The newest vehicle parking brake handle are independent on the services brake control

Thirty mere seconds shortly after eg actuation, a release actuation of the parking braking system manage is established

six.cuatro Parking braking system handle – automobiles and you may buses. They are going to be operable of the one sitting regarding normal operating condition. The fresh new manage is going to be identified in a way that determine brand new type handle procedure. The fresh parking braking system manage will handle the vehicle parking brakes of your own car and of one air braked car it is customized in order to pull.

six.5.step 1 Having automobiles and you can vehicles, with initially criteria since specified within the six.5.dos, all of the time just after a software actuation of your parking brake handle, with people next amount of tension, or blend of degrees of stress, in the reservoirs of every of one’s vehicle’s braking system options, zero reduced parking brake retardation push shall result from a great launch actuation of the parking braking system manage unless the fresh vehicle parking brakes are capable, shortly after like discharge, to be reapplied for a price fulfilling the minimum abilities specified in both 6.step one otherwise 6.dos. Which criteria is came across each other with and without the system to your, sufficient reason for and versus solitary leaks-type failure, in almost any most other brake system, of a part designed to have compressed air otherwise brake water (consistent with the parenthetical terminology specified into the 6.step three.1).

6.5.2 The initial conditions for six.5.1 are listed below: The latest reservoir program tension are one hundred psi. If the car was designed to tow a motor vehicle armed with air brake system, good fifty cubic inch test tank is actually connected to the supply line coupling.


six.5.step three To have trailers, which have initial standards since specified for the 6.5.4, all the time shortly after actuation of the parking brakes of the ventilation the front also have range coupling for the atmosphere, along with any next level of pressure, or mix of degrees of pressure, on reservoirs of any of one’s automobile’s braking system possibilities, this new parking brakes shall not be releasable by the repressurizing the supply range utilising the have line portion of the truck shot rig (Contour 1) to virtually any stress over 70 psi, unless brand new vehicle parking brakes have the capability, after like discharge, regarding reapplication by after that venting of the side also provide range coupling towards the conditions, at a level meeting the minimum results given either in six.1 otherwise 6.2. This requirement is came across one another which have and you may without any solitary leakage-sort of inability, in just about any other brakes, out-of a member designed to have compressed-air or braking system water (similar to the parenthetical phrase given within the six.step 3.1).

6.5.4 The original requirements to have six.5.3 are listed below: The tank system and offer range was pressurized so you’re able to 100 psi, utilizing the likewise have range portion of the truck decide to try rig (Profile step 1). If for example the car is designed to tow a car armed with sky brakes, a 50 cubic inches test reservoir was attached to the butt likewise have line coupling.

6.six.step 1 Having automobiles and vehicles, with first criteria due to the fact given in the six.6.2, the fresh new parking brake system is ready appointment the minimum abilities given either in 6.step one or six.2, having people solitary leaks-variety of incapacity, in any other brakes, from an associate designed to contain compressed-air otherwise braking system water (consistent with the parenthetical terms specified for the 6.step three.1) at the conclusion of the exam succession given within the 6.six.step 3.

6.6.dos The first standards to possess 6.6.1 are as follows: The fresh new motor is found on. The brand new reservoir system tension are 100 psi. In case your vehicle was created to tow a vehicle equipped with sky brake system, a 50 cubic inch take to reservoir try connected to the also have range coupling.

six.six.step 3 The test sequence having six.6.step 1 is just as follows: The latest motor are switched off. Any solitary leakage sorts of incapacity, in virtually any almost every other brakes, of an associate built to include compressed air otherwise brake liquid (similar to the parenthetical words given during the 6.step 3.1), will be produced throughout the brakes. A credit card applicatoin actuation of one’s vehicle parking brake control is then generated. Thirty seconds following the launch actuation, a last app actuation of your parking braking system handle is established.
