The modern car braking system has come a long way. From its original structure as a mere mechanical device to a technologically advanced system, modern brakes have become safer and smoother. These braking systems are designed for effectively stopping or slowing down the vehicle and are available in various types. Each brake type has its own set of features, advantages, and disadvantages. Understanding how these braking systems work is essential to ensure a safe driving experience.
Let’s talk about the most common types of car brakes and how they function.
Various types of braking systems in cars
Most modern vehicles have the following types of braking systems for optimal safety:
- Hydraulic braking system
The hydraulic braking system is a primary system used in most cars. Its working principle involves the use of brake fluids that help move other components like brake pads or shoes to generate friction against the wheels, effectively slowing down the vehicle.
Hydraulic brakes have a simple mechanism. Once you engage the brake pedal, the brake fluid flows towards the master cylinder to create hydraulic pressure. This pressure pushes the brake fluid to the wheels through the brake lines. This fluid then pushes the friction material against a brake or rotor drum. The friction generated between the components and the wheel’s kinetic energy is converted into heat energy, which slows the vehicle.
- Mechanical braking system
A mechanical braking system consists of parts that transmit braking force to the brake drum or disc rotor through linkages. It includes a brake pedal, drum or disc brakes, along with linkages such as cylindrical rods, fulcrums, springs, etc.
Due to its inefficiency, the mechanical braking system is now used only in parking or emergency brakes.
- Anti-lock braking system
Anti-lock brakes (ABS) were developed in the 1950s and became a standard in the early 1990s. Since then, it has become a critical safety feature in all modern automobiles. The anti-lock braking system uses sensors that adjust the brake pressure so you can get maximum control over your steering. It prevents skidding by stopping the wheels from locking up during hard braking and falls within the hydraulic systems category.
- Regenerative braking system
The regenerative braking system is commonly used in hybrid and electric vehicles. Here, the electric motor restricts the spinning of the wheel and captures the car’s kinetic energy to recharge the batteries powering the motor. This system starts slowing down the vehicle whenever you press the pedal or merely take your foot off the accelerator. While regenerative brakes perform most of the function, hydraulic brakes are still used for emergency stops.
The common types of brakes:
In addition to different braking systems, there are different brake types in cars. Each of these has separate working mechanisms.
The drum braking system was the first type of in-wheel brake. It consists of a wheel cylinder, a hollow drum, and brake shoes that are attached to the wheel. When you engage the brake pedal, the wheel cylinder pushes the brake shoes against the drum’s inner surface. This creates friction between the two surfaces, causing the wheel to slow down or stop.
Disc brake systems are the most common brake types used in modern vehicles. This braking system involves components such as a calliper, rotor, and brake pads. The brake rotor is fitted directly to the wheel and rotates along with it. When you engage the brake pedal, brake fluid is sent to the calliper, which squeezes the brake pads against the rotor. This creates a friction force that slows down the wheel and stops your car.
They are more effective and reliable during emergency stopping situations, manage heat better, are easy to maintain, and have greater braking efficiency on wet roads.
Also known as parking brakes or hand brakes, emergency brakes are independent of the hydraulic braking system. It acts as a secondary braking system if the main brake stops working.
It works through a manual pedal, lever, or switch. When you engage the hand brake or push the parking brake button, it locks your rear wheel. This prevents any movement, especially when parked on an incline. It also helps preserve the primary braking system by reducing strain on it.
Conclusion
Familiarising yourself with different brake types and their working is important for safety. Regular maintenance of the braking system ensures optimal performance and longevity. Besides maintenance, it is also important to invest in reliable car insurance to protect your vehicle from risks. Look for car insurance online and opt for a policy that provides financial coverage against accident repairs, theft, medical bills and third-party liability.
