The air compressor on an air brake equipped vehicle is exactly the same as an air compressor you would find in a garage. The only difference is that an air compressor on an air brake equipped vehicle runs the entire time the motor is running; therefore, it is controlled by the governor. The governor controls the maximum and minimum setting of the air compressor because the air compressor is capable of pumping up to 500psi (pounds per square inch). The governor must return the air compressor to the load or cut-in phase by a minimum of 80psi. And it must return the air compressor to the cut-out or unload phase by a maximum pressure of 135psi. All air brake systems are equipped with a safety valve, which blows off excess pressure at 150psi. You will know it is the safety valve because it makes a sound like a machine gun. The air tanks or reservoirs store compressed air. As well, the air tanks are the first fail-safe of the air brake system because these store enough compressed air for 10-12 full service brake applications. The air lines direct compressed air through the air brake system. The air lines are not coloured coded except the service and supply lines that connect the semi-trailer to the tractor or truck. The brake pedal applies the service brakes, which are the brakes that bring the vehicle to a stop while it's going up and down the road. And the foundation brakes are the components of the air brake system that are actually responsible for bringing the vehicle to a stop: • brake chambers • push rod • slack adjuster • 'S' cam • brake shoes (pads) • brake drum • rotor • callipers And the foundation brakes can be any of the following; however, drum and disc brakes are most common on today's vehicles: • drum ('S' cam) brakes • disc brakes • wedge brakes • CamLaster brakes • air-over-hydraulic brakes The foundation brakes—in this day & age—will be 2 basic types: drum or disc brakes. Foundation brakes also consist of air-over-hydraulic and wedge brakes - you will need to know the latter for the purposes of the air brake knowledge test.

Air Brakes - An Introduction. How it works.


This video gives an introduction and brief look at air braking systems on heavy and commercial vehicles. You'll see from the animations that all systems have a compressor to supply the air, reservoirs to store the compressed air, controls for the driver to direct the air (foot and hand brake) and actuators and friction brakes to actually carry out the braking. This video sticks the the fundamental basics of the Air Braking System and doesn't go as far as other system components such as s-cams, relay, quick release and trailer control valves, air dryers and filters, protection valves and other system operations. We'll go into depth with these in further videos.

How to Determine Air Brake Adjustment—Applied—Pry Bar—Mark & Measure


For both a road test & your daily pre-trip inspection you must determine if the air brakes are in adjustment. Watch the video! CDL IN-CAB Air Brake CHECKLIST: 🤍 SUBSCRIBE TODAY! ► 🤍 #cdlairbraketest #smartdrivetest #airbrakepretripinspection Get 30% OFF Air Brake Course. Coupon "youtube30" CLICK THE LINK 🤍 Adjustment Limit Chart: 🤍 Depending on where you're taking your CDL licence, you are required to check air brake adjustment. Either the pry bar or the applied stroke method will be required. Most jurisdictions use the pry bar method to determine if the air brakes are in adjustment. Safety first: chock the wheels, release the parking brakes and ensure that the system air pressure is above 90 psi (620 kPa). If using the pry bar method, you'll require a pry bar. Using a pry par, force the push rod out of the brake chamber. The push rod should not extend out of the brake chamber more than 3/4 of an inch, or the width of your thumbnail. In New York & the state of California, they allow 1" inch of travel using the pry bar method. Other jurisdictions, such as Ontario in Canada, require that license examinees use the applied stroke method. Again, chock the wheels, release the parking brakes and ensure the system air pressure is above 90 psi. Mark all the push rods at a fixed point - usually the face of the brake chamber. Apply the service brakes and hold - either get someone to hold the service brakes in the applied position or use a stick, or other device. After applying the service brakes, measure from the fixed point out to the mark on the push rod to determine if the air brakes are in adjustment. With automatic slack adjusters on a Type 30 brake chamberwhich are the most commonyou are allow 2" of push road travel. In the rare case that you have manual slack adjusters, the push rod is allowed to extend out of the brake chamber 1 3/4" inches. The amount the push rod is allowed to extend out of the brake chamber is determined by brake chamber size, and the size of the brake chamber is determined by its diameter. If the brakes are out of adjustment, and the vehicle is equipped with automatic slack adjusters, you can attempt a "6-pack" to bring the brakes back into adjustment. Pump the system to maximum pressure, make 3 full, hard brake applications. Pump the system's air pressure back to maximum and make 3 more full, hard brake applications. Often this will bring the brakes back into adjustment. If not, the vehicle will have to be brought to a mechanic for repair. Good luck on your road test! 🤍smartdrivetest.com 🤍facebook.com/smartdrivetest 🤍twitter.com/smartdrivetest

