The thermocouple was additional one cardiovascular system groove
S6.2.cuatro The temperature of every brake was mentioned hitwe hookup by the an individual plug-style of thermocouple installed in the center of the liner body from more heavily stacked shoe or mat just like the found within the Profile 2.
S6.2.5 The pace from braking system musical instrument or disk rotation into the a dynamometer comparable to the speed regarding rotation towards a car or truck at the certain rate are determined from the of course a great tire radius equal towards fixed piled radius specified by tire brand.
Productive estimated luminous contact city ensures that a portion of the projection for the a plane perpendicular on lamp axis of that section of the light-giving off epidermis one delivers light into photometric attempt pattern, and does not are installing hole bosses, response reflector town, beans otherwise tires that shine otherwise establish short regions of enhanced power down to uncontrolled light from quick portion ( 1/2 education distance within decide to try section).
step one.step 1 Sky compressor. An air compressor out of enough capacity to boost air tension when you look at the the supply and you may solution reservoirs out of 85 psi to one hundred psi when the motor is working at automobile maker’s maximum necessary roentgen.p.meters. within a time, when you look at the moments, influenced by new quotient (Genuine tank strength ? 25)/Requisite tank strength.
Repeat the method half a dozen minutes, enhancing the braking system chamber heavens stress by the ten psi whenever
(b) For each and every truck tractor were created towards the otherwise just after , and every single tool automobile are produced with the otherwise immediately after , that is furnished so you’re able to tow another heavens- braked auto, are equipped with a power circuit that is with the capacity of transmitting a breakdown laws throughout the antilock brakes(s) on one or higher towed vehicle(s) (e.g., trailer(s) and you may dolly(ies)) to the trailer Abdominal muscles description lamp in the cab of your towing automobile, and you can shall have the opportinity for union of the electricity routine toward towed auto. Per including vehicle tractor and you will unmarried unit vehicles will even be equipped with an indicator lamp, p needed in step 1.six.2(a), climbed facing plus clear view of brand new rider, that’s activated when the breakdown code circuit described significantly more than receives a laws appearing a stomach breakdown on a single or maybe more towed vehicle(s). The brand new indicator light shall are activated so long as an abs description signal from just one or maybe more towed automobile(s) is available, if the ignition (start) switch is in the “on” (“run”) condition, whether the engine try powering. The latest signal light shall even be triggered given that a out-of light function whenever the ignition are turned to new “on” (“run”) position. The brand new indication lamp is going to be deactivated at the end of this new have a look at off light means until a truck Abs dysfunction code is actually introduce.
S5
(a) As well as the standards from 2.step three.2, for each trailer and truck converter dolly would be armed with a keen outside antilock description sign lamp that meets the needs of 2.step 3.3 (b) courtesy (d).
step 3.step 1 Closing point – autos and you will vehicles. When eliminated half a dozen moments for every single combination of vehicle sorts of, weight, and you can rates given inside 3.step one.step 1, regarding sequence given when you look at the Dining table I, each truck tractor are available on the otherwise after February step 1, 1997, and each unmarried product vehicles are built for the or immediately following March step 1, 1998, shall visit minimum after inside not more than the length given for the Dining table II, mentioned from the part where movement of solution braking system manage begins, without having any area of the auto leaving the new road, and with wheel lockup let merely as follows:
(b) To own automobile built to pull other automobile equipped with sky brake system, the stress throughout the 50-cubic-inches test tank regarded for the step 3.cuatro.1(a) shall, whenever measured in the very first path of your services braking system manage, slide so you can 5 psi inside the not more than 0.75 mere seconds in the case of automobiles and you can busses, step one.ten mere seconds regarding truck converter dollies, and step 1.00 mere seconds when it comes to trailers except that trailer converter dollies.
cuatro.step one.step one After burnishing the brand new brake pursuant so you can S6.2.6, keep up with the brake construction towards the inertia dynamometer. Having an initial braking system temperatures between 125 °F. and two hundred °F., perform a stop out of 50 m.p.h., keeping brake chamber sky stress at the a reliable 20 psi. Assess the mediocre torque exerted by braking system from the time the specified sky pressure is actually reached up until the braking system ends and separate of the fixed stacked tire radius given from the tire company to select the retardation push. After each and every end, switch new braking system musical instrument otherwise disc through to the heat of your braking system drops so you can ranging from 125 °F. and 200 °F.
(a) Except since considering during the six(b) and you can six(c), per vehicle aside from a truck converter dolly shall enjoys a good vehicle parking brake system that in requirements out of S6.step 1 match the needs of:
6.step three.cuatro The fresh vehicle parking braking system chamber challenges to possess 6.step three.step 1 and you can 6.3.dos are determined the following. Getting cars and you can busses, having a first tank program stress away from one hundred psi and you will, when the built to tow an automobile armed with heavens brake system, which have good 50 cubic inches decide to try reservoir linked to the have line coupling, one single leakage sort of incapacity, in any most other brakes, from an associate designed to have compressed-air otherwise brake fluid (consistent with the parenthetical words given from inside the 6.3.1), is introduced on brake system. This new parking brake manage is actually actuated as well as the demands from the vehicle’s parking braking system spaces try measured around three mere seconds after that actuation is established. To possess trailers, on the have range very first pressurized to help you 100 psi with the supply range portion of the trailer attempt rig (Profile 1) and you will, in the event the designed to pull an automible armed with sky brake system, which have an excellent fifty cubic inches shot tank attached to the bottom also have range coupling, one solitary leakage variety of incapacity, in every almost every other brake system, from an associate built to consist of compressed air or brake liquid (consistent with the parenthetical words specified in the 6.3.1), is actually introduced in the brake system. The leading supply range coupling are vented with the ambiance and you will the new demands from the vehicle’s parking braking system compartments was mentioned around three seconds up coming venting is established.
6.six.cuatro To possess trailers, having first conditions because given within the six.6.5, the vehicle parking brakes can be capable of meeting minimal show specified in a choice of six.step one otherwise six.2, that have people solitary leakages-sorts of failure, in just about any almost every other brakes, from a part built to incorporate compressed-air otherwise brake liquid (similar to the parenthetical statement given for the six.step 3.1), after the test series specified when you look at the 6.six.six.
nine Last review. Always check the service brake system on the updates off changes and on the brake indicator display screen prior to step one.8 and you will 2.2.
S6.step one.ten From inside the a test apart from a fixed parking take to, a truck tractor try looked at from the its GVWR from the coupling it in order to an unbraked flatbed partial-trailer (hereafter, manage truck) as the given into the S6.1.ten.dos to help you S6.1.10.4.
S6.2.step three Sky in the ambient weather is led evenly and continuously more than the newest brake instrument otherwise disk on a velocity regarding dos,200 feet each and every minute.
