The fresh new parking braking system control will likely be independent about solution brake manage

6.cuatro Parking brake manage – vehicles and you will buses. They will likely be operable of the a guy seated from the regular riding updates. The newest control shall be identified such that specifies the fresh sort of control operation. The brand new parking brake control will manage the new parking brake system of one’s automobile as well as one sky braked car it is customized in order to tow.

six.5.step one To have trucks and you may vehicles, which have initially requirements while the specified from inside the six.5.2, all of the time immediately after a loan application actuation of one’s vehicle parking brake manage, sufficient reason for one then quantity of tension, otherwise combination of levels of stress, about reservoirs of every of your own vehicle’s braking system expertise, no loss in vehicle parking braking system retardation force shall originate from an effective launch actuation of the vehicle parking braking system handle until the newest vehicle parking brakes are capable, shortly after such release, to be reapplied at a consistent level conference the minimum show given either in 6.step one or 6.dos. So it needs are going to be satisfied both that have and you can without having any motor into, sufficient reason for and you can versus unmarried leaks-type of failure, in every most other brake system, of an associate made to have compressed air otherwise brake liquid (similar to the parenthetical phrase specified inside six.3.1).

six.5.2 The first conditions for 6.5.step one are as follows: This new tank system tension try one hundred psi. In the event the vehicles was designed to pull a car or truck equipped with heavens brake system, an effective fifty cubic inch attempt tank was connected to the supply line coupling.

6.5.step three Having trailers, that have initial requirements since specified when you look at the 6.5.cuatro, at all times once actuation of your parking brakes by the ventilation leading have range coupling towards atmosphere, with any further number of pressure, otherwise combination of degrees of pressure, on reservoirs of every of your vehicle’s braking system options, the new vehicle parking brakes will never be releasable from the repressurizing the supply range with the supply range portion of the truck test rig (Figure step 1) to your stress a lot more than 70 psi, unless the fresh new vehicle parking brake system have the capability, just after for example discharge, away from reapplication because of the further ventilation of your own top supply range coupling for the environment, escort services in Gresham at a consistent level appointment minimal performance given in a choice of six.step 1 otherwise 6.dos. step 3.1).

So it requirement can be met each other with and you will without having any solitary leakage-form of failure, in any almost every other brake system, from a part built to incorporate compressed-air otherwise brake water (similar to the parenthetical words given inside six

six.5.4 The initial requirements to have 6.5.step 3 are listed below: The new reservoir program and provide line is pressurized to a hundred psi, utilizing the supply line portion of the trailer sample rig (Shape step 1). In the event your vehicle was created to pull a motor vehicle armed with heavens brakes, a beneficial fifty cubic inch take to reservoir are attached to the butt have range coupling.

6.6.step 1 Getting automobiles and you may buses, that have 1st criteria because specified in six.six.dos, brand new vehicle parking brakes might be capable of fulfilling minimal overall performance given either in six.step one or six.dos, which have any single leaks-types of inability, in just about any almost every other brakes, off an associate built to have compressed-air otherwise brake water (consistent with the parenthetical words given from inside the 6.step three.1) after the test sequence given inside 6.six.3.

six.6.2 The first standards to possess 6.6.step 1 are as follows: This new motor is found on. This new reservoir system stress are a hundred psi. If for example the car is designed to tow a motor vehicle equipped with sky brake system, a great fifty cubic inch attempt tank is actually linked to the have line coupling.

six.six.step 3 The exam series to have 6.6.step 1 is as employs: Brand new engine is turned off. Any unmarried leakages types of failure, in almost any most other brake system, of a part designed to consist of compressed-air or braking system liquid (similar to the parenthetical terminology given for the six.step three.1), will then be brought on the brakes. A software actuation of one’s vehicle parking brake control is then made. Thirty mere seconds after including actuation, a launch actuation of one’s parking braking system handle is generated. 30 moments following the release actuation, a last app actuation of parking brake manage is done.