Air Brakes Explained Simply :: Service, Parking and Emergency Brakes One & the Same


The brakes on your car are the same as air brakes, only the power source is different - watch the video. CDL IN-CAB Air Brake CHECKLIST: 🤍 SUBSCRIBE TODAY! ► 🤍 Get 30% OFF Air Brake Course. Coupon "youtube30" CLICK THE LINK 🤍 On a hydraulic braking system that is fitted to most passenger vehicle, there are three brake types: 1) service brakes (brake pedal) 2) parking brakes 3) emergency brakes. All braking systems are divided into two independent sub-systems, therefore it is rare that service brakes fail. When you're going up and down the road, you apply the foot pedal and the vehicle comes to a nice gentle stop. Or if you find yourself in an emergency situation, you have the brake pedal and the vehicle comes to a screeching halt. Although 85% of vehicles in North America are fitted with automatic transmissions and 90% of those drivers don't use the parking brake, all vehicles have parking brakes. And drivers should use the parking brake to prevent undue wear on their transmission when the vehicle is left parked. And in the event that the brakes fail going up and down the road and the brake pedal doesn't work, the driver can apply the parking brake. When the brakes fail and the driver uses the parking brake to bring the vehicle to a stop, the parking brake is now an emergency brake, becauseoddly enoughit is now an emergency situation. Ai brakes have the same three types of brakes: 1) service brakes (brake pedal) 2) parking brakes 3) emergency brakes. What has confused students since air brake courses were implement in the 1970s is that instructors refer to service brakes as air brakes and spring brakes as parking and emergency brakes. There has not been a clear terminology, and this lack of clarity has served to confuse air brake students. So, the three brake types are the same. What is different is that power source that applies the brakes. On a hydraulic system, hydraulic pressure applies the service brakes. The parking/emergency brakes are applied with a cable and lever. The energy to move the lever comes from the driver. The only difference between the brakes on a hydraulic system and those on an air brake system is the power source and that the emergency brakes on your car are applied manually - on an air brake system, the emergency brakes apply automatically. On an air brake system, the driver pushes the brake pedal and applies the service brakes going up and down the road. When the driver parks the vehicle, she/he pulls the parking control valve on the dash and exhausts the air from the spring brake chamber. Exhausting the air pressure allows the large, powerful springs to expand which applies the parking brakes. While the vehicle is going up and down the road, the large powerful springs are held in the released position by air pressure. If the air pressure is lost, the large powerful spring will expand and begin to automatically apply the emergency brakes. Both hydraulic and air brake systems are the same. Both have parking brakes where the parking/emergency brakes are one and the same. The only difference is that the emergency brakes on your car are applied manually and on an air brake system these apply automatically. What has confused students is referring to parking/emergency brakes as spring brakes.

The five main components of an elementary air brake system and their purposes are: Compressor: to build up and maintain air pressure Reservoirs: to store the compressed air Foot valve: to draw compressed air from reservoirs when it is needed for braking Brake chambers: to transfer the force of compressed air to mechanical linkages Brake shoes and drums or brake rotors and pads: to create the friction needed to stop the vehicle Pneumatic brake system An air operated brake system or pneumatic brake system is employed predominantly in medium and heavy duty trucks, because of the following advantages. 1. The pressure of the precompressed air allows practically any force required for braking to be developed with a very small effort applied by the driver to the brake pedal. 2. The compressed air can also be used to inflate the tyres, drive the windshield wiper, actuate steering gear booster, open and close doors in buses etc. 3. An air operated brake is the most dependable and convenient device for braking full trailers and semitrailers.

