Hello, I have been dealing with air brakes since 1997. As I find your explanation is not bad, you should use the proper terminology for the components. If some one is using this video for research to obtain a CDL, or an AZ up north, they will be confused as to what the parts are called. You didn't mention slack adjustor, you just said arm. Or push rod, you just said its a linkage. You also mentioned something about a " bladder"? Did you mean to say diaphragm? I thought the explanation of how the spring brakes work was pretty good, down to laments terms. I am a Canadian Armed Forces Air Brake Instructor and the way we explain to our troops is we send a compressed air signal from either our foot valve or hand valve (for the trailer), to the brake chamber ( after the spring brakes are released, or it could compound the brakes). This action turns a compressed air forcing against a rubber diaphragm in the brake chamber into a mechanical force pushing the push rod out, which is connected to a slack adjustor. This pushing motion turns the force into a force multitier twisting motion because it turns a shaft that has a S cam on the end of it. This twisting S cam pushes the brake liner or pads out to contact the drum. By no means is this a negative criticism, but this is a bit of a pet peeve of mine when it is not explained properly. Sorry

Now granted it’s not the old school one on the column but one a little different style that’s on the dash next to the column. They stopped the column style because of the automatic shifter/ Jake brake setup in KW’s I think. But I have a 18 speed manual, and it’s on the right next to the column for sure.

Great explanation. If I may add, in the incident you had with your trainer where you suffered total air loss, you likely would've still had about 5-7 brake applications before parking brakes locked the wheels. The reason for this is the inversion valve, if you lost total primary pressure but still had your secondary circuit intact, then your secondary air will actuate your rear brakes until it runs out of air - usually a few applications, but enough to stop safely.

The hand brake for the Service Brakes MUST BE MANDATORY! NEVER, EVER TAKE IT ON FAITH THAT THE SERVICE BRAKES ON A SEMI/FULL TRAILER ARE IN PROPER WORKING ORDER! ESPECIALLY ANY CONTAINER CHASSIS! Before you get on a public road surface, use the hand brake valve to check that the service brakes on whatever you’re hooked up to SEPARATELY TEST from the Power Unit (NOT THE FOOT BRAKE). If you experience a blowout on your steering axle, accelerate (providing your power unit hasn’t stupidly been made into a crawler with a Speed Limiting Device) to make sure that your vehicle is stable and ease into your hand brake so that you reduce the chance of a jackknife. It can aide in bringing A trailer back in line behind your cab, just make sure that the road surface isn’t too slippery. Never get ham fisted with a trailer hand brake. If you have multiple units in tow, down shift and use your retarder to slow down before using your hand brake. If you get into a cab that doesn’t have a hand brake, it is an UNSAFE VEHICLE! Don’t even start the damn thing up. And NO, it’s NOT A TROLLEY BRAKE. You’re driving a Big Rig, NOT operating a Trolley Car. When you have time, check to see if your wet tanks are dry on your Power Unit and anything you’re pulling. Keep the dirty side down.

@andrewkuntz37192 жыл бұрын
Faster, safer because of the ability to have a secondary system, and I don’t think with hydraulic brake systems you are able to isolate one wheel end like on air brake systems. If you have ever blown a brake line on your car or pickup you’ll notice that it pretty much blows all the fluid out and you are barely able to stop. Imagine if you where rolling with 80,000 or like we do in Mich. and drag around up to 164,000 lbs gross and that happening. Wouldn’t be good I suspect
@Bendigo1 Жыл бұрын
That is not the only reason. It is easy to disconnect and connect airlines to a trailer but hydraulic lines are difficult to connect or disconnect without getting air in the lines that could cause serious issues with the effectiveness of the brakes. Another reason is that hydraulic brakes lose pressure with distance from the pump system. Another reason is the pressures required to activate the brakes with enough force to stop a vehicle that heavy.
@numbzinger350 Жыл бұрын
Air compresses to the point that relays are needed to quicken the response of an air brake system. That's why 'brake lag distance' is covered in the CDL manual. With air brakes on a semi at 55 miles per hour it takes 32 feet for pressure on the brake pedal to translate to pressure on the brake drum or disc. In a hydraulic system it's instantaneous. Hydraulic brakes are actually 'faster'.

Air is not faster than hydrolic. Air moves in the system up to 340m/s, while hydrolic moves.with about 1500m/s. So air os actually quite a bit slower. The benefit of air is.. that it is air. That is you can relise it with no problem. Say you would have a trailer, if it had hydrolica you would spil some every time you disconected. You could also taint the hydrolic system of the tractor unit.

I hate when I get into a truck that does not have full spring brake chambers on all axles except the steer axle, of course! Why, bcuz I hate pancake brake chambers, which is just the side for the service brakes, and no spring side for emergencies and the parking brake, for those who don't know! The problem is bcuz when you're loaded and you only have two spring brake chambers on one drive Axle, and two pancakes on the other drive Axle, the truck tends to roll forward when you pop the tractor brakes, especially on a slight incline. It's always better to have all spring brake chambers on all axles that require them! I feel super unsafe with pancake brake chambers. Then what if I need to pop the brakes while moving for whatever reason and I really need to stop? Those pancakes will do me literally no good for stopping in that emergency. That's the point in having spring brake chambers! Anyone who uses pancakes is clearly just cheap and shouldn't have a truck, in my opinion!

That truck and trailer will come to a stop just like it does when you apply the service brakes. It's not gonna instantly come to a violent stop. It's gonna keep rolling till all of the momentum is lost, but slower and slower as that momentum reduces. Now, on a slippery surface or a very high rate of speed, I wouldn't want to try that, bcuz i dont know how that would play out, lol.
