six.5.step one To possess trucks and busses, that have initial standards since the specified in the 6.5.2, all of the time just after a loan application actuation of parking brake control, in accordance with one then level of tension, or blend of amounts of tension, on reservoirs of every of your own automobile’s brake possibilities, no loss in vehicle parking braking system retardation push should originate from a great launch actuation of the vehicle parking brake control unless of course the latest vehicle parking brake system have the capability, immediately following such as for instance discharge, to be reapplied at a level conference the minimum efficiency specified in both six.1 or 6.2. Which requirement shall be met both which have and you may with no system with the, in accordance with and you will instead of single leaks-sorts of incapacity, in any almost every other brake system, away from a member made to consist of compressed air or braking system fluid (similar to the parenthetical phrase specified in the six.step three.1).
six.5.dos The original standards getting 6.5.step one are as follows: In the event your auto was created to tow an automible armed with air brake system, good 50 cubic inches sample tank try attached to the likewise have range coupling.
6.5.3 Getting trailers, with 1st requirements just like the given from inside the 6.5.cuatro, constantly just after actuation of one’s parking brakes by the ventilation the front also provide line coupling into the surroundings, along with one further number of stress, or blend of amounts of pressure, on reservoirs of every of the vehicle’s brake expertise, the newest parking brake system shall not be releasable by repressurizing the production line with the also provide line portion of the truck decide to try rig (Profile step 1) to almost any tension more than 70 psi, unless of course the fresh parking brake system are capable, once such as launch, away from reapplication of the after that ventilation of your own front side also provide line coupling to the environment, at a consistent level conference minimal abilities given in both 6.step 1 or 6.2. So it criteria is fulfilled one another that have and you will without any unmarried leakage-type incapacity, in any almost every other brake system, away from an associate made to have compressed air or brake liquid (similar to the parenthetical words given within the 6.step three.1).
six.5.cuatro The initial requirements having 6.5.3 are as follows: Brand new reservoir system and supply range is actually pressurized to help you one hundred psi, using the also have range portion of the truck try rig (Contour 1). If your car is made to tow a car equipped with heavens brakes, an effective fifty cubic inch attempt reservoir is attached to the butt have line coupling.
This new reservoir system tension is actually a hundred psi

6.six.dos The initial criteria to possess 6.six.step 1 are listed below: This new motor is on. In https://datingmentor.org/escort/hayward/ case your vehicle was designed to tow an automobile equipped with sky brake system, an effective 50 cubic inch sample reservoir try connected to the likewise have range coupling.
6.six.step three The test sequence to possess 6.6.step one is just as uses: The newest engine try turned-off. Any single leakage method of failure, in just about any other brakes, regarding an associate made to consist of compressed air or braking system water (consistent with the parenthetical words specified inside six.step 3.1), is then put on the brake system. A loan application actuation of your own parking brake control will be made. 30 mere seconds after such as for instance actuation, a release actuation of parking braking system handle is established. Thirty mere seconds following release actuation, a last application actuation of vehicle parking brake handle is created.