Learning to fly the Carbon Dragon - Flying with the air brakes fully open... and an out landing!


Incident Report (Abbreviated) Date / Time : 10 August 2019 - 13:15 Location : Aspres-sur-Buech Aerodrome, France Summary : Pilot launches on aero-tow with air brakes fully open. Pilot is forced to do an emergency out landing. Landing Field : 44.518875, 5.717236 Damage / Injury: None. Reason : Pilot failed to complete his full pre-flight check list. I had arranged to tow up with tow pilot Philippe at 13:30 and was waiting on the launch point with my glider for the tow plane (piloted by Francis) to return to the airfield. I was chatting to Philippe when I saw the Tetras on downwind, and started to get into my glider and sort myself out, still expecting Philippe to change places with Francis and tow me up, so I was not in a rush at that time. The Tetras landed and turned around in front of me, and the heavier sailplane tow rope was exchanged for the lighter PUL tow line. My glider was already connected to the PUL tow line. The Tetras then immediately started to take up slack, before I had even time to buckle into my glider harness, close my canopy or go through my pre-flight check list. I made a quick radio check with Francis to make sure he could hear me. I announced "Tendu - 2 minutes please" on the radio. Francis replied "Hurry up, my engine is getting hot", which placed enormous pressure on me to finish my preparations (harness buckles, arm the rocket parachute, close my canopy, check my controls for full and free movement, set flaps to 5 degrees and, critically, close my air brakes.) By the time I had my canopy closed and secured, the tow aircraft was beginning to pull me forward very slowly, and I abandoned my partially completed pre-flight checklist in order to put my hands on the controls and tow release, and I stupidly signalled/radioed that I was ready. This was my mistake. I should have disconnected from the tow line and radioed the tow pilot to turn off his engine and wait for it to cool down. I should not have allowed myself to be pressured into taking off before I was 100% ready. The tow started normally, but I found the air to be much more turbulent than I expected, and the response of the glider in roll was diminished. There was also significantly more noise coming from the wings than normal. I released at 1450m amsl heading east along the south face of Apotre mountain and turned back west in sink. At this point I still didn't realise my air brakes were fully open, even though the glider had a slight pitch down tendency and handled a little sluggishly in roll - two characteristics of the air brakes being open - but I was still stressed from the turbulent tow and not thinking analytically. I continued to fly west along the ridge in the hope of finding stronger lift, but I was descending rapidly. At the corner of Apotre and Longeane I discovered that I was at 1250m amsl, much lower and descending much faster than I had realised, and I made my turn to return directly to the airfield, which is at 830m amsl. Just a few seconds later I found myself at 1100m amsl and realised I would not make it back to the airfield. I was in a state of disbelief, but rather than search for a reason, I concentrated on flying the glider. What was happening was happening, and I had to deal with it. Given my rapid descent rate (approximately -3m/s+) I quickly made the decision to land in the nearest lag field facing approximately into the prevailing wind (10-15kmh South South West). I set up my approach and, making my final turn, reached for the air brake handle only to discover that the air brakes were already fully open. I closed the air brakes and re-opened them to adjust my glide slope, and made a good approach with plenty of speed (~85kmh - my stall speed is ~40-45kmh) and landing into the up-sloping field. Touch down was smooth and controlled, and I rolled to a stop. No damage done. Lessons learned: 1 - I did not complete my pre-flight checklist, the last item of which is: Close the Air Brakes. 2 - This incident was entirely my fault. I allowed myself to be pressured into launching before I was 100% ready. 3 - The unintentional pressure placed on me by the tow pilot (who was concerned about his engine temperature) was a contributory factor to this incident. 4 - I should have released from the tow line and told the tow pilot I was happy to wait until his engine had cooled down. There was no rush on my part to launch. 5 - I will paint my air brake spoilers bright orange for next season to make them more obvious to both the tow pilot and the wing man. 6 - Once in the air, I did not associate the extra noise, pitch down tendency or reduced roll control authority with the air brakes being open. After releasing from the single most turbulent tow of my short 3-axis flying career, it took me some time to recover my composure and to relax, and I was concentrating on flying the glider rather than looking for a reason for my rapid descent rate.

