Leading also provide line coupling was vented to the ambiance

At the time, generate a release actuation of one’s parking brake handle, to check out if or not all of the mechanized setting referred to when you look at the S5

S5.6.6.5 The initial requirements for S5.6.six.4 are listed below: The new tank program and offer range try pressurized so you’re able to one hundred psi, by using the have range part of the trailer sample rig (Contour step 1). When your automobile was designed to tow a car armed with air brake system, an effective 50 cubic inch decide to try tank are linked to the rear also provide line coupling.

Thirty moments following initiation of such venting, the production line is repressurized with the truck test rig (Profile step 1)

S5.six.six.6 The exam series to own S5.six.six.4 can be follows. Any single leaks kind of incapacity, in just about any almost every other brakes, from a member made to have compressed-air or brake liquid (similar to the parenthetical words given within the S5.6.step three.1), is actually lead on the brakes. Thirty mere seconds following the initiation of these repressurizing of the also have range, the leading supply line try vented to your conditions. This procedure is performed possibly because of the commitment and you can disconnection of the have line coupling otherwise of the entry to a valve installed from inside the the production range part of the truck test rig nearby the supply line coupling.

S5.six.7 Restrict number of common diaphragm leakage-sort of failure/ Equivalent number of leakages in the sky chamber containing that diaphragm. In the example of vehicles which the option into the S5.6(b) might have been picked, dictate the maximum amount of well-known diaphragm leakages-form of inability (or equivalent amount of leakages on the heavens chamber which has had you to definitely diaphragm) with regards to the steps set forth from inside the S5.six.eight.1 because of S5.

S5.six.seven.step one.step one With respect to the pursuing the processes, determine the latest threshold quantity of well-known diaphragm leaks-types of incapacity (otherwise similar amount of leaks on sky chamber that features one to diaphragm) from which the new automobile’s vehicle parking brake system end up being unreleasable. With an initial tank system tension away from one hundred psi, the fresh new engine-turned regarding, no applying of the automobile’s brake system, and you will, in case the automobile is made to tow an automible equipped with sky brakes, a beneficial 50 cubic inch shot tank attached to the also provide line coupling, introduce a great leakages-type of incapacity of your prominent diaphragm (or equivalent leakage throughout the heavens chamber which has had that diaphragm). Incorporate the vehicle parking brakes through an application actuation of your vehicle parking brake handle. Slow down the demands in most of the vehicle’s reservoirs to help you zero, trigger the fresh new engine and enable it so you’re able to sluggish, and enable the latest challenges in the vehicle’s reservoirs to increase until they stabilize or up until the compressor shut-out of section is reached. six.step three.2 will always be actuated and contain the vehicle parking brake software with enough vehicle parking retardation force to meet the minimum efficiency given either in S5.6.1 otherwise S5.6.2. Repeat this techniques having progressively decreasing or growing account (any type of is applicable) from leakage-form of diaphragm downfalls or comparable leakages, to choose the lowest number of well-known diaphragm leaks-method of failure (otherwise comparable quantity of leaks from the air chamber containing one to diaphragm) from which all the technical mode labeled inside the S5.six.step three.2 will still be actuated and keep the parking braking system apps with enough parking retardation forces to fulfill minimal show given in both S5.six.1 or S5.six.dos.

S5.six.7.1.dos From the quantity of well-known diaphragm leaks-type inability (or similar number of leakage on https://datingmentor.org/tr/guyspy-inceleme/ the air chamber who has you to diaphragm) calculated when you look at the S5.6.7.1.step one, and utilizing another techniques, dictate this new tolerance limitation reservoir rates (within the psi a minute). That have a primary reservoir program stress from one hundred psi, brand new engine turned regarding, zero application of the vehicle’s brake system and you can, in case the auto was designed to tow a car armed with sky brake system, an effective fifty cubic inch sample reservoir linked to the likewise have line coupling, make an application actuation of the vehicle parking braking system manage. Determine the utmost tank leakages price (when you look at the psi for each minute), the limitation rate off reduction of air stress from the automobile’s reservoirs that results up coming vehicle parking braking system app.
