Car+brakes


 * Stop the car!**

Step on the brake pedal and the car comes to a stop. But there is more to it than that.
 * depress the brake pedal
 * hydraulic
 * transfer energy
 * calipers on the brake pad on the wheel
 * wheels on road surface
 * friction

The [|typical brake system] consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder.

But what if it is icy or slick with rain?
 * no traction
 * [|anti-lock braking system (ABS)] - a four-wheel drive system that prevents the wheel from locking through the monitoring of brake pressure. This gives the driver the ability to manage and control steering and stop within in a short distance. The goal of anti-lock braking is maximize braking power while simultaneously preventing the wheel from locking and skidding.
 * limited slip differential

Suspension - the system of springs, shock absorbers and linkages that connects a vehicle to its wheels.
 * leaf spring - used on cars up to about 1985 and almost all heavy duty vehicles. They look like layers of metal connected to the axle. The layers are called leaves, hence leaf-spring.


 * coil springs
 * torsion bars
 * shock absorbers
 * linkages


 * crumple zone
