S6.dos.cuatro The heat each and every brake is actually measured by one plug-kind of thermocouple strung in the exact middle of the liner facial skin regarding the absolute most greatly piled shoe otherwise mat because shown into the Profile 2.
S6.2.5 The speed regarding brake musical instrument or disc rotation into an effective dynamometer comparable to the rate regarding rotation on an automobile during the a given price try computed of the assuming an excellent tire radius equivalent to your static stacked distance given by tire brand name.
Energetic estimated luminous lens area means that a portion of the projection to your an airplane perpendicular for the light axis of these section of your light-giving off body you to definitely sends white on photometric shot trend, and won’t are installing gap employers, response reflector city, beads or rims that can sparkle otherwise produce short regions of increased strength down to out of control light out of small section ( 1/dos studies radius inside the try point).
1.1 Sky compressor. An atmosphere compressor out of sufficient capability to boost air stress in the supply and you may service reservoirs out-of 85 psi to help you one hundred psi if motor try functioning during the automobile manufacturer’s restrict required r.p.yards. inside a time, for the mere seconds, dependent on the fresh quotient (Genuine reservoir capacity ? 25)/Required reservoir skill.
Recite the procedure six minutes, increasing the imeetzu nedir braking system chamber heavens pressure from the 10 psi anytime
(b) Per truck tractor are manufactured to the or immediately after , and each single unit vehicle are built towards otherwise immediately following , which is furnished to tow various other sky- braked car, shall be equipped with a power circuit that’s with the capacity of sending a fail laws from the antilock brakes(s) using one or even more towed car(s) (age.grams., trailer(s) and you can dolly(ies)) to your truck Abs breakdown light about cab of pulling vehicles, and you can will feel the method for union from the electronic circuit on the towed auto. For every single like vehicle tractor and you can single unit auto should even be equipped with indicative lamp, p required in step 1.6.2(a), mounted in front of and in obvious look at the brand new driver, that is triggered whenever malfunction laws routine revealed more than get a laws showing an abdominal muscles dysfunction using one or even more towed vehicle(s). The indication light will continue to be activated for as long as an abs breakdown code from 1 or even more towed automobile(s) is obtainable, whenever the ignition (start) switch is in the “on” (“run”) status, whether the engine try powering. The indication light shall even be triggered as the a out of light mode after ignition is actually turned to brand new “on” (“run”) condition. The new signal lamp would be deactivated at the conclusion of the newest glance at away from light function unless a truck Abs malfunction signal are establish.
(a) Plus the criteria out of dos.3.dos, for each and every trailer and you will trailer converter dolly might be armed with a keen outside antilock malfunction signal light that meets the requirements of 2.3.step three (b) using (d).
3.step 1 Ending length – automobiles and you will busses. Whenever prevented six minutes for every single blend of vehicles sort of, pounds, and speed given for the step 3.1.step 1, throughout the series given within the Table I, per vehicle tractor are made on otherwise immediately after March 1, 1997, and each solitary tool automobile are built to the otherwise immediately after March step one, 1998, will visit least immediately following in the only the exact distance specified within the Table II, measured from the part where way of the provider brake handle initiate, with no area of the vehicle leaving new roadway, with controls lockup enabled simply the following:
(b) To own auto made to pull various other car equipped with air brakes, the stress in the fifty-cubic-inches test tank described inside the step three.4.1(a) will, when measured throughout the basic direction of solution brake manage, slip so you can 5 psi for the only 0.75 moments in the example of cars and you can vehicles, step one.ten seconds when it comes to truck converter dollies, and you can step 1.00 moments when it comes to trailers except that truck converter dollies.
cuatro.step 1.step one Immediately following burnishing the newest brake pursuant so you can S6.dos.six, keep up with the braking system construction towards inertia dynamometer. Having an initial braking system temperatures between 125 °F. and you can 200 °F., make a halt away from 50 m.p.h., keeping braking system chamber heavens pressure at a reliable 20 psi. Measure the average torque exerted because of the braking system since the specified heavens tension are hit before the brake finishes and you may separate from the fixed stacked tire radius given of the tire brand to determine the retardation push. After each and every avoid, change the fresh new braking system instrument or disk up until the heat of the braking system drops so you can anywhere between 125 °F. and you can 2 hundred °F.
(a) Except due to the fact offered inside the six(b) and you can 6(c), per vehicles other than a truck converter dolly will has actually an effective vehicle parking brakes one to in standards from S6.step 1 match the needs of:
6.3.4 The fresh new parking brake chamber demands to own six.step 3.1 and you may six.3.2 are determined the following. For autos and you can buses, having a first tank system pressure from a hundred psi and you will, when the built to pull an automible armed with heavens brakes, which have good fifty cubic inch sample reservoir linked to the also provide line coupling, one solitary leakage variety of incapacity, in any almost every other brakes, from a member designed to have compressed-air or brake liquid (similar to the parenthetical words specified inside the six.step three.1), are introduced in the brake system. Brand new parking braking system handle are actuated as well as the pressures throughout the automobile’s parking braking system compartments are measured about three moments upcoming actuation is initiated. For trailers, towards the have line very first pressurized so you can a hundred psi with the also provide line portion of the truck take to rig (Profile step one) and you can, if the made to pull an auto armed with sky brakes, having good fifty cubic inches shot reservoir linked to the buttocks also provide range coupling, people single leaks method of incapacity, in just about any other brake system, away from a part designed to have compressed air or brake fluid (similar to the parenthetical statement given in 6.step three.1), is produced throughout the brake system. The front also provide line coupling was vented on conditions and you can the newest pressures from the car’s parking braking system chambers are counted about three moments then ventilation is initiated.
six.6.4 Having trailers, with very first requirements because the given in 6.6.5, the fresh new parking brake system are going to be ready meeting minimal performance given in a choice of 6.step one otherwise six.dos, with any single leaks-sort of inability, in virtually any almost every other brakes, out-of an associate made to contain compressed-air or brake fluid (similar to the parenthetical statement specified inside 6.step three.1), after the test sequence specified for the six.six.6.
nine Finally examination. Search this service membership brake system with the standing out of variations and you can into the brake indicator monitor relative to step one.8 and you may dos.2.
S6.1.10 During the a test apart from a fixed vehicle parking decide to try, a truck tractor are checked in the its GVWR by coupling they to help you an unbraked flatbed partial-trailer (hereafter, control trailer) as the specified into the S6.step 1.10.dos to help you S6.step one.ten.cuatro.
S6.2.step 3 Heavens at ambient temperature is brought evenly and continuously more the new brake musical instrument or disc within an acceleration from 2,200 feet per minute.
