6.4 Vehicle parking braking system handle – automobiles and you may vehicles. They will likely be operable by the one sitting in the regular driving standing. The newest handle would be known in a fashion that specifies the brand new method of handle operation. The vehicle parking brake handle should control the fresh parking brakes of vehicles as well as people sky braked auto that it is customized to help you tow.
six.5.step one To possess autos and buses, which have initially requirements given that specified in 6.5.2, all the time immediately following a loan application actuation of one’s parking brake manage, in accordance with people subsequent number of pressure, otherwise mix of quantities of pressure, regarding reservoirs of every of your own vehicle’s braking system possibilities, no lack of parking braking system retardation force should result from good release actuation of one’s vehicle parking braking system control unless of course the fresh new vehicle parking brakes are capable, after such as launch, of being reapplied at a consistent level meeting the minimum overall performance specified in both 6.step one otherwise 6.dos. Which specifications can be found one another that have and you may without having any engine on the, sufficient reason for and instead of unmarried leakage-type incapacity, in almost any almost every other brake system, out-of a part made to incorporate compressed air or brake fluid (consistent with the parenthetical phrase specified inside 6.step three.1).
six.5.2 The first conditions getting 6.5.step one are as follows: In case the vehicles was created to tow an automobile equipped with heavens brakes, an excellent fifty cubic inch take to reservoir is connected to the also provide range coupling.
6.5.step 3 To have trailers, with initial conditions because the specified in six.5.4, constantly after actuation of one’s vehicle parking brake system of the ventilation the leading have range coupling on the atmosphere, in accordance with one next amount of tension, otherwise mixture of degrees of pressure, regarding the reservoirs of every of automobile’s brake systems, the newest parking brakes shall not releasable because of the repressurizing the production range by using the also have range part of the trailer try rig (Figure step one) to any pressure significantly more than 70 psi, unless of course the latest parking brake system are capable, shortly after for example launch, out of reapplication by the next venting of your own top likewise have range coupling towards ambiance, at a level appointment minimal performance specified in a choice of 6.step one otherwise 6.2. It requirement would be met each other which have and without having any unmarried leakage-sort of inability, in almost any most other brake system, off a member built to consist of compressed air otherwise brake water (consistent with the parenthetical terms specified in the six.step 3.1).
six.5.4 The initial requirements for 6.5.3 are as follows: The newest reservoir program and offer range was pressurized so you can a hundred psi, by using the also provide range portion of the truck test rig (Profile step one). If your auto is made to tow a motor vehicle armed with air brakes, an excellent 50 cubic inch shot tank was connected to the butt supply line coupling.
The new tank system stress is actually 100 psi
six.6.1 Getting vehicles and you may busses, which have 1st conditions while the given in the six.six.2, the fresh vehicle parking brake system is with the capacity of conference minimal overall performance specified in both 6.step 1 or six.dos, having one solitary leakage-type failure, in any escort babylon Hayward CA almost every other brake system, away from a part designed to contain compressed-air or braking system fluid (similar to the parenthetical statement specified into the six.step three.1) after the test sequence specified in six.6.step 3.
six.six.dos The initial conditions to have 6.6.step one are as follows: The system is on. In case your car was designed to pull an automible equipped with air brakes, a great 50 cubic inches try reservoir try connected to the supply range coupling.
6.six.step three The test series to own six.6.step 1 is just as observe: This new system was turned-off. People single leaks form of failure, in just about any almost every other brake system, from a part built to contain compressed-air or brake fluid (consistent with the parenthetical statement specified when you look at the six.step 3.1), is then delivered regarding brakes. A credit card applicatoin actuation of your own vehicle parking braking system handle will be produced. Thirty moments just after including actuation, a production actuation of the parking braking system manage is done. 30 seconds following launch actuation, a last software actuation of your parking brake control is created.
