How to Do the CDL Air Brake Pre-Trip Inspection

[@devonscope6222]

-Minimum / maximum on governor -Low air pressure warning -Spring breaks supply automatically between 20-45psi -Compressor builds air volume in certain amount of time -Leak test

[@smartdrivetest]

Grandma Likes Everyone Because Grandma's Loveable - Governor (Min); Low Air; Emergency Brakes Apply; Buildup Test; Governor (Max); Leak Test. All the very best, Cheers Rick

[@ctmtuber]

Outstanding video! Excellent presentation, complete and concise instructions and information. I was confident about my knowledge test, apprehensive about the pre-trip test, happy to say I passed today. After watching the video I had my mantras; "Secure, not damaged, not leaking " and "5 pressure tests, two tug tests. Governor in/out, low air warning, pressure up time, auto spring brakes, leak test. Spring break tug, service break tug." That was an easy way to make sure I didn't miss any tests and made it easy to remember what's related to each. One thing extra I had to do; I had to manually adjust one of the brakes for pushrod travel, they were all good so had to adjust one pushrod out of tolerance then fix and measure by prybar. Thanks for this video, you can bet I'm going to take in all the rest of your videos. Very valuable, very generous of you to share.

[@safeway3168]

I thought its called "service brake response test" not service brake tug"

[@smartdrivetest]

Hi Chris McNally - Apologies for the late response. You are correct my friend. Parking brake tug test and service brake response test. You're testing that the brakes both apply and release. All the best, Cheers Rick

Great info for someone who has been away from trucking for 12 years. I would highly recommend watching these informative videos before getting behind the wheel. Thank you!

[@zerodegrees8]

Here's the steps for Ontario from a Z course done at a college. Practical test was done on a dump truck. (Remember to narrate to the examiner what and why it is what you are doing) Step 1 Brake Adjustment Test *Chock wheels *Release tractor brakes (push in yellow button) *Ensure air pressure is between 90 & 100psi *Shut engine off *Measure from brake chamber to center of the clevis pin and not distance *Apply service brakes using brake stick *Ensure air pressure is between 90 & 100psi *Take second measurement & note the difference *Tell the examiner the distance of travel *Front brakes are 16 short with an adjustment limit of 1 3/4" adjustment limit (brake type is vehicle specific) *Rear brakes are 30 short with and adjustment limit of 2 inches (brake type is vehicle specific) *If any of the brakes exceed their adjustment limit, the truck will be out of service *Drain the air tanks (wet tank first) looks for moisture, debris and that the valves reseal *If the valves don't reseal, the truck is out of service Step 2 Governor Cut In Test (80 psi) *Start truck *Fan Brakes down to 80 psi and watch for the pressure to rise *If the pressure doesn't rise, the truck is out of service Step 3 Low Air Warning Test (55 psi) *Fan the brakes until warning light and buzzer come on and note the pressure *If the warning light and buzzer don't activate by 55 psi, the truck is out of service Step 4 Compressor check test *With engine revving between 600 and 900 RPM, time how long it takes to build from 85 to 100psi *If it doesn't build in less the 2 minutes, the truck is out of service Step 5 Governor cut out test *Listen for the air dryer to exhaust *If the governor doesn't cut out between 100 and 135 psi, the truck is out of service Step 6 Air Leak Test *Shut off engine *Apply brake pedal and note the brake pressure *Listen for audible air leaks *Time for 1 minute and note air pressure before releasing the brakes *Cannot lose more then 3 psi in 1 minute or the truck is out of service Step 7 Spring Brake Application Test *Apply truck spring brakes (pull yellow button) and hear them apply *If you don't hear the spring brakes apply, the truck is out of service *If unsure the spring brakes are holding, you should do a tug test Tug Test *Remove wheel chocks *Apply power with the spring brakes applied (yellow button out) *If brakes don't hold, the truck is out of service Speech If I found any defect during these 7 steps, I would fill out inspection book and report to owner. If truck is out of service, it is illegal to drive.

