six.5.1 To possess vehicles and you may buses, with 1st standards just like the specified inside the six.5.2, constantly immediately after a credit card applicatoin actuation of your vehicle parking braking system control, in accordance with people after that quantity of stress, otherwise mix of quantities of pressure, regarding the reservoirs of any of your own car’s brake expertise, no reduction in parking brake retardation push should originate from a great discharge actuation of vehicle parking brake manage unless the newest vehicle parking brakes have the capability, just after such as launch, to be reapplied for a price conference the minimum results specified in a choice of 6.step 1 otherwise 6.2. This requirement are came across one another having and you may with no system towards the, in accordance with and you may in place of solitary leakage-sort of failure, in virtually any most other brake system, out of a part made to incorporate compressed air otherwise braking system fluid (similar to the parenthetical keywords given during the six.step three.1).
6.5.2 The initial requirements to own six.5.1 are listed below: In case your automobile is made to pull a car or truck equipped with air brakes, a good fifty cubic inch sample tank is actually attached to the also provide range coupling.
six.5.3 To have trailers, with first requirements due to the fact specified gypsy dating app when you look at the six.5.4, at all times after actuation of the parking brake system because of the venting leading supply line coupling on ambiance, sufficient reason for one then level of tension, otherwise blend of levels of tension, from the reservoirs of every of your own automobile’s braking system solutions, the brand new parking brake system should never be releasable by the repressurizing the production range utilising the have range part of the trailer decide to try rig (Figure step 1) to virtually any pressure above 70 psi, unless the latest parking brake system are capable, after such as discharge, regarding reapplication because of the then ventilation of your own front also provide line coupling into the atmosphere, at a level fulfilling the minimum results specified in both six.step 1 or six.dos. So it requirements might be came across each other which have and you will without the unmarried leakage-sort of failure, in virtually any other brakes, away from an associate built to contain compressed air or braking system liquid (consistent with the parenthetical keywords specified inside six.step 3.1).
six.5.cuatro The original standards to own 6.5.step 3 are as follows: The brand new reservoir program and gives range try pressurized so you’re able to a hundred psi, utilising the also have range part of the trailer try rig (Figure step 1).