Not a day goes by that we don't use something pioneered by George Westinghouse. He is the forgotten role model that our country needs today to teach future generations of Americans that hard work and kindness pay off. George Westinghouse was one of the most successful men in the world. A respected engineer, inventor and America's greatest industrialist. He was a pioneer of the industrial revolution and played a leading role in turning the United States from a young agrarian society into a modern economic powerhouse. The name "Westinghouse" has been a household name the world over for more than 100 years because of one man, his love of machines, and his desire to make the world a better place. The accomplishments that George Westinghouse had in his lifetime had a major impact on the way we live today. His work in the railroad industry with the Westinghouse air brake, the electrification of the world with Westinghouse alternating current, him being instrumental in developing natural gas as a fuel, and his impact on the shipping industry with the Westinghouse geared marine turbine engine. George Westinghouse was known as a good person. He always had a very good rapport with his workers. There was never a strike at any of the Westinghouse companies all the time he had control of them. And, you know, that was not common back in those days. He certainly was not motivated by greed or money. He really thought that his accomplishments would benefit mankind. And that alone was a driving force for him. This film also engages in the power struggle between Westinghouse and Nikola Tesla.

QRV's are fitted to an air braking system to speed up the release of air, as it takes longer for air to escape a system than it does to put it in there. The main applications for quick release valves are in the service line to speed up the release of the service brakes, and in the secondary circuit to speed up the application of the park/secondary brakes. With a similar purpose to the air brake relay, the QRV is just there to speed up the release of compressed air from the braking system.

How to Do the CDL Air Brake Pre-Trip Inspection


Inspection of air brakes is 'MUST KNOW' for a CDL license - watch the video! CDL IN-CAB Air Brake CHECKLIST: 🤍 SUBSCRIBE TODAY! ► 🤍 Get 30% OFF Air Brake Course.

The air brake pre-trip inspection can either be done independently or as part of the entire vehicle pre-trip inspection. For the purposes of a CDL (Commercial Driver’s Licence) in the United States, Canada and other countries you must be knowledgeable in air brakes. The air brake course consists of both a theory or knowledge and practical portion. The knowledge component of the air brakes is complicated by the fact that the air brake courses that are being taught are 40 years old. And because these air brake courses are 40 years old, everything and the kitchen sink are part-and-parcel of these courses. In the above video, we do a stand-alone inspection of the vehicle’s air brake components. The first steps of any pre-trip inspection are to chock the wheels, release the parking brakes, and ensure that there is more than 90psi (pounds per square inch) of air pressure in the system. When releasing the parking brakes, put your foot over the brake pedal in the off chance that the wheel chocks do not hold. The air brake pre-trip can be done in different sequences and that will depend on different driving schools. For this sequence, we inspect the air tanks first, and if it is an older system, you drain the wet tank first to ensure that the one-way check valves are working. If the one-way check valves are working, you know that the dual air brake system is also working. You then inspect all the components outside the vehicle starting under the hood on the driver’s side. And using the pry bar (free-stroke) method, inspect the adjustment of the air brakes. As well, your mantra for the inspection is: “secure, not damaged, not leaking.” Approximately 75% of the components in the vehicle have either air or fluid in them, so you say that the component is not leaking. After completing the inspection outside the vehicle and determining that all components are operational, you go in the cab and inspect: 1) governor (minimum & maximum settings) 2) low-air warning 3) spring brakes apply automatically 4) compressor (build-up) 5) leak test The last test for the air brake pre-trip inspection is to apply the parking brakes, remove the wheel chocks, and then do a tug test on the parking brakes and a response test on the service brakes. The last part of any pre-trip inspection is to fill out the paperwork, which is a legal document. And the pre-trip inspection form must be filled out as part of the driver’s daily tasks. 🤍smartdrivetest.com 🤍facebook.com/smartdrivetest 🤍twitter.com/smartdrivetest 🤍instagram.com/smartdrivetest/ #smartdrivetest #cdltraining #pretripinspection
