Braking System

The document provides an overview of the key components of a vehicle braking system and their functions. It discusses the master cylinder, brake servo/booster, brake caliper, drum brake, brake pad, brake shoe/lining. The master cylinder converts pressure from the brake pedal into hydraulic pressure. The brake booster amplifies the force from the pedal using vacuum assistance. The brake caliper houses the brake pads and pistons. Drum brakes are commonly used on rear wheels. Brake pads convert kinetic energy to thermal energy through friction. Brake shoes slow the drum inside the wheel. Hydraulic bleeding removes air from the brake lines.

Braking System

BRAKING SYSTEM
Objectives
A vehicle brake is used to slow down a vehicle by converting its kinetic energy into heat. The basic hydraulic system, most commonly used, usually has six main stages. The brake pedal, the brake boost (vacuum servo), the master cylinder, the apportioning valves and finally the road wheel brakes themselves.

THE VEHICLE BRAKING SYSTEM

FOOT BRAKES & PARKING BRAKES

1 Parking Brake Rear Cable and Conduit 2 Rear Drum Brake 3 Rear Disc Brake 4 Front Parking Brake Cable and Conduit 5 Parking Brake Lever

THE COMPONENT AND THE FUNCTION OF THE COMPONENT

MASTER CYLINDER
The master cylinder is a control device that converts non-hydraulic Pressure (commonly from a driver's foot) into hydraulic pressure, in order to move other device(s) which are located at the other end of the hydraulic system, such as one or more slave cylinders

BRAKE SERVO/BOOSTER
The brake booster usually uses vacuum from the engine intake to boost the force applied by the pedal on to the master cylinder, or may employ an extra vacuum pump to enable it. Without the engine running the brake pedal feels very hard and ineffective on the braking capability.

BRAKE CALIPER
The brake caliper is the assembly which houses the brake pads and pistons. The pistons are usually made of aluminium or chrome-plated steel. There are two types of calipers: floating or fixed.

DRUM BRAKE
Drum brakes are used in most heavy duty trucks, some medium and light duty trucks, and few cars, dirt bikes, and ATV's. Drum brakes are often applied to the rear wheels since most of the stopping force is generated by the front brakes of the vehicle and therefore the heat generated in the rear is significantly less. Drum brakes allow simple incorporation of a parking brake

BRAKE PAD
Brake pads convert the kinetic energy of the car to thermal energy by friction. Two brake pads are contained in the brake caliper with their friction surfaces facing the rotor. When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together into the spinning rotor to slow/stop the vehicle.

BRAKE SHOE / LINING


The drum brake has a meter brake drum that encloses the brake assembly at each wheel . Two curved brake shoes expend outward to slow or stop the drum which rotates with the wheel.

HYDRAULIC BRAKE BLEEDING

Brake bleeding is necessary because, while the brake fluid is an incompressible liquid, air bubbles are compressible and their presence in the brake system greatly reduces the hydraulic pressure that can be developed within the system. The same methods used for bleeding are also used for purging, where the old fluid is replaced with new fluid, which is necessary maintenance.
