It's called rolling friction.

I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
By reducing the coefficient of friction between the brakes and the wheel OR between the road and the wheels.
Yes? This isn't much of a question but there IS friction between a wheel and the road. The friction between the tyre rubber and the road surface stops the rubber moving with respect to (wrt) the road when force is applied, allowing the vehicle itself to move. Some of the energy is dissipated as heat. During acceleration the boundary relationship represents 'inertial frame transition', and when in constant motion the wheel and bearings form the boundary between inertial frames.

The friction between the asphalt on the road and the rubber tires cause a screeching sound, due to the sudden stopping of the wheel motion. The sound is caused because the tire has overcome static friction, and is now in sliding friction between it and the road.
Friction between the tires and the road. Without that kind of friction, we'd never be able to start moving, and wouldn't be able to stop!
No steering wheel won't provide the centripetal only the friction between the tyre and road provides the necessary centripetal. Steering would simply turn the wheels of the car to the desired direction.
friction is that force that opposes motion. for e.g friction between the road and your shoes prevent you from falling when you walk on the road.
Sliding Friction
Friction between the brake pad/lining and the rotor/drum and friction between the tyre and the road.
the friction is between the tyres of cycle and the road surface. Without friction movement is impossible.
