Air Brake Test Question For Volvo Owners


Tahoe Shark

Recommended Posts

I am taking the driving portion of my non commercial A test in two weeks so I have been practicing the pre trip and air brake tests. I have an 09 Volvo 670 with a D13/Ishift transmission.

When I start the truck the low air buzzer and the red light/ dash light and warning message come on and continue until approximately 60 lbs of pressure builds and the buzzer and warnings disappear. It builds pressure rather quickly and the cut out activates at about 135lbs. Now here is the question. When I turn the truck off and the key back on it holds the same pressure with the brake applied for a minute easily. Now during the air bleeding process of pumping the brake the lights and dash visual warnings come on at about 60 lbs but the buzzer does not sound. I continue bleeding air off and the parking brake pops out at approx 25 lbs. is this normal or should the buzzer come on at 60 lbs as well as the lights? The driver test in Nevada seems he  to indicate all that is needed to pass is the visual warnings. Could some of the Volvo owners out there see if the buzzer comes on on the way down in pressure. If they do I may have to have a repair done to the truck to get the buzzer to activate.

 

Thanks in advance

You need a visual, as well as audible warning signal. How low dose the pressure have to drop before the buzzer kicks in? Or, does the key need to be cycled to initiate the buzzer? Either way, it should come on and off with the warning light.

I have been wrong before, I'll probably be wrong again.

Bleed it all the way down. Will it ever come on, without shutting off the key? Once the pressure is zeroed, cycle the key Off/On. Does the buzzer start instantly, or does the pressure have to sit low for a while (overnight, a week, a month) until you get around to starting the truck again? You should have 2 pressure switches, that run parallel, to control the light and buzzer. 1 switch fed from the wet tank, 1 from the dry tank. Either/or switch will control the indicators.

I have been wrong before, I'll probably be wrong again.

Something sketchy in the system.

What about cycling the key? Instant alert, or does it have to sit a while before the buzzer kicks in?

On my Volvo, the audio alarm only came on with the engine running.  When I took my CDL test I warned the examiner before we started that was how the Volvo works.  The requirement for an audio and visual alarm is only for a running engine.

Bingo,

Thank you very much Mark! I just went outside and tried the same test with the engine running and all the warnings came on including the buzzer when quickly bleeding off the air. I will make sure to tell the examiner about how Volvo does the warnings.👍

I wasn't required to do an air leak down test when I took driving test. Mine was in Livingston, TX

Nevada requires it for a non commercial A with a vehicle equipped with air brakes.

Yes, I understand that we are NOT commercial vehicles but the Fed Regs governing the equipment required in any truck tractor that is equipped with air brakes state you must have a warning device that "gives a continuous warning to a person in the normal driving position when the ignition is in the “on” (“run”) position and the air pressure in the service reservoir system is below 60 psi. The signal shall be either visible within the driver's forward field of view, or both audible and visible".

So, if you only have one it must be visual. We let deaf people drive, we do not let blind people drive.

I would be happy to share what occurred on my driving test. This pertains to a Nevada class A non commercial test.
 

Appointment was @8am and I arrived early. Sat outside the DMV in 16 degree temps for 30 minutes (COVID rules). A nice lady who turned out to be the chief examiner approached me and asked if I was the non commercial applicant. I said yes and she informed me we would start promptly at 8 and there would be two additional examiner trainees joining us. Not good news for me I thought to myself.

At 8 the guard (yes Nevada has DMV guards) came and got me and sent me to a window for commercial and non commercial driving tests. I finished the paperwork, I already passed the written three tests, and was told to meet the examiners out in the test area. I made my way out and all three ladies were standing around my Volvo just looking at it. I chose to take my test with a 14,000 GVW dump trailer and it did look a little funny behind the 670. We introduced ourselves and the chief examiner told me all three would be grading me. Great, three chances to screw up.

We started the pre trip and it was in a different order than I studied but that was the rule for the day. I went through the engine compartment, wheels/tires, tractor coupling, trailer tongue , and lighting on the truck and trailer. We then did the cab check, engine start and air brake tests.

All three then met and graded me and I passed the pretrip portion. Then on to the lane forward, lane backing and the ally dock tests. Those were actually the least of my concerns, I have been pulling large trailers for 45 years. I passed those test without errors.

The last part was the street driving test and two of the three examiners were in the truck. It went well but I did get a couple of “suggestions”. I drove to slow in residential areas, I could slightly slow down on freeway exits and in the business sections I drove 30 instead of 35. Anyway I passed with flying colors and the ladies all thought the truck was awesome. 
 

My license arrived yesterday and now we will work on my wife getting her Class A N/C.

Fortunately for me I took the test in Nevada. I missed your point.

If you are an unlicensed driver you cannot drive to your drivers test unless you have a properly licensed person with you or delivering your test vehicle to the location. 

I think that was the point.

Not the case in rural Nevada. I asked specifically if I needed to have a class A driver come with me and the answer was no for non commercial.
It just seemed odd to me that the response to my story was “you would have failed in my state”. If I was in MD I would have done it differently.
