When large jets land they reverse engine thrust to brake. After they land and are driving around the airport how do they stop?

Yes.

They have brakes that can be operated individually, to aid in the steering. Building heat in the discs and calipers IS a big deal, which is why they also use speed brakes on the wings, thrust reversers, and flaps. The brakes are built as small as possible because brake components are heavy.

Yes they have brakes on the main wheels (the sets on the sides of the planes) but not on the nosewheel. They control them by 2 brake/rudder pedals, controlled by the pilot's feet (much like a brake pedal on a car). If the pilot presses on the top of right pedal, only the right brakes are engaged, and the same holds true on the other side. They are assisted in landing by reverse thrust, and spoilers.

YES. Aircraft do have brakes on their main wheels but not on the nose wheel. Thrust reverser is used to attain efficiency when braking. They use the brakes to stop the aircraft during taxiing.

They use multi rotor disk brakes with anti-skid, and they do use them when landing along with the T.R.s.
If they didn't use brakes, the runway would have to be very long to stop with the T.R.s alone.
As mentioned above, the nose gear is turned for steering on large aircraft, using hydraulic actuators to assist (power steering).
Nose gear DO NOT have brakes. The structure holding the gear (trunnions) or the gear itself would not handle the extreme force of all that weight transfer when the brakes are applied.

Passenger jets certainly do have brakes on their wheels. Actually, it's from the braking systems on aircraft landing gear that the idea for anti-lock brakes on cars was developed.

Yes they do have brakes. In fact an auto braking system is used for take off in case of a rejected take off and 1-4 conditions for normal landing.

Yes I have seen them. A long time ago a friend worked for TWA.
a 747 has about 4 or 5 stacks like brake discs. Looks kinda like pancakes. On your car you have one brake disc, and one to two brake calipers. The 747 has many calipers per disc. I counted and it seems like there were 96 calipers in all on all the discs. Also they don't have to worry about heat as much as the brakes only have one BIG stop before having a chance to rest. PS they also have anti lock brakes too.

Yes they do have brakes on the main gear and contrary to what others are saying, many frequently do have brakes on the nose gear. Antiskid too.
The nose gear is steered by a wheel or a tiller bar in the cockpit and also the rudder pedals have limited ability to steer the nose wheel itself.

yes they do. and they use them too on landing. reverse thrust are used only to assist in the braking.

Yes, except nose wheel all wheels have brakes ........ with anti skid and anti locking protections build in ........... it even has option for manual braking or automatic braking on touch down after landing ........... however during taxi on ground it is manual .......... you have the reading of brake temperature of each wheel and option to put on the brake fans to cool them down in modern jet ........
