A car's brakes use sliding friction. In most modern cars there is a disc attached directly to the wheel and tire. When the tire is spinning this brake disc is also spinning. When the brake pedal is pressed, fluid is pushed through a line, filling a chamber with very high pressure. As this chamber expands it causes the brake pads to clamp down on both sides of the brake disc, using friction to slow the rotation of the tire, which, in turn slows the car's speed.
Sliding Friction . . . Hoped I Help!! God bless :)
surface friction and sliding friction
For almost all materials, sliding friction is less thanstatic friction.It's why it's hard to get out of a skid in a car.
Sliding Friction
The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.
Friction is a force between to surfaces that resists motion. Static friction is the resistance to motion when two surfaces are not moving relative to each other. Sliding friction is the resistance to motion when two surface are sliding, one over the other. Sliding friction is less than static friction for the same two surfaces. For rolling friction an object is rolling, like a tire on a road. It's what provides traction between the two and makes the car "go." For a tire on a road, rolling friction is less than sliding friction.
Sliding Friction If you push hard enough on the cardboard box filled with books, it will start sliding. If you stop pushing after the box starts sliding, it will slow down and stop. The force that acted on the box to slow it down was sliding friction. Sliding friction is the force that opposes the motion of two sliding surfaces in contact. Sliding friction exists between all sliding surfaces that are touching, such as the surfaces of the moving parts in a car's engine.
Antilock Brake System (ABS) & tread on the tires.
Sliding friction is the friction between the body and the surface on which the body is sliding. Static friction however, is the friction when the body isn't moving when you aply force to it. The force of static friction is the same as the force you are pushing the body UNTIL it moves!..It's a fact that the static friction coefficient is a bit bigger than the sliding friction coefficient.
The three types of friction are static, sliding and rolling I'll use a car to illustrate these three types. If you try to push your car sideways (push on the passenger or driver's door) and it won't move, the force between the tires and the driveway ( or whatever surface the car is on) that prevents the car from moving is static friction. If you're driving down the highway and apply the brakes but not enough to stop the wheels from rolling, the force between the tiers and the highway that is slowing the car is rolling friction. If you slam on the brakes and lock the wheels so they are sliding/skidding down the highway the force between the tires and the highway that will eventually bring the car to a stop is sliding friction.

Static: A cars wheels (while car and wheels are stopped, or while car is moving and wheels are rolling), a doorstop, a rock on a hill (not sliding down) and the force keeping a nail in some wood. Sliding: A cars wheels (during burnouts or when brakes are applied too hard and the car skids), dragging a computer mouse along a table, Ice skaters blades and a drink slid down the bar to you.
