This is an emergency brake, the brakes WILL catch on fire after it's been performed and are almost always replaced for the next flight. This was a very successful test.

+Rikyy The brakes used for these Rejected Take Off tests are old worn out components that shouldn't be used on a properly maintained jet.. The purpose of this test is to get the plane stopped in worse case scenarios. Worn out brakes, max takeoff loading, no thrust reversers, no external cooling of the brakes/wheels/tires by firefighters until 5 minutes after the planes comes to a stop. The brakes are always replaced after these tests because the brakes that are installed for these tests aren't flight worthy to begin with.

+Hudson Ball Could be wrong but I'm pretty sure thats the tires automatically deflating, if I remember right the rules are it has to land fast [or i guess in this case reject a takeoff] and stop without thrust reversers and maximum weight, then sit for 5 or 10 minutes or so [i can't remember exact time, its supposed to represent the maximum time it would take for a fire engine to respond] without any of the tires exploding, then after that time period remote valves are opened on the tires so they deflate before they explode, I guess they would eventually explode if left exposed to that heat for a long time

The rules are it has to stop in so many feet with the brakes at the minimum allowable thickness (basically as worn out as they could be), they weren't allowed to use the thrust reversers and had to stand or taxi for 5 minutes without going up in flames. On the 777 after the tires fuse plugs melted and they put out the glowing brakes, it cost $750,000 to replace the entire gear because of the heat, course thats change to the price tag of replacing the plane and the lawsuits that would happen from passengers

Mark S, that is correct , tires are charged with dry nitrogen. Fusible plug cores typically melt at 177 degrees C,( but there are other different rated plugs) Following a RTO which is the most severe braking an aircraft can subjected to, the overheated brakes (understatement !) transfer heat to wheel assemblies and tires. The normal tire pressure can be 150 to 225 PSI depending on aircraft type and a RTO can increase pressure dramatically, coupled with tire degradation due to the heat an explosive situation could occur, multiple plugs are mounted on wheel assemblies. These allow tire pressure to dissipate to avoid aircraft damage (fuel tanks) and injuries to persons.

Brakes don't light on fire when you don't use your T/R's, but they will if you do a rejected take-off with a fully loaded plane and not use T/R's. This is a test for RTO, worn out brakes must stop a fully loaded plane.

always wondered why they couldn’t build in a fire suppression system that would disperse foam or nitrogen or something through a set of nozzles on the inside of the wheels to put out the brake fire after a RTO, since fire is certainly always expected after that, instead of someone on the ground crew having to drive over to the plane and put it out manually.

No room for disc brakes on passenger jets. They use drum brakes, and the drum (rotor) is an integral part of the wheel rim. It's the most compact and lightweight arrangement possible, and works just fine in normal use. This video is a test of a rejected takeoff (RTO) which is an extreme example of brake use in a passenger jet. The brake pads and wheel rims become extremely hot, and the tire pressure is vented automatically to keep the tires from bursting. That's what you see after the plane stops and you get puffs of smoke coming from the wheels.
