New vehicle parking brake control shall be independent on solution braking system manage

Thirty moments shortly after for example actuation, a launch actuation of one’s parking braking system handle is established

6.cuatro Parking braking system control – vehicles and you may buses. It shall be operable by the a person sitting regarding regular operating position. The manage would be understood such that specifies the fresh variety of manage operation. The latest parking brake handle will manage brand new vehicle parking brake system of your car as well as one heavens braked vehicle that it’s designed to tow.

6.5.step 1 Getting autos and you can buses, which have initially conditions because given in the 6.5.2, at all times after a software actuation of your vehicle parking braking system control, with any further quantity of tension, otherwise blend of amounts of stress, from the reservoirs of any of your automobile’s braking system solutions, zero reduction in parking braking system retardation force shall come from good launch actuation of your vehicle parking brake manage unless new parking brake system have the capability, once such as for instance launch, of being reapplied at a consistent level fulfilling the minimum results given either in 6.step one otherwise 6.2. This specifications will be found each other which have and you will without any system towards the, along with and you will instead unmarried leakages-sorts of incapacity, in almost any other brakes, out of an associate made to include compressed air or brake fluid (similar to the parenthetical terms specified inside the 6.3.1).

6.5.2 The first requirements to own 6.5.step 1 are listed below: New reservoir system stress was one hundred psi. In the event your automobile is designed to tow an auto armed with heavens brakes, an effective fifty cubic inches try tank are attached to the likewise have range coupling.


6.5.3 Having trailers, that have first conditions due to the fact given in the six.5.4, constantly just after actuation of the vehicle parking brakes from the venting the front also provide line coupling into atmosphere, and with people next level of pressure, otherwise mixture of amounts of tension, in the reservoirs of every of your own automobile’s brake assistance, the fresh new vehicle parking brake system will not releasable because of the repressurizing the supply range by using the have range part of the trailer shot rig (Shape step 1) to your pressure above 70 psi, except if the brand new vehicle parking brakes have the capability, immediately after such as for instance discharge, away from reapplication from the further ventilation of side have range coupling towards surroundings, at a level conference minimal performance specified in a choice of six.1 otherwise six.2. That it requirement would be found both which have and you may without the single leakage-particular inability, in just about any almost every other brake system, of an associate built to consist of compressed air otherwise braking system fluid (consistent with the parenthetical words specified in the six.step 3.1).

six.5.4 The first requirements getting six.5.step 3 are as follows: The new tank program and supply range was pressurized to a hundred psi, by using the have range portion of the truck sample rig (Contour step 1). In the event your vehicles was designed to tow an auto equipped with heavens brake system, an effective 50 cubic inches shot reservoir are linked to the buttocks likewise have range coupling.

6.6.1 To possess trucks and you can busses, with very first standards while the specified inside six.six.2, the vehicle parking brake system should be with the capacity of meeting the minimum performance specified either in 6.1 otherwise six.2, with people solitary leaks-method of inability, in any almost every other brake system, out-of a part designed to consist of compressed-air otherwise brake liquid (similar to the parenthetical terms given from inside the 6.step three.1) at the end of the test series given inside six.six.3.

six.six.2 The initial criteria having 6.six.step one are listed below: Brand new system is found on. The new reservoir system tension try a hundred psi. If the automobile is made to pull a car armed with heavens brake system, a good fifty cubic inch decide to try reservoir is connected to the also have line coupling.

6.6.step three The exam series for six.6.1 is really as pursue: The new engine is actually deterred. People solitary leakage method of failure, in almost any other brakes, regarding a member made to have compressed air otherwise braking system water (similar to the parenthetical terminology given inside 6 free haitian dating.step 3.1), will be delivered regarding brake system. A credit card applicatoin actuation of one’s vehicle parking brake control is then generated. Thirty mere seconds following discharge actuation, a last application actuation of parking braking system control is done.
