six.4 Parking braking system handle – cars and busses. It is operable by a man seated in the typical riding standing. Brand new handle should be identified in a way that determine the new style of handle procedure. The newest parking Kliknij tutaj braking system manage shall handle the fresh parking brake system of one’s vehicles and of people air braked car that it is customized so you’re able to tow.
6.5.1 To possess trucks and you can busses, that have 1st criteria as specified within the 6.5.2, constantly once an application actuation of one’s parking brake control, and with people further quantity of pressure, otherwise blend of quantities of stress, on the reservoirs of every of your vehicle’s brake possibilities, zero loss in vehicle parking braking system retardation force will come from good discharge actuation of your vehicle parking brake manage unless brand new vehicle parking brakes are capable, shortly after including release, of being reapplied at a consistent level conference minimal performance specified in both six.step one otherwise six.2. That it criteria can be came across both that have and you can without having any engine to your, along with and you will as opposed to solitary leakage-style of failure, in every almost every other brake system, out-of an associate made to have compressed air otherwise brake water (similar to the parenthetical words specified within the six.step three.1).
6.5.2 The initial criteria to own 6.5.step one are listed below: Brand new reservoir system tension try one hundred psi. If for example the car is designed to tow a vehicle armed with air brakes, a good fifty cubic inch take to reservoir is connected to the supply line coupling.
6.5.3 Having trailers, having very first criteria because given inside 6.5.cuatro, constantly just after actuation of one’s parking brakes of the venting the leading supply line coupling on ambiance, in accordance with any after that level of pressure, otherwise mix of degrees of stress, about reservoirs of every of your own car’s braking system options, the brand new vehicle parking brake system shall never be releasable by the repressurizing the supply range making use of the have range part of the trailer take to rig (Figure step 1) to virtually any stress a lot more than 70 psi, until the fresh parking brake system have the capability, immediately after such discharge, out of reapplication by after that venting of your side have range coupling toward atmosphere, at a consistent level fulfilling the minimum overall performance given in a choice of 6.1 or six.2. Which requirement are going to be met both that have and without any solitary leakage-kind of incapacity, in just about any other brakes, from a member designed to consist of compressed air otherwise brake water (similar to the parenthetical terms given during the 6.3.1).
6.5.cuatro The first criteria for six.5.step 3 are listed below: The brand new reservoir system and provide range was pressurized so you’re able to one hundred psi, using the also have line portion of the truck decide to try rig (Shape 1). Whether your auto was created to pull a car armed with heavens brakes, good fifty cubic inch sample reservoir was attached to the rear also have line coupling.
six.six.step one Having trucks and you can buses, having 1st standards once the specified within the 6.6.2, the brand new vehicle parking brakes might be ready fulfilling minimal show given in both six.step 1 otherwise 6.2, having people single leakages-form of failure, in any other brakes, out-of a member built to consist of compressed air or brake water (consistent with the parenthetical statement given in 6.3.1) at the conclusion of the test succession given in the 6.6.3.
six.6.2 The original requirements to have 6.six.step one are as follows: The fresh engine is on. The fresh new reservoir program stress is actually 100 psi. If your car was created to pull an automible equipped with sky brakes, an effective fifty cubic inches try reservoir was connected to the also provide range coupling.
6.6.step 3 The test succession for six.six.step one can be comes after: The newest system is turned-off. People solitary leaks sorts of failure, in every almost every other brakes, from an associate made to consist of compressed air or brake liquid (consistent with the parenthetical statement specified from inside the 6.step 3.1), will be lead throughout the brake system. An application actuation of the vehicle parking braking system manage will then be generated. Thirty seconds following discharge actuation, a final software actuation of your parking braking system handle is made.
