They are divided into two types of fundamental systems: Hydraulic systems and those based on friction materials. In hydraulic systems, when the brake of the vehicle is pressed, a master cylinder inside the engine is responsible for driving brake fluid through a tube to the brakes on the wheels, the pressure exerted by the liquid produces the necessary force to stop the vehicle. The pads are metallic or ceramic pieces capable of withstanding high temperatures and are responsible for creating friction against a fixed surface (which can be drums or discs), thus achieving braking of the vehicle; The ballasts are replaceable parts that suffer from wear and should be checked and changed periodically.
Types Of Hydraulic
Disc brakes consist of a rotor attached to the wheel, and a caliper that holds the brake pads. The hydraulic pressure exerted from the master cylinder causes a piston to press the pads on both sides of the rotor, this creates enough friction between the two parts to produce a decrease in the speed or the total stopping of the vehicle. While Drum brakes are consist of a metal drum attached to the wheel, a wheel cylinder, pickups, and return springs. The hydraulic pressure exerted from the master cylinder causes the wheel cylinder to press the pads against the inner walls of the drum, producing the corresponding decrease in speed. Currently, these brakes are used on the rear wheels and with certain vehicles, since the disc brakes enjoy a greater braking force so they are used in lots of cars as front brakes.
ABS Brakes & Handbrake
Anti-Lock Brake System or Brake Anti-Lock System, is a mechanism installed in the braking system of vehicles that prevents the immobilization of the wheels when the driver applies the brake sharply. Each of the wheels has a sensor that determines the revolutions and detects when a wheel decreases the number of turns compared to a predetermined value. The ABS system orders the reduction of the braking force and prevents blocking. While, the handbrake or parking brake prevents a parked vehicle from moving on its own, even when this system can be used, as an emergency brake during the vehicle's running. It consists of a lever or pedal that is within reach of the driver; connected by a metal cable to the brake cam. When operating it, the cams exert pressure on the ballads of the rear wheels causing braking, which in case of occurring while the vehicle is in motion, can be quite abrupt. One should very careful about the brake status and its quality before pay the Lexus rx 450h 3.5 price, or when he picks any used vehicle for use.
The Innovation Process
Some experts point out that disc brakes will soon go down in history because of the continual innovation process in the auto sector. The advantage of the new systems lies in their ability to respond to wet or dry pavements, stability in braking, the lower weight of the assembly and the long life of the discs. The technicians visualize a promising future for the ceramic brakes since they can be mounted in the current system, replacing the discs and the brake pads, without it being necessary to change the pistons, the servo mechanism or other components of the braking equipment.
