The vehicle parking brake handle can be independent on services brake handle

6.cuatro Parking braking system manage – vehicles and you may buses. It are going to be operable by one seated from the regular riding condition. The newest manage are identified such that specifies this new style of manage process. The fresh new vehicle parking brake handle will handle the parking brakes of your vehicles as well as any sky braked automobile that it’s customized to pull.

six.5.1 To possess automobiles and you may busses, that have 1st requirements while the specified for the 6, constantly immediately after a software actuation of your vehicle parking brake handle, sufficient reason for people subsequent amount of stress, otherwise combination of amounts of pressure, from the reservoirs of any of one’s vehicle’s braking system solutions, no loss of vehicle parking brake retardation force will originate from a great release actuation of the parking brake manage unless of course the new parking brakes have the capability, after eg launch, of being reapplied for a price meeting minimal overall performance given in both six.1 or six.dos. So it requirements can be satisfied each other that have and you will without any motor to your, along with and you can instead unmarried leakage-sorts of incapacity, in virtually any other brakes, off a member designed to include compressed air otherwise braking system water (similar to the parenthetical statement specified inside 6.3.1).

six.5.2 The initial conditions to have six.5.step one are listed below: The newest tank program pressure is actually a hundred psi. When your vehicles is designed to pull a car or truck armed with air brakes, a good 50 cubic inch sample reservoir are attached to the also provide range coupling.

6.5.3 To possess trailers, that have initial criteria once the given in six.5.4, at all times immediately after actuation of your parking brake system by the venting leading also have range coupling with the conditions, and with one further quantity of pressure, otherwise combination of quantities of tension, about reservoirs of every of one’s car’s braking system expertise, the vehicle parking brakes should not be releasable by repressurizing the production range making use of the have range part of the trailer sample rig (Contour step 1) to virtually any pressure above 70 psi, unless brand new vehicle parking brakes are capable, immediately after such as launch, regarding reapplication of the then ventilation of one’s top also provide line coupling towards the atmosphere, at a level conference the minimum efficiency specified either in 6.step 1 otherwise 6.dos. step three.1).

Which specifications are going to be satisfied one another having and you can with no solitary leakage-sorts of inability, in just about any most other brake system, from a part made to contain compressed-air or braking system liquid (similar to the parenthetical statement specified within the six

six.5.cuatro The original requirements to own six.5.step three are as follows: The newest reservoir program and provide line is actually pressurized in order to one hundred psi, using the likewise have range portion of the truck decide to try rig (Profile step one). In the event the automobile is made to pull a motor vehicle equipped with sky brakes, an excellent fifty cubic inch try tank is attached to the buttocks have range coupling.

6.6.1 Having vehicles and buses, that have initial conditions given that given from inside the six.six.2, the vehicle parking brakes would be effective at appointment the minimum results specified either in six.step one or six.dos, which have any single leakages-kind of incapacity, in just about any most other brakes, away from an associate designed to incorporate compressed air or brake fluid (consistent with the parenthetical words specified for the six.3.1) at the end of the test succession specified from inside the 6.6.3.


six.six.2 The initial requirements having 6.six.1 are as follows: New system is found on. Brand new reservoir program tension are a hundred psi. Should your car is designed to pull an auto armed with air brake system, a great 50 cubic inch take to reservoir is attached to the have line coupling.

six.6.3 The exam succession to own 6.6.1 is as observe: The brand new engine is actually turned off. One unmarried leakages types of failure, in any most other brake system, off a part built to consist of compressed air or braking system water (similar to the parenthetical statement specified inside 6.step three.1), is then brought on brake system. A credit card applicatoin actuation of your own parking braking system handle is then produced. 30 mere seconds once including actuation, a release actuation of your parking brake manage is made. Thirty seconds pursuing the launch actuation, a last app actuation of one’s parking braking system handle is generated.
