Now that you know the main components of an automotive braking system, how about learning how they work together to reduce speed and stop the vehicle? To understand the basic operating principle of the system, let's use the example of a standard vehicle, with the disc brake at the front and the drum at the rear — a model found in most cars sold in Brazil. When pressing the pedal, the movement is transferred to the brake servo via a lever. It then amplifies and delivers the generated force to the master cylinder. Once this happens, the hydraulic fluid is pushed and directed to the other components through the system piping. After the master cylinder stage, the brake works in two different ways, depending on the model. Drum brake Hydraulic fluid pushed by the master cylinder is sent to the wheel cylinder. Then, it activates a pair of pistons connected to the brake shoes — on which the linings are installed.
In turn, they are forced against the inner wall of the drum, causing the speed of the wheels to be reduced. When releasing the brake pedal, a system of springs forces the pistons and shoes to return to their original positions, freeing the Chinese Singapore Phone Number List wheels to rotate normally. Disc brake In the disc brake system, hydraulic fluid is sent to the piston (or caliper pistons). They force the pads against the disc, generating a lot of friction — necessary to reduce wheel speed. In each caliper, there are two pads positioned one on each side of the disc and aligned with each other. When the brake pedal is released, the fluid stops exerting force on the caliper pistons and the pads are moved away from the disc. Hand brake As it is a safety device, it must work independently of the hydraulic braking system. When the handbrake lever is pulled, it activates a steel cable, which is connected to the brake shoes.
In turn, they are moved and press the canvas against the drum wall — even if the pedal has not been pressed. When the handbrake lever is moved downwards, the steel cable is released, the shoes are no longer forced against the drum and the wheels are free to turn. Air brake Last, and not least, we have the truck brakes. Also known as pneumatic braking systems, these designs work with compressed air, delivering rigorous deceleration compatible with the vehicle's weight. As for how it works, it all starts with the air compressor. This component admits air parallel to the engine. Then, the compressor maintains this air with a high compression ratio and shoots it to the regulator — the component responsible for managing the pressure and intensity for the brakes to work.
