Air Brakes Test....ugh

The biggest problem people had in my class was forgetting to release there brakes. That should be the first thing you do lol. And always I mean ALWAYS remember to turn your power back on and let your gauges sweep. To me the hardest part was the numbers (4 psi in one minute, low air light should come on between 20 and 45 psi etc. ) luckily I passed on the first try lol. Just remember to release your brakes. Lol good luck! !!!

Using cruise control to build pressure just doesn't sound like a good idea. I'll pass....

RV,

Here is a video on pre-trip inspection. Brake test starts at 49:15. Hope it helps and doesn't add to any confusion about how you are being taught. But I think the guy does a good job on explaining the brake test. He talks about some things Metalhead mentioned. Remember and understand SALE. Watch the video and you'll know what I mean.

During your test, using the cruise to run up the air pressure will probably fail you so why you would practice that way doesn't make sense on such a specific part of the test. You mention it not cutting out at 125 yet the range for the governor to kick is between 100-140. Not every truck will react the same way which is why it's important to fully understand the procedure and each step. Don't get used to the truck you're in because it'll most assuredly bite you in the ass. I knew people who screwed themselves by anticipating when the brake valves would pop out on the final step and they got so used to watching that gauge rather than watch and listen to the valves that they failed because they stopped fanning of the brakes, thinking the valves had popped. Don't over think this, don't try to make cheats for it and don't get too comfortable as you practice it. Learn it verbatim as required by your state and follow each step specifically as stated. Unless of course you want to test more than once.

That's what the sheet my school gave to me and instructors have told us to do. you turn on the cruise control and set it to about 10k rpm

You're in neutral and the brakes are engaged... you're not going anywhere. It's like when you start a car and in parked gear and rev the engine... not gonna go anywhere cause you're not in gear, you're just supply more power to things. I had the same concern at first till I asked and thought logically about it.

It really does seem like Texas is different in every way when it comes to testing standards. things they allow that other states don't, things they make you do vs other states don't and vice versa. Beginning to wonder if they are like that on purpose or it's just a really big coincidence. meh long as I know what I can and can't do to pass.

I hope you mean 1k rpm LOL

yeah I mixed it up with a cars tach... on trucks it's the number x100 in a car it's the number times 1000 because the numbers on tach int rouck are dbl digit, 5, 10, 15, 20, etc and in a car it's single digit range 1,2,3,4,5, etc. just got things mixed up a bit.
