The newest election for the solution cannot affect the performance conditions given during the S5

(b) In the accessibility to producer, getting automobile equipped with braking system solutions and that need a common diaphragm, the fresh abilities conditions given for the six(a) and this need to be exposed to people unmarried leakage-type of incapacity inside a common diaphragm could possibly get rather become confronted by the level of leakage-type inability determined inside the six.eight. 6(a) and this implement having single leaks-method of problems apart from problems inside the a familiar diaphragm.


(c) In the option of producer, the new truck part of people farming commodity trailer, heavy hauler trailer, or pulpwood truck get be considered regarding § of label as opposed to the requirements out-of six(a).

(a) In the example of a vehicle przeczytaj ten post tutaj except that a truck-tractor that’s armed with more than several axles, in a way that the newest quotient static retardation force/GAWR is not less than 0.28 your shaft except that good steerable top axle; and you can

(b) Regarding a trailer-tractor that is equipped with over a couple of axles, in a way that brand new quotient static retardation force/GVWR isn’t lower than 0.fourteen.

six.2 Amount carrying. With vehicle parking brake system applied, the auto shall continue to be stationary up against uphill and you may against downhill into a smooth, dead portland cement real street that have good 20-per cent amount, both

6.3.step 1 Brand new vehicle parking brake system is capable of attaining the minimal efficiency given in a choice of 6.step one or 6.2 that have one unmarried leaks-form of failure, in any most other brakes, regarding a member built to consist of compressed air otherwise braking system water (leaving out inability from some a brake chamber houses but and additionally failure of every brake chamber diaphragm that’s part of every other brakes also a good diaphragm which is preferred to brand new vehicle parking brake system and just about every other brake system), in the event the challenges on the car’s vehicle parking braking system compartments is at the amount determined in the 6.step 3.4.

Along with almost every other brakes produced inoperative, during a fixed drawbar make an onward or rearward recommendations, the fixed retardation push created by the utilization of new parking brake system is going to be:

six.step 3.2 A physical form will be provided, after a parking braking system application is made with the challenges inside the the new vehicle’s vehicle parking brake spaces in the membership determined during the 6.step 3.4, and all sky and you may fluid demands regarding automobile’s braking systems is then bled down seriously to no, and you can without needing electrical power, holds the latest vehicle parking braking system software with sufficient parking retardation push to meet with the lowest show specified into the 6.step 3.step one as well as in often 6.step one or six.2.

6.3.3 To have cars and vehicles, with a primary reservoir system pressure off 100 psi and, if built to pull a vehicle armed with air brake system, having good 50 cubic inch test reservoir connected to the also provide range coupling, zero later than three seconds from the time out of actuation regarding the latest parking brake manage, brand new technical function described in the 6.step 3.dos should be actuated. Getting trailers, to the supply line initially pressurized so you can one hundred psi making use of the also provide range part of the trailer test rig (Profile 1) and you may, when the built to tow a car or truck equipped with air brakes, with good 50 cubic inch sample tank attached to the butt also have line coupling, zero after than just about three mere seconds ever since venting on atmosphere of your top likewise have range coupling is established, the new technical form regarded for the 6.step three.dos will be actuated. This specifications can be found getting autos, vehicles and trailers both which have and you can with no unmarried leakages-sorts of incapacity, in virtually any other brake system, regarding a part made to contain compressed-air or brake water (consistent with the parenthetical keywords specified in the six.3.1).
