.
six.eight.2.dos From the number of prominent diaphragm leakages-form of failure (or similar jak robi grindr pracД™ amount of leaks on the air chamber that features you to definitely diaphragm) calculated when you look at the 6.eight.2.step 1, and ultizing the following techniques, determine new threshold limit reservoir leakage speed (within the psi per minute). Which have a first tank program and gives range stress regarding a hundred psi, no applying of the automobile’s brakes and you will, if your car was designed to pull a car or truck armed with heavens brake system, a good fifty cubic inches take to tank connected to the bottom also provide line coupling, create a vehicle parking brake application by ventilation the front likewise have line coupling on the environment. Dictate the utmost reservoir leakages rates (during the psi per minute), which is the restrict rates away from reduction of air stress away from the car’s reservoirs that performance then parking brake application.
6.eight.2.3 By using the after the techniques, a good leakage-variety of incapacity of one’s well-known diaphragm (or equivalent leakage on the sky chamber which includes that diaphragm) one contributes to an optimum reservoir leakages rates that’s about three times the newest threshold limit reservoir leaks price computed for the six.eight.2.2. Which have a primary reservoir system and offer range stress away from 100 psi, zero application of the car’s brake system and you may, if your vehicle was designed to tow a car equipped with heavens brakes, a good 50 cubic inch test reservoir linked to the butt likewise have line coupling, make a parking brake app because of the venting leading likewise have range coupling toward conditions. Dictate the utmost tank leakages price (in the psi a minute), which is the restriction price off decrease in air stress away from the automobile’s reservoirs one to performance up coming parking brake software. The degree of common diaphragm leaks-sorts of incapacity (or comparable number of leaks throughout the heavens chamber that has one to diaphragm) with the so it tank leaks speed is the level which is for usage in solution established in the 6(b).
Build a vehicle parking braking system app from the ventilation leading also have range coupling into the environment, and relieve the new demands in all of one’s vehicle’s reservoirs so you can no
eight Crisis brake system having trucks and you may busses. step one, adapts towards the requirements away from seven.step one by way of 7.3. Yet not, this new truck portion of a car or truck transporter shouldn’t have to meet with the road test conditions off eight.step one and you may 7.step 3.
