How does your car transmit the braking forces to wheels?
How does it multiply the force so that it is enough to stop a large car?
When you press your brake pedal, your car transmits the force from your foot to the brakes through a fluid. Since the actual brakes require a much greater force than you could apply with your leg, your car must also multiply the force of your foot. It accomplishes this through he use of hydraulic force.
The system is comprised of a master brake cylinder, metal brake lines, and braking cylinders at each wheel. By using your foot to compress the fluid in the master cylinder (with the assistance of a power booster), you transfer that force through the fluid in the metal brake lines to the brake wheel cylinders which either expand the brake shoes against the brake drum (in a drum braking system) or compress the brake pads against a rotating Disc (in a disc brake system).
Once that braking action occurs, the braking energy is transferred to the tires, where tire construction components and tread pattern apply the friction to the road to stop the vehicle.
Some signs that your brakes need servicing are obvious, like the brake light appearing or the feeling that your vehicle is taking longer to stop than it should.
Here, are five steps that just may help you avoid a serious accident in the future.