[@wealthyintime1]

I forgot to apply the spring brakes after adjusting the brakes. The spring brakes were release when going from governor cut out to drop the pressure quicker than pumping the brakes. Spring brakes were released when doing air leakage test and then doing an brake adjustment by 2 full brake applications. This was an airbrake practical. I did everything right expect applying the spring brakes. A brake check was not done after brake adjustment, although we talked about prior when the instructor was in passenger seat talking to us. Does draining the air tanks apply the springs brakes if they were not applied? The truck in neutral and on flat ground and the key was off position.

[@smartdrivetest]

As I stated, if system pressure in the secondary and primary tank is drained between 20 and 45psi, the emergency spring brakes (parking brakes) will apply. The large powerful spring are held in the released position by air pressure. If you drain the air pressure, the spring cannot be held in the release position, will expand, and apply the parking brakes. If there is anything further we can do, drop us a note. Always happy to help. All the best, Cheers Rick

Hmm, my state CDL manual says to turn the engine off just before you start the test of the low air pressure warning signal. That would seem to make more sense because the air compressor is trying to replenish the air pressure while the engine is running.

[@smartdrivetest]

Hi Steven Litvintchouk - Thank you for your comment. And you are correct my friend. On most air brake inspections, after you do the low air warning test, you shut the engine off to do the emergency brake test.

You did a great job. But remember to tell the people who’s watching the first thing you do is when you get in the cab is to put on your seatbelt!! Because it’s an automatic failure if you don’t have it on when you do your in cab air brake test. Other than that the great job.

[@2010Canuck]

Charles S I'm a retired city bus driver who now occasionally drives rented school buses for church advents in BC. On my city bus doing my pre-trip I was not required to crawl under the bus and check the distance of travel on the push rods. I have also talked to a manager of a school bus system and he indicated because of the auto slack adjusters he does not require his drivers to go under the bus and check rod travel. I have also watched several you tube videos and they don't show anyone going under the bus. Is manually doing a pry bar test a requirement on my routine pre-trip or is it just required when doing a driving test?

[@smartdrivetest]

Hi 2010Canuck - Thank you for your comment and query. For the purposes of your road test, you will be required to go under the bus and check push rod travel.

Hi I’m having an issue I need to know how to demonstrate air leakage test in a MTA bus, I know the PSI no more than 10 psi and no more than 2 psi, to test I need to hold the service break for one min, I’m still confused

[@sugarsdaddy1]

would they expect you to raise the box on a gravel truck in order to inspect the lines from above, or can you simply do that from below?

[@smartdrivetest]

Hi sugarsdaddy1 - Thank you for your query. You can do either my friend - you can do it from below or you can raise the box. My only issue with raising the box is that the examiner may see it as a safety issue and would not want you between the raised box and the frame. All the best, Cheers Rick

[@drivenhome7840]

Why is the Cut in phase void if the pressure drops below 80PSI? You don't explain that.

[@smartdrivetest]

Hi Driven home - Thank you for your query. 80 psi is the absolute minimum according to regulations that the governor must return the compressor to the load phase. Thus, if you let the air pressure go lower, you're not within the parameters of the required test. All the best, Chers Rick

Hi Rick, Great video! As an Air brake instructor here in Ontario we don't do the 50psi to 90psi test for build-up but only test 85psi to 100psi. just wondering what the differences are in other provinces and states. is there a website with that info? Thanks again. -Rob

[@smartdrivetest]

Hi Robert den Broeder - Thank you for your comment. And no, there isn't a website - you have to go through the individual manuals. Some of the other provinces and states are going the 85-100psi in 45s with the engine at flat idle too. I think it's SK--maybe QC too--that's added that the trailer air supply must shut off air to the trailer above 50psi. And then the normal - parking brake applies the emergency brakes between 20 and 45psi. If there is anything further we can do, drop us a note. Always happy to help. All the best, Cheers Rick

[@attackhelicopter2900]

Man! The examiner nailed me on the 4-60 test today! In our truck, we must put our transmission in first gear, turn off the engine, release the spring brakes, and press and hold the service brakes for one minute. While i pressed my brakes and the timer was ticking, I noticed my primary air gauge started rising. I thought it was abnormal since I was expecting it to drop maybe like 1 or 2 pounds. But I just continued and I told my examiner: "Ok my minute is up, primary was at 102, it is now at 105, I gained 3 pounds of pressure, it's a good test". But he said that this was a bad reading because the pressure is not supposed to rise. My instructors at school told me it's not necessarily normal for it to rise instead of drop but it does happen sometimes. Is this true or not?? When I released my spring brakes, I did wait for all the pressure to ease off my valves. I even took a little more time to grab my phone, look for the timer app, look for the stop-watch section, and press start. So how much more longer was I supposed to wait?

