Pre-Trip & Brake Check You-Tube Help

At my CDL school, we are learning very specific wording that the inspectors at the DMV are looking for. It's a LOT of memorization. 11 full pages worth for the pretrip. Basically in VA what they are looking for is someone to explain what it is they are doing, why they are doing it, (sometimes) what the item does, and what a possible remedy would be if it's needed. For example, when checking the air compressor, air compressor governor, and power steering reservoir, this is how we have to memorize it and say it to the instructor, while pointing to what it is we are describing.

"I am checking the air compressor. It is not cracked, bent, or broken. It's properly mounted and secured to the vehicle. I hear no leaks. It is gear driven. If it was belt driven I would check the belt tension to see that ther is no more than 1/4 inch of play.

I am checking the air compressor governor, which is located inside the air compressor. It is not cracked, bent, or broken. It's properly mounted and secured to the vehicle. The hoses are not cracked, dry-rotted, or broken. All fittings are tight. I hear no leaks. It will cut in at 100psi and out at 125 psi.

I am power steering reservoir. It is not cracked, bent, or broken. It's properly mounted and secured to the vehicle. I see no leaks. The hoses are not cracked, dry-rotted, or broken. All fittings are tight. I'll check the level daily with this dipstick and fill it to the proper level."

So, yeah. It's absolutely a TON of memorization. But it's so ridiculously thorough compared to many videos I've seen online.

*I am CHECKING THE power steering reservoir.

I don't know how relevant to your situation this would be, but here is an instruction video from Roadmaster school. In the video an instructor goes over the pretrip inspection. At the very end, she goes over air brakes. I hope this helps. https://www.youtube.com/watch?v=125nXCUVUXo
