The latest vehicle parking braking system handle is separate from the provider braking system handle

6.cuatro Parking brake handle – cars and you can busses. They are going to be operable by a man seated regarding the regular operating reputation. The latest handle should be understood in a fashion that determine this new particular manage procedure. The latest vehicle parking braking system control should manage the fresh new vehicle parking brakes of your own car as well as one heavens braked automobile that it is tailored to help you pull.

6.5.step 1 To own trucks and vehicles, having very first conditions just like the specified into the six.5.2, constantly just after a loan application actuation of one’s vehicle parking braking system handle, and with people subsequent amount of stress, or blend of amounts of tension, in the reservoirs of every of one’s vehicle’s brake systems, zero reduced vehicle parking braking system retardation force will originate from an effective launch actuation of vehicle parking braking system control unless of course brand new parking brakes have the capability, once such as release, of being reapplied at a level conference minimal show specified in our website a choice of six.step one otherwise 6.dos. It demands would be satisfied both with and you may without the engine with the, with and rather than unmarried leaks-form of inability, in almost any almost every other brake system, out of a member made to incorporate compressed air or brake liquid (similar to the parenthetical words specified inside 6.step three.1).

6.5.2 The original requirements to possess six.5.1 are as follows: If the automobile is designed to tow a motor vehicle equipped with sky brake system, a fifty cubic inches test reservoir is actually linked to the have line coupling.

six.5.step three To possess trailers, with first requirements once the given for the 6.5.cuatro, all of the time shortly after actuation of vehicle parking brake system by venting leading also have range coupling into environment, and with one then quantity of stress, otherwise mix of quantities of pressure, regarding the reservoirs of any of your own vehicle’s braking system expertise, the new parking brakes should not be releasable because of the repressurizing the production line utilising the likewise have line part of the truck attempt rig (Contour step one) to the tension significantly more than 70 psi, unless the fresh new vehicle parking brake system are capable, shortly after including discharge, regarding reapplication by then venting of one’s front supply range coupling with the surroundings, at a consistent level appointment the minimum overall performance given in both 6.step one or six.2. Which requirement are going to be satisfied one another which have and you will with no solitary leakage-method of inability, in just about any almost every other brake system, regarding a member designed to include compressed air otherwise brake fluid (similar to the parenthetical phrase specified in 6.step three.1).

six.5.cuatro The first requirements having six.5.3 are listed below: The new tank program and supply range try pressurized so you’re able to a hundred psi, utilising the supply line portion of the trailer test rig (Shape 1). If your vehicles was created to tow a car equipped with sky brake system, a great 50 cubic inches test tank are linked to the buttocks supply line coupling.

The brand new reservoir program stress is 100 psi

6.6.1 To own vehicles and you may busses, with first criteria while the given inside the six.six.dos, this new vehicle parking brake system would be capable of appointment minimal performance given either in six.step 1 or six.2, with people solitary leakages-type of inability, in every almost every other brake system, away from a part made to include compressed-air or braking system liquid (consistent with the parenthetical terminology given in the six.step 3.1) after the exam succession given in six.six.step 3.

6.6.dos The initial criteria to possess six.6.1 are as follows: The brand new system is on. If your car is designed to pull a car or truck armed with sky brake system, a great fifty cubic inches try tank is actually linked to the supply range coupling.

six.six.3 The test sequence for 6.6.1 can be as pursue: Brand new system try turned-off. People unmarried leakage particular inability, in virtually any almost every other brake system, off a part designed to contain compressed-air or brake liquid (similar to the parenthetical phrase specified during the 6.step 3.1), will be delivered about brake system. A software actuation of vehicle parking braking system control is then produced. Thirty moments after instance actuation, a production actuation of vehicle parking braking system manage is created. 30 moments following the discharge actuation, a final software actuation of the vehicle parking brake handle is created.
