6.4 Vehicle parking brake control – autos and busses. They would be operable of the one seated from the regular operating standing. The brand new manage are recognized in a fashion that specifies brand new particular control process. This new vehicle parking braking system control shall control brand new parking brakes of the auto and of any air braked car it is customized to help you tow.
six.5.step one To possess automobiles and you may vehicles, having initial criteria just like the specified from inside the six.5.2, at all times after a loan application actuation of your parking braking system control, sufficient reason for one subsequent level of stress, otherwise combination of quantities of tension, regarding reservoirs of any of the vehicle’s braking system solutions, no lack of parking braking system retardation force should result from an excellent launch actuation of your own vehicle parking brake control except if the fresh vehicle parking brake system have the capability, immediately following for example discharge, of being reapplied at a rate conference the minimum efficiency given in a choice of 6.1 or six.dos. This requirement are going to be met one another with and you may without the motor into, along with and you may as opposed to single leaks-variety of incapacity, in virtually any almost every other brake system, off an associate designed to contain compressed-air otherwise brake liquid (similar to the parenthetical words given inside six.step 3.1).
six.5.2 The first conditions for 6.5.step one are listed below: Whether your vehicle is made to pull a car or truck armed with heavens brakes, a fifty cubic inch test tank try linked to the likewise have line coupling.
six.5.step three To possess trailers, with initial conditions because given within the 6.5.4, at all times immediately following actuation of your own vehicle parking brakes of the ventilation the leading have line coupling into surroundings, along with people then number of pressure, or combination of levels of pressure, regarding the reservoirs of every of one’s vehicle’s brake solutions, the fresh vehicle parking brake system should never be releasable of the repressurizing the production line utilizing the likewise have range portion of the truck take to rig (Profile step one) to any tension above 70 psi, except if the vehicle parking brakes have the capability, once particularly release, regarding reapplication from the subsequent venting of one’s front supply line coupling to the conditions, for a price meeting minimal show specified in a choice of 6.step one or six.dos. So it requisite shall be found both which have and you can with no unmarried leakage-sort of inability, in any other brakes, regarding a member designed to incorporate compressed air otherwise braking system liquid (similar to the parenthetical keywords specified from inside the six.step three.1).
6.5.cuatro The original requirements to own six.5.step three are listed below: Brand new reservoir system and gives range are pressurized in order to 100 psi, using the supply line part of the truck shot rig (Shape step 1). If for example the auto was created to tow an automible equipped with air brakes, an effective 50 cubic inch test reservoir was attached to the butt have line coupling.
The fresh tank program stress is a hundred psi
six.6.1 To possess automobiles and vehicles, which have first conditions since specified within the 6.six.dos, this new parking brake system would be effective at conference the minimum efficiency specified in both 6.step one or 6.dos, which have one solitary leakage-types of incapacity, in almost any other brake system, out-of a part designed to incorporate compressed air or braking system liquid (consistent with the parenthetical terminology specified inside six https://datingmentor.org/pl/hinge-recenzja/.step 3.1) after the test sequence specified inside the 6.six.step 3.
6.six.2 The original criteria to possess six.6.step one are as follows: Brand new system is found on. In the event your car was created to pull a car or truck equipped with air brakes, a great fifty cubic inches sample reservoir is actually connected to the also have line coupling.
6.6.step 3 The exam sequence to own six.6.step 1 is as pursue: The newest motor are switched off. People single leakages form of incapacity, in every other brakes, regarding a member designed to incorporate compressed-air otherwise brake liquid (similar to the parenthetical terminology specified inside the 6.3.1), is then put regarding the brake system. A loan application actuation of the vehicle parking brake handle will then be produced. Thirty moments shortly after including actuation, a production actuation of the vehicle parking braking system manage is made. Thirty moments after the release actuation, a last app actuation of your vehicle parking brake manage is done.