How do you inspect the brake diaphragm and determine whether it is ruptured or not?

[@smartdrivetest]

Hi Rob - thank you for your comment and query. Most of the time--in my experience--its a service brake diaphragm that goes. A leak test will identify a ripped service brake diaphragm. For a spring brake diaphragm, it's going to leak when the parking brakes are released and one of your wheels is going to lock up - you'll know pretty quick. For both, let a mechanic deal with the breakdown. If there is anything further we can do, drop us a note. Always happy to help. All the best, Cheers Rick

Im taking my cdl test for class B friday.. I want to know if the MCI J4500 has two air tanks? I know it has disc brakes, no push rods or slack adjusters so what are the major components I need to mention? If you could help I would really appreciate it.

[@smartdrivetest]

Hi Daclassie Sims - thanks for your comment. All air brake vehicles have a secondary and primary air tank. If it is an ADIS (Air Dryer Integrated System), which it probably is, you won't have a wet tank. If the governor is within close proximity to the air dryer, it's an ADIS system. See this video: kzbin.info/www/bejne/r3PMXmmbisibZtk On disc brakes, say, rotor, callipers and pads are all secure, not damaged and not leaking. Tell the examiner the brakes are self-adjusting and must be checked for adjustment by a qualified technician. Check the brake chambers and inside the hub. The bus will have ABS, so check the ABS valve and the electrical line zippy tied to the brake line. If there's anything further we can do, drop us a note. Always happy to help. All the best, Cheers Rick

I have a question.... I have a 1984 Tandem grain truck that I purchased about a year ago, It has airbrakes... It has 2 tanks at the rear that have a drain valve each, and one tank under the cab by the right side fuel tank... The one by the fuel tank has 2 drain valves on it... I never seem to get any air out of the one. I've only ever got a little bit of water and some gunky stuff... Is that just the wet tank? The other valve works fine I get lots of air when I open it... The brakes and everything all seem to work just fine, and when i bought it I had to get an inspection done and nothing was said about it so I'm assuming it's normal.. Am I right to assume that or should I get it checked out? I would thank you kindly if you could answer my question... Thanks...

[@smartdrivetest]

Hi TheFarmerfitz - Thank you for your comment. Usually when an air tank as two drain valves, it is 2 tanks created by a bulkhead. The way to find your wet tank is to pump to full pressure. Take note of the pressure on the gauges and then go out and drain each tank - one at a time. The tank that doesn't drop the needles is your wet tank because it doesn't have a pressure gauge. There is a possibility that the tank by the fuel was replaced and the person who did it didn't realized that it was 2 tanks, rather than one. That's only one possibility. The only other possibility is an emergency tank in the event of break down, but I've never encountered one of those. If you determine which tank is the wet tank, that might alleviate some of the mystery. However, if you have 3 tanks that are functioning, then your system--as you stated--should be working fine. If there is anything further we can do, drop us a note. Always happy to help. All the best for the holidays, Cheers Rick

[@TheFarmerfitz]

Thanks for the reply... The one by the fuel tank as I said has 2 drain valves... is it possible that there is 2 compartments in one tank... On that tank, when I turn the tap on the rear drain valve I get the usual blast of air, and usually some moisture... The other one I have only ever had a little dribble of water but no air at all..... The other two tanks I do the same and I get the usual blast of air with a bit of moisture(depending on how long it's been since draining).... It's probably like you said...

I'm sure this is a great video for Canadian students. However, it is so different for those of us in the US that if you follow this video to the letter you will fail. The pressure ranges are different, and the order in which you do the tests is close to the reverse. If you are from the US, I recommend that you look up a video from someone in the states.

[@smartdrivetest]

What state are you in my friend? Despite an air brake system being almost the same on every truck in the United States, every driving school wants to do the pre-trip inspection differently, and each state has slightly different numbers...not much, but slightly different.
