- In this video we will be testing the Tractor Protection Value, we will be checking and listening for any air leak coming from the service line after we disconnect the blue service line and hold the service brake

Yo. I just subscribed because you are very clear and easy to understand. This manual they gave me shows diagrams that are hard to visualize. Now im confident I understand. U Da Best. imma check out your other vids.
Very simple and understandable explanation of TPValve, marvellous
God bless ya brother!
Thank you nice video
nice explanation 👌
Thank you!
THANK YOU
Amazing
Can you please do whole Air brake?
Please God bless you ❤️
Can you explain how the practical test works, do the Examiner tell you what to do each time or are you supposed to have a paper with you during the test to read out the next step.
Hi,
So the test is divided into 4 parts:
Schedule
coupling
road and then backing!
the examiner tell you what they want to hear and what they want you to do.
👌
It may sound weird, but why did you remove the blue line.
Hi,
We remove the blue service line because it connect to your service pedal. so when you go back inside after removing it you will be holding your brake pedal to listen for any air leak.
How do you know if air leaked out? All you did was turn your head
bro yellow brake will go in
Yellow brake is optional in the tractor protection system. when the service brake is pressed down, You can find out if there is any leak or not!
@@gmtruckforklifttrainingcen810 it can't be optional by any means
we check tractor protection system because when we have to drive tractor without trailer there is no leakage from service line
so when we drive tractor we have to release yellow brale
@@_JasbirBajwa The yellow brake has no play when we are checking the tractor protection system, at most what would happen is when we release the yellow brake the tractor would end up rolling and by pressing the service brake it would only stop or control the tractor.
Fuck truck safety. Just start and go.
That is not at all how you check a tractor protection valve. Both lines should be disconnected while the parking brakes are RELEASED. Not applied. This is supposed to simulate a trailer breakaway. Try to mention that the wheels should be chocked too dude.
Hi,
If you have a trailer attached then we have nothing to do regarding the red supply line as that line supplies air to the trailer. also by releasing the parking brakes it wouldn't matter because the tractor protection can be tested either way!
@@gmtruckforklifttrainingcen810 Look up testing the tractor protection valve inspection bulletin posted by CVSA. If people are paying you to instruct them on this kind of stuff, you should at least be giving them the right information.
@@gmtruckforklifttrainingcen810 You are 100% wrong on your test procedure and you should delete this video as you are passing wrong information. The trailer brakes need to be released, disconnect the service line, pump the brakes, the valve should close before 20 PSI, no air should be coming from service line at this point - this needs to be verified by touch not listening from the cab (thats ridiculous that you think that is effective), remove emergency line and verify air is exhausted and spring brakes are applied - you could also disconnect this line from the get go and let the air bleed out that way. Having the brakes set voids the whole test, the valve in the cab is NOT the TPV, its a separate system called the Trailer Supply Valve (TSV).
@@peterl4823 thank you
U are doing wrong. U supposed to disconnect both airlines. Dont mislead people by doing nuisance tests.
Hi,
Just wanted to clarify you have to disconnect just the blue service line as you are also pressing the service pedal brake, to listen for any air leaks. The red supply line has nothing to do with this question.
thank you
