The brand new vehicle parking brake handle will be separate regarding service brake handle

six.4 Parking brake control – automobiles and you can buses. They might be operable because of the men seated regarding normal driving standing. The latest handle can be recognized such that specifies the type of handle process. The vehicle parking braking system manage should control the parking brake system of automobile and of one sky braked auto that it’s designed so you can pull.

6.5.step one Having autos and you can vehicles, which have initially standards as specified inside the 6.5.2, at all times immediately after an application actuation of your parking braking system manage, in accordance with one subsequent number of pressure, or combination of amounts of tension, on reservoirs of every of your own vehicle’s braking system solutions, zero lack of vehicle parking brake retardation force should come from an effective release actuation of the vehicle parking braking system control unless of course the brand new parking brakes are capable, just after for example discharge, of being reapplied at a rate meeting minimal results given in both 6.1 or 6.2. Which needs should be came across each other that have and you will without the engine to the, in accordance with and you will instead of single leaks-method of failure, in every most other brakes, off an associate made to contain compressed air or braking system liquid (similar to the parenthetical keywords specified within the 6.3.1).

six.5.2 The original standards getting 6.5.step 1 are listed below: The newest reservoir system pressure are one hundred psi. In case your automobile was created to tow an automobile armed with sky brakes, good 50 cubic inch try reservoir is actually connected to the likewise have range coupling.

six.5.step 3 For trailers, with 1st conditions given that given when you look at the 6.5.cuatro, all the time immediately after actuation of parking brakes from the ventilation leading also have line coupling towards the conditions, along with people subsequent level of tension, otherwise mix of quantities of stress, on reservoirs of every of one’s automobile’s braking system expertise, the vehicle parking brake system will not be releasable by the repressurizing the supply range by using the also have range part of the truck attempt rig (Shape step one) to virtually any pressure over 70 psi, unless new parking brakes are capable, immediately following eg release, of reapplication by then venting of your own front side have line coupling for the atmosphere, at a level appointment minimal results specified in a choice of 6.step one otherwise 6.2. step three.1).

That it specifications are going to be satisfied each other that have and you may with no unmarried leakage-style of inability, in virtually any almost every other brake system, out-of an associate made to consist of compressed air or braking system fluid (similar to the parenthetical words given when you look at the six

6.5.cuatro The original criteria having six.5.step 3 are listed below: The brand new tank system and supply range is actually pressurized in order to a hundred psi, using the likewise have range part of the trailer decide to try rig (Figure step 1). If your auto is made to tow a motor vehicle equipped with heavens brake system, a good fifty cubic inch try reservoir try attached to the bottom have line coupling.

six.six.step 1 To have vehicles and buses, with initial standards once the specified in six.six.dos, brand new parking brakes are going to be with the capacity of conference minimal efficiency given in both 6.step one or six.2, which have people solitary leakages-type of incapacity, in virtually any almost every other brakes, from a part designed to include compressed-air otherwise braking system water (similar to the parenthetical statement given within the six.step 3.1) after the test series given during the six.six.step three.

S5

6.six.2 The initial requirements having six.6.step 1 are listed below: The fresh new system is on. Brand new reservoir program stress was a hundred psi. In case your car is designed to tow a car or truck armed with air brakes, a fifty cubic inches sample reservoir try attached to the likewise have line coupling.

six.6.step three The exam succession for six.six.1 is as employs: The fresh new engine is deterred. Any single leakage types of inability, in virtually any most other brakes, of an associate designed to contain compressed air or brake fluid (similar to the parenthetical terms specified when you look at the six.step 3.1), will then be brought throughout the brakes. A credit card applicatoin actuation of your parking braking system handle will be made. 30 mere seconds immediately following such as for example actuation, a release actuation of one’s parking braking system manage is created. 30 seconds following the discharge actuation, a last app actuation of your own parking braking system manage is created.
