(b) Within accessibility to the producer, to have vehicles equipped with braking system options hence use a common diaphragm, brand new abilities standards given in six(a) hence should be confronted by one solitary leakages-variety of failure inside the a common diaphragm get instead become confronted by the degree of leakage-types of inability computed for the 6(a) which pertain having solitary leaks-type problems other than downfalls inside a common diaphragm.

(c) In the accessibility to producer, the new truck portion of any farming item truck, heavy hauler trailer, or pulpwood trailer get be considered away from § for the term as opposed to the criteria of six(a).


six.1 Static retardation force. With all of other brakes made inoperative, during the a static drawbar generate a forward or rearward guidance, the latest fixed retardation force created by the aid of the new vehicle parking brakes might be:

(a) In the example of a vehicle apart from a truck-tractor which is equipped with more than a few axles, in a fashion that new quotient fixed retardation force/GAWR isn’t below 0.twenty-eight when it comes to axle other than an excellent steerable front shaft; and you may

That it demands is found for cars, vehicles and you can trailers one another that have and you can without the single leakages-type incapacity, in almost any most other brake system, out of a part made to have compressed-air or brake liquid (consistent with the parenthetical keywords given inside the 6

(b) When it comes to a trailer-tractor that’s equipped with more two axles, in a fashion that the newest quotient fixed retardation force/GVWR isn’t less than 0.fourteen.

six.dos Degrees holding. With all vehicle parking brakes applied, the automobile should will still be fixed against constant and you will against downhill to your a softer, dry portland cement real road with an excellent 20-% degrees, one another

6.step three.step one The new vehicle parking brake system are going to be effective at reaching the lowest abilities specified either in six.1 or six.dos having any unmarried leaks-type inability, in virtually any other brakes, regarding an associate built to incorporate compressed-air otherwise brake liquid (excluding failure off a component of a brake chamber housing but also failure of every brake chamber diaphragm which is part of any other brake system also an excellent diaphragm that is well-known to the new parking brakes and any other brakes), in the event that challenges in the vehicle’s vehicle parking braking system chambers has reached the degree computed within the six.step 3.4.

six.3.dos A technical setting are provided, immediately following a vehicle parking braking system application is fashioned with the fresh pressures inside the brand new car’s parking brake chambers in the accounts determined for the 6.3.4, and all sky and you will fluid pressures from the automobile’s stopping possibilities are then bled as a result of zero, and you may without the need for energy, holds this new vehicle parking brake application with sufficient vehicle parking retardation push so you’re able to meet the minimal overall performance specified within the six.step three.1 plus in both six.step one or six.2.

six.step 3.3 For automobiles and you will vehicles, having a first reservoir system pressure of one hundred psi and you will, if made to pull an auto equipped with air brakes, having an excellent fifty cubic inches try tank connected to the also provide range coupling, zero after than three seconds from the time off actuation out of the latest vehicle parking braking system manage, this new mechanized form referred to inside six.3.dos can be actuated. Getting trailers, for the supply line initial pressurized to one hundred psi making use of the also provide line part of the trailer take to rig (Profile 1) and you may, in the event the designed to tow an automible equipped with air brake system, that have an excellent fifty cubic inch attempt tank attached to the butt also provide range coupling, zero later than about three mere seconds since that time venting to your ambiance of your side supply range coupling is established, this new mechanized setting referred to for the six.step three.2 should be actuated. step 3.1).
