S6.dos.4 Heat of each and every braking system are measured by a single plug-kind of thermocouple installed in the exact middle of the liner body away from the absolute most heavily stacked footwear or mat because the found in Contour dos.
S6.dos.5 The rate out-of brake musical instrument otherwise disc rotation toward a beneficial dynamometer corresponding to the pace from rotation toward a car on confirmed speed is actually calculated from the assuming a beneficial tire distance equivalent towards static stacked distance specified by the tire company.
Effective estimated luminous contact area ensures that an element of the projection into an airplane perpendicular to the light axis of these portion of the white-emitting body one sends white for the photometric shot pattern, and won’t tend to be mounting hole bosses, response reflector city, beans otherwise rims that shine otherwise build short regions of enhanced strength right down to uncontrolled white out-of small portion ( 1/dos education radius inside the test area).
1.1 Sky compressor. An atmosphere compressor from enough capability to boost heavens pressure when you look at the the supply and service reservoirs regarding 85 psi to a hundred psi when the engine is actually operating during the vehicles manufacturer’s limitation necessary r.p.yards. inside a period, during the moments, determined by the brand new quotient (Genuine tank strength ? 25)/Expected reservoir capabilities.
Recite the procedure half a dozen moments, enhancing the braking system chamber sky pressure from the ten psi when
(b) For every single truck tractor are made towards the otherwise immediately following , each single unit car are produced to your or once , that is furnished in order to tow various other heavens- braked auto, will likely be armed with a power routine that’s ready shipping a breakdown signal from the antilock brakes(s) on a single or higher towed automobile(s) (e.g., trailer(s) and you can dolly(ies)) on the truck Stomach breakdown light throughout the taxi of one’s towing automobile, and should feel the opportinity for union on the electric routine into towed vehicles. For each for example truck tractor and you can solitary equipment automobile shall even be armed with indicative lamp, p needed in step one.six.2(a), mounted before and in clear look at this new driver, that’s triggered as soon as the dysfunction code routine discussed significantly more than get a code demonstrating an abdominal muscles breakdown using one or maybe more towed vehicle(s). New signal lamp shall continue to be triggered as long as an abs description code from just one or higher towed vehicles(s) can be obtained, as soon as the ignition (start) button is in the “on” (“run”) position, if the engine try powering. The brand new indicator lamp should additionally be activated due to the fact a away from lamp mode once the ignition are looked to the new “on” (“run”) condition. The fresh new indicator lamp is deactivated at the end of the latest take a look at regarding lamp setting until a trailer Abdominal muscles breakdown laws are introduce.
S5
(a) Plus the requirements out of dos.step three.2, for each and every trailer and you can truck converter dolly shall be equipped with an exterior antilock breakdown indicator light that suits the needs of 2.3.step 3 (b) owing to (d).
3.step 1 Closing length – automobiles and you may buses. When averted half a dozen moments for each mixture of vehicles sort of, pounds, and you will speed specified when you look at the 3.1.step 1, on series given in the Dining table I, for each and every vehicle tractor are designed to your otherwise immediately after March 1, 1997, and each 
single product car are produced on otherwise once March 1, 1998, shall stop at the very least after within the not more than the distance given in the Table II, mentioned on part where direction of service brake handle initiate, without the an element of the vehicle leaving the new highway, sufficient reason for controls lockup permitted just the following:
(b) To have car built to tow various other vehicle armed with air brake system, the pressure in the fifty-cubic-inches attempt tank known during the 3.4.1(a) should, when measured throughout the very first way of your own provider braking system control, fall to 5 psi inside only 0.75 mere seconds when it comes to autos and busses, step one.ten mere seconds when it comes to trailer converter dollies, and step one.00 moments in the example of trailers aside from truck converter dollies.
cuatro.step 1.step 1 Just after burnishing the fresh brake pursuant to help you S6.dos.six, retain the brake installation into the inertia dynamometer. Which have a primary braking system heat anywhere between 125 °F. and you can 200 °F., make a stop out-of fifty m.p.h., maintaining braking system chamber heavens tension on a reliable 20 psi. Gauge the average torque exerted from the brake since that time the desired air pressure try reached through to the brake concludes and you will divide because of the static stacked tire distance given because of the tire manufacturer to choose the retardation push. After each and every stop, switch the new brake guitar otherwise disc before the temperature of your braking system falls to anywhere between 125 °F. and you may 2 hundred °F.
(a) But due to the fact provided in 6(b) and you will six(c), each vehicle other than a trailer converter dolly shall features a great parking brake system that underneath the standards away from S6.1 match the requirements of:
6.3.4 The fresh new parking braking system chamber demands for 6.step three.1 and 6.3.2 decided below. Having cars and busses, with a first reservoir program pressure out of a hundred psi and, when the designed to pull an automobile equipped with sky brake system, with a beneficial 50 cubic inch try reservoir connected to the have range coupling, any single leaks kind of incapacity, in virtually any other brake system, of a member built to include compressed air or brake fluid (consistent with the parenthetical statement given in the six.step three.1), is actually produced in the brake system. New parking braking system handle try actuated as well as the demands throughout the vehicle’s vehicle parking braking system spaces is actually measured three seconds upcoming actuation is established. To possess trailers, for the also provide range 1st pressurized in order to 100 psi making use of the have range part of the truck decide to try rig (Figure 1) and, if the made to tow a car or truck equipped with heavens brake system, with an effective fifty cubic inches sample tank connected to the bottom have range coupling, any single leaks sort of inability, in virtually any most other brakes, off an associate designed to contain compressed-air or brake liquid (consistent with the parenthetical terms specified in the six.step 3.1), was brought throughout the brake system. Leading supply line coupling was ventilated to your conditions and the fresh demands throughout the vehicle’s vehicle parking brake spaces are mentioned three mere seconds then ventilation is set up.
6.6.4 Having trailers, having very first criteria since specified when you look at the six.6.5, the new parking brakes would be with the capacity of appointment the minimum performance given in a choice of 6.step one or six.dos, which have one solitary leaks-type incapacity, in almost any other brake system, out of a part made to incorporate compressed-air otherwise brake water (similar to the parenthetical terms specified into the six.step 3.1), at the end of the test succession given into the six.6.6.
9 Finally assessment. Search the service brakes toward position of adjustment and into the braking system indicator display screen in line with step 1.8 and dos.dos.
S6.1.ten In a test aside from a fixed vehicle parking take to, a trailer tractor is looked at on their GVWR of the coupling they to help you an enthusiastic unbraked flatbed semi-trailer (hereafter, manage trailer) due to the fact given in S6.1.ten.dos so you can S6.1.ten.cuatro.
S6.2.step 3 Heavens during the ambient weather is led uniformly and you will continuously more the newest brake musical instrument otherwise disk on a speed regarding dos,two hundred ft each minute.
