Drum Brakes
Drum brakes are the most common type of brake system in cars. They consist of a brake drum, which is attached to the wheel hub, and a brake shoes, which press against the drum to create friction and slow down the vehicle. The brake shoes are connected to the brake pedal via a series of cables and levers.
Disc Brakes
Disc brakes are less common than drum brakes but are becoming more popular in modern cars. They consist of a brake disc, which is attached to the wheel hub, and a caliper, which clamps down on the disc to create friction and slow down the vehicle. The caliper is connected to the brake pedal via a series of cables and levers.
Brake-by-Wire Systems
Brake-by-wire systems are a newer type of brake system that use electronic sensors to control the brakes. These systems eliminate the need for physical cables and levers, making them more reliable and easier to maintain.
Brake System Components and Operation
The brake system in a car consists of several components, including the brake pedal, master cylinder, brake lines, and wheel cylinders.
Brake Pedal
The brake pedal is the part of the brake system that the driver presses to activate the brakes. When the brake pedal is pressed, it pushes a rod that activates the master cylinder.
Master Cylinder
The master cylinder is a hydraulic device that pressurizes the brake fluid and sends it to the wheel cylinders. The master cylinder has two chambers: one for the brake fluid and one for the brake pedal rod. When the brake pedal is pressed, the rod pushes the brake fluid into the first chamber, which then pressurizes the fluid and sends it to the wheel cylinders.
Brake Lines
The brake lines are tubes that carry the pressurized brake fluid from the master cylinder to the wheel cylinders. The brake lines are made of flexible rubber or plastic and are designed to withstand the pressure of the brake fluid.
Wheel Cylinders
The wheel cylinders are hydraulic devices that press against the brake shoes or brake disc to create friction and slow down the vehicle. The wheel cylinders are activated by the pressurized brake fluid that is sent from the master cylinder through the brake lines.
4. Steering System
