6.cuatro Vehicle parking braking system handle – autos and you can busses. It are going to be operable by a guy resting regarding normal operating updates. New manage will likely be known such that determine brand new style of handle process. The fresh new vehicle parking braking system handle will handle the parking brakes of your car as well as any air braked vehicles that it is designed so you can tow.
6.5.step 1 To have cars and buses, that have 1st requirements because given into the 6.5.dos, at all times once a software actuation of your vehicle parking brake control, along with one next number of stress, or combination of levels of tension, throughout the reservoirs of any of your own vehicle’s braking system expertise, no reduction in parking braking system retardation force will originate from a good launch actuation of the parking braking system handle unless the newest parking brake system are capable, once including launch, of being reapplied at a level meeting the minimum overall performance specified either in six.step one or six.dos. That it needs should be found each other with and you can without any engine into the, with and you may instead solitary leakages-kind of incapacity, in every almost every other brake system, from a part designed to incorporate compressed-air otherwise braking system fluid (consistent with the parenthetical terms specified during the 6.step 3.1).
six.5.2 The original criteria to own six.5.step one are as follows: The tank system stress are 100 psi. If your car was designed to pull a vehicle equipped with sky brakes, a beneficial 50 cubic inches sample tank was linked to the have line coupling.
six.5.step 3 For trailers, which have first conditions as given within the 6.5.cuatro, at all times shortly after actuation of parking brakes from the venting the leading have line coupling for the environment, in accordance with one further level of tension, or blend of degrees of stress, in the reservoirs of every of the vehicle’s brake options, the new parking brakes shall not be releasable because of the repressurizing the supply line with the supply range part of the trailer sample rig (Profile step 1) to your pressure a lot more than 70 psi, unless the new parking brakes are capable, shortly after for example launch, off reapplication of the next venting of your own top also have line coupling for the environment, for a price fulfilling the minimum results given in a choice of six.step one otherwise six.dos. step 3.1).
That it requirement is found each other that have and you can without any solitary leakage-type incapacity, in every almost every other brake system, from an associate designed to consist of compressed-air or brake fluid (consistent with the parenthetical keywords specified into the 6
6.5.4 The original criteria to possess six.5.step three are listed below: The newest tank program and gives line is pressurized so you can a hundred psi, using the also have range part of the trailer sample rig (Profile step one). In the event the automobile was created to pull an auto equipped with sky brake system, a great fifty cubic inches sample tank is attached to the bottom also provide range coupling.
six.six.step 1 For trucks and you can buses, having 1st standards due to the fact given for the six.6.2, the latest vehicle parking brakes are going to be capable of appointment minimal efficiency specified in a choice of 6.step one or six.2, which have any unmarried leakage-types of inability, in almost any almost every other brakes, regarding a part designed to incorporate compressed-air or braking system water (consistent with the parenthetical keywords given into the 6.3.1) after the test succession given when you look at the 6.six.step three.
six.6.dos The original requirements getting 6.six.step one are as follows: The system is found on. The fresh new reservoir system tension is 100 psi. In the event your vehicle is made to tow a car or truck armed with air brake system, a great 50 cubic inch test tank are attached to the also have range coupling.
6.six.3 The exam sequence to possess 6.six.1 can be as follows: The brand new system are deterred. People solitary leaks method of inability, in any other brakes, off a part built to contain compressed air otherwise brake liquid (consistent with the parenthetical terms specified inside the six.step 3.1), will then be put on the brakes. A software actuation of vehicle parking braking system handle is then generated. 30 moments after like actuation, a launch actuation of vehicle parking braking system control is made. Thirty mere seconds after the launch actuation, a final software actuation of one’s vehicle parking braking system control is done.
