The new vehicle parking braking system control will be independent from the solution braking system control

6.4 Parking brake control – cars and you can busses. They will likely be operable by a person resting regarding the regular operating reputation. Brand new handle shall be known such that determine the fresh new type handle process. The vehicle parking braking system manage shall handle the brand new parking brake system of your vehicle as well as any air braked vehicle that it’s designed to help you tow.

six.5.step 1 To have cars and you may buses, having initial standards since the specified when you look at the 6.5.2, all of the time immediately after a software actuation of your own vehicle parking braking system handle, along with one further quantity of tension, or mixture of degrees of stress, regarding the reservoirs of any of your automobile’s brake possibilities, zero losing parking braking system retardation force will originate from a good discharge actuation of your parking brake manage except if the vehicle parking brake system have the capability, shortly after such as release, of being reapplied at a rate appointment the minimum results given in a choice of six.step 1 otherwise 6.2. Which demands will be satisfied both with and you will without any engine on the, in accordance with and instead of single leaks-sorts of failure, in almost any most other brakes, out of an associate made to have compressed-air otherwise braking system fluid (similar to the parenthetical statement specified in the six.step three.1).

6.5.dos The first requirements getting 6.5.step one are listed below: If the vehicles is made to pull an automible armed with air brakes, a great 50 cubic inches test tank is actually linked to the likewise have range coupling.

six.5.3 Getting trailers, which have initially conditions given that given in six.5.cuatro, at all times immediately after actuation of one’s vehicle parking brake system by the venting the leading also provide range coupling to the ambiance, along with any further level of stress, otherwise mix of amounts of tension, in the reservoirs of any of your vehicle’s braking system possibilities, the fresh parking brakes should not be releasable from the repressurizing the production line utilising the have range part of the trailer take to rig (Shape step one) to almost any pressure above 70 psi, unless of course the new vehicle parking brake system are capable, just after instance discharge, out-of reapplication by after that venting of the front side likewise have range coupling with the surroundings, at a rate fulfilling minimal show given in a choice of six.step one otherwise six.dos. This requisite can be fulfilled both which have and you will with no unmarried leakage-method of failure, in just about any almost every other brake system, off a member made to incorporate compressed-air otherwise braking system fluid (similar to the parenthetical keywords specified when you look at the 6.step 3.1).

six.5.4 The first standards to have 6.5.step 3 are listed below: The brand new reservoir program and provide line try pressurized so you can a hundred psi, utilizing the also provide range portion get it on Review of the trailer decide to try rig (Profile step 1). In case the vehicle is made to tow a vehicle equipped with sky brake system, a good fifty cubic inch decide to try reservoir was attached to the butt have range coupling.

The new reservoir program stress was 100 psi

6.six.step 1 Having cars and you can vehicles, which have initial conditions just like the given from inside the six.six.dos, the parking brakes are capable of conference minimal abilities given in a choice of six.step one otherwise 6.2, which have any single leakages-types of failure, in every other brake system, of a member designed to contain compressed air otherwise braking system water (consistent with the parenthetical keywords specified during the 6.step 3.1) at the end of the test series specified in the 6.six.step 3.

six.6.dos The initial criteria having 6.6.1 are as follows: The fresh new motor is on. If your car was created to pull a car or truck equipped with air brake system, a good 50 cubic inch test reservoir was linked to the have line coupling.

6.6.step three The test sequence getting six.six.1 is as uses: The new system was turned off. Any single leaks kind of inability, in just about any most other brakes, regarding an associate made to include compressed air or braking system water (consistent with the parenthetical terms given within the 6.step 3.1), will then be delivered on the brake system. An application actuation of vehicle parking braking system control is then generated. 30 mere seconds immediately after such as for instance actuation, a launch actuation of one’s parking brake manage is done. Thirty seconds after the launch actuation, a last app actuation of one’s parking braking system control is established.
