About Hydraulic Car Brakes

The braking system in a modern car is hydraulic. Force from the driver's foot is transferred to the brake pads on each wheel. When the brake pedal is pushed, pressure builds up in a master cylinder. This pressure is transmitted through a system of pipes to slave cylinders, so that the braking force is evenly spread each over of the four wheels. There are two types of brakes on modern cars, some cars have disc brakes fitted to the front wheels and drum brakes to the rear wheels. Other cars have disc brakes on all four wheels.In drum brakes, a brake shoe is forced against a brake drum which is attached to the wheel. Friction between the two forces the wheel, and hence, the car to slow down. When the brake pedal is pushed down, fluid from the master cylinder is pushed along the pipes to each wheel. In the slave cylinder, the pistons are forced apart, pressing the brake shoe against the brake drum. When the brake pedal is released, a spring pulls the brake shoes off the drum, and the pistons in the slave cylinders are pushed back together. This forces the fluid back along the pipes to the master cylinder.
