hovercraft work on the principal of friction less disc then how the apply brakes?

Answer 1

Traditional hovercraft have limited "braking" power
Some use "skirt drag" or deflate the front cushion to lower the nose, Reduce power until there's no "hover" (not recommended - can make a mess of the skirt" or swing it around 180 degrees & give it full thrust - thrustpower acts a s a braking system.
Newer hovercrafts are being produced with a reverse thrust system for more effective braking.

When in motion, hovercraft brakes by throwing air in the direction of movement causing a higher pressure buildup in front of the hovercraft resulting in a reverse thrust.
