Yes. Aircraft have wheel brakes just like the brakes on your car. The pilot operates them by depressing the tops (or toes) of the rudder pedals.
In addition, the flaps are used to slow the aircraft in flight, and many aircraft have air-brakes and/or thrust reversers to further aid in slowing the aircraft.
Airbrakes on commercial aircraft are hydraulically operated.
There are no bearings in brakes, but the hub has large ball bearings
Aircraft have disc brakes, but they're different from automotive disc brakes: the calipers are the same size as the rotors and they have pads going all the way around. On a really big plane, like an airliner, there are multiple discs.
The amount of runway needed form the time the brakes are released to the time the aircraft becomes airborne
A Flap is a control surface that is used to kill the lift of a wing to allow the aircraft to descend. I've never heard the term "body Flap" but it must refer to a Flap or a "speed brake" that is located on the fuselage and is used to slow the aircraft. Military aircraft used speed brakes or Dive brakes to slow their speed when diving on a target to drop a bomb. Some aircraft with fuselage speed brakes is the A-1 Skyraider propellor aircraft of Viet Nam and I think the F-86 jet fighter.
Check or test the brakes
All aircraft are fitted with brakes (much like a car) -however - with large aircraft, the pilot can set the engines to 'reverse thrust' which brings the plane to a stop quickly.
they use both. the aircraft uses ceramic brakes to slow the aircraft (ceramic because of the extreame heat produced up to 300 deg C). The rev thrust is mainly used to slow the aircraft at high speeds. rev thrust is disengaged when the aircraft hits about 80 knts and from then on the brakes are used only. If you get a good enough photo of the landing gear during braking they should glow red/yellow
A jet engine has no brakes. Though they do have thrust reversers which change the direction of thrust to slow the aircraft down. Aeroplanes have brakes on the wheels.
Most large aircraft have disc brakes located inside the rim of the wheel. Some aircraft with smaller wheels have brakes mounted next to the wheel rim. The brakes fit so precisely inside the wheel rim, that you may not know what to look for. The typical passenger aircraft brakes consist of a stack of rotors and stators. The rotors are plates with brake pads that attach to "keys" on the inside diameter of the wheel rim and rotate with the wheel. The Stators are attached to the hub of the brake and remain stationary and do not spin. The Rotors and Stators are alternated. When the brake pressure is applied, small hydraulic actuators compress the stack to rotors and stators against each other to create friction. If you go back and look at the first couple of episodes of the TV series "Lost", you will see some close up shots of their crashed airliner and there is no Brakes inside the wheels. (Obviously, the producer bought some surplus aircraft parts and didn't buy the brakes.)
Answer On "older" aircraft, the pilot applies brakes that moves cranks and pulleys that opens the Brake Valve. The Brake Valve ports regulated pressure to the Anti-Skid Manifolds. The Manifolds provides the pressure to the brakes. If the Anti-Skid computer detects a skid condition, the computer commands a pair of matching brakes to release pressure to allow the wheels to spin back up. The anti-skid releases brakes in pairs to keep an equal braking applied to each side of the aircraft. If the braking is unsymmitrical, this could cause the a/c to go into a spin.
That figure will vary from 25 to 100 feet. The figure depends on the operator or the airfield control.
