6.7.2.step 1 With respect to the following the processes, determine the newest endurance level of prominent diaphragm leaks-type of inability (otherwise equivalent number of leakage about heavens chamber that has had that diaphragm) of which this new vehicle’s parking brake system feel unreleasable. With a primary tank system and supply line pressure out of 100 psi, zero application of some of the car’s brake system, and you can, in case your auto is made to tow a car equipped with air brakes, good fifty cubic inch test reservoir connected to the also provide line coupling, expose an effective leakage-types of incapacity of the preferred diaphragm (or equivalent leakage throughout the sky chamber which has had one to diaphragm). Pressurize the supply line by the linking the fresh trailer’s side supply range coupling towards the also provide anxiety chat room italian range part of the trailer shot rig (Contour 1) on the regulator of trailer take to rig put on 100 psi, and discover whether every technical mode described in six.step three.dos are still actuated and you can secure the parking braking system programs with enough parking retardation forces to meet up the minimum results specified in either 6.step one or 6.2. Repeat this processes that have increasingly decreasing otherwise increasing profile (whatever can be applied) of leakage-style of diaphragm problems or comparable leakage, to find the minimal level of common diaphragm leaks-variety of failure (or comparable number of leaks on heavens chamber who has you to definitely diaphragm) where all the technical setting labeled from inside the six.step three.dos continue to be actuated and you will hold the parking brake programs with enough vehicle parking retardation forces in order to satisfy the minimum results given in a choice of six.step 1 otherwise 6.2.
Build a parking braking system app from the venting leading likewise have range coupling on ambiance, and reduce the fresh new challenges in all of your automobile’s reservoirs in order to no
six.7.dos.2 Within quantity of popular diaphragm leakage-sorts of failure (otherwise comparable amount of leakages in the air chamber which has you to definitely diaphragm) computed in 6.7.dos.step one, and making use of next processes, influence new endurance restrict tank leakage price (during the psi a minute). Which have an initial reservoir system and offer range tension out-of one hundred psi, zero application of all car’s brakes and you can, in case the vehicles was designed to pull an automobile armed with sky brake system, a good 50 cubic inch take to reservoir connected to the butt supply line coupling, create a parking brake application because of the ventilation the leading likewise have line coupling on the ambiance. Dictate the utmost reservoir leakages price (during the psi for each minute), the restrict speed away from reduced amount of heavens pressure out-of some of the automobile’s reservoirs one performance upcoming parking braking system software.
six.eight.2.step three By using the following techniques, an excellent leakages-type of incapacity of the well-known diaphragm (otherwise similar leaks on heavens chamber that has one to diaphragm) one to contributes to an optimum tank leakage rates which is around three minutes the brand new endurance limit tank leakages rates computed in six.seven.dos.2. With a first reservoir program and gives line pressure away from 100 psi, no application of any of the car’s brakes and, if the vehicles is designed to tow an auto armed with heavens brake system, an effective 50 cubic inches decide to try reservoir linked to the rear supply line coupling, generate a vehicle parking brake application from the venting leading supply line coupling on the environment. Influence the maximum reservoir leaks price (for the psi for each minute), the maximum rate out-of reduced total of sky stress off all vehicle’s reservoirs one efficiency up coming vehicle parking braking system app. The amount of preferred diaphragm leaks-type of incapacity (otherwise comparable amount of leaks throughout the sky chamber which has one diaphragm) from the which reservoir leakages rate is the level that’s to be used within the option set forth from inside the six(b).
7 Emergency brake system having autos and you can vehicles. step one, adjusts towards requirements out-of seven.1 by way of eight.step 3. But not, the newest vehicle portion of an automible transporter need not meet the road test conditions off eight.1 and you can seven.3.
