Braking systems in vehicles are a necessity. One cannot even comprehend what would happen without brakes. Brakes are probably the most important safety features on vehicles, and their evolution has been noteworthy. 

The earliest brakes used in vehicles were mechanical drum brakes. Since then, brakes have evolved to the modern ABS (anti-lock brake system) and the CBS (combined braking system). 

In this blog, we shall discuss the CBS braking system and find out how they are efficient than the ABS system of brakes. So, read on to find out more.

Understanding the CBS Braking System

To ensure your safety and that of other cars on the road and pedestrians, braking is a must-have safety feature in vehicles. This is where the CBS braking system comes into play.

CBS is a system of braking where an equal amount of force is applied to both the front and rear wheels of vehicles. Thus, the term “combined” arises from this system. The brakes on the CBS system are present in both the rear and front wheels. There is also a device called an equalizer present in the CBS system. The equalizer’s job is to distribute the force evenly on both the front and rear wheels. 

In real-world scenarios, when a biker presses the brake lever, CBS brakes are activated on both the rear and front wheels. The equal distribution of force prevents the rear wheels from lifting off the ground. This prevents fishtailing and skidding and improves stability in the vehicle. 

The CBS braking system is an important safety regulation in two-wheelers. Thus, it is most common in two-wheelers like motorbikes and scooters.

CBS vs. ABS: Which is Better?

Another type of braking system that is popular these days is the ABS or Anti-lock braking system and is an innovative braking mechanism. 

In ABS-enabled vehicles, there is a sensor present on each wheel. When the driver presses the brake, each sensor on the wheel determines the speed and amount of pressure on the wheel. The sensors then adjust the braking force accordingly.

Now, let’s compare both the ABS and the CBS braking systems.

1. Functionality

ABS prevents wheel lock-up during hard braking by rapidly modulating brake pressure. It monitors individual wheel speed and then adjusts the brake pressure to maintain optimal traction and steering control.

On the other hand, a combi braking system distributes the braking force between front and rear brakes to improve stability during braking. When the rider activates the brakes, both front and rear brakes are applied, and the CBS system manages the distribution of braking force which prevents the rear wheel of the bike from lifting off the ground.

2. Purpose

The primary purpose of ABS is to prevent wheel lock-up and maintain steering control, especially on slippery or uneven surfaces.

On the other hand, the main purpose of CBS is to improve stability and control by distributing braking force between the front and rear brakes.

3. Components

ABS requires sensors to monitor wheel speed and a control unit to modulate brake pressure. It may also involve hydraulic modulators to adjust brake pressure rapidly.

CBS typically involves a more balanced hydraulic or mechanical system that links the front and rear brakes.

4. Usage

ABS is more commonly used in 4 wheelers, while CBS is used more in two-wheelers like motorbikes and scooters.

The Benefits of the CBS Braking System

CBS Braking System

The CBS braking system provides a host of benefits, as discussed below:

1. Stability

The CBS braking system distributes the braking force evenly between the front and rear wheels. This prevents the rear-end tire from lifting or even nose-diving. This provides stability to the vehicle.

2. Control

Since the braking force is applied to both tires simultaneously, controlled braking occurs, which reduces the chance of the vehicle skidding.

3. Better braking performance

Since the CBS system involves both wheels in braking, there is an equalized braking power that improves the braking performance.

4. Simple braking operation

Since the driver doesn’t need to apply both brakes at once, the braking mechanism is simple in the CBS system.

As you can see from the above-mentioned points, the CBS system contributes to safe braking. It ensures the vehicle remains stable during braking, and there is no chance of any accidents.

Nowadays, electric motorbikes also come with the CBS braking system. Spiro’s electric motorbikes are no different, and their Commando range of e-motorbikes are equipped with the latest CBS braking system for improved braking performance and safety.

Potential Disadvantages of the CBS Braking System

Although CBS offers safety, it can be inconvenient to use in some situations. This leads to certain potential disadvantages of the CBS braking system that are discussed below:

1. Limited control

Since the CBS system distributes the brake force evenly between the two wheels, it can limit the rider’s control in situations where one might want to apply more brake force to the front or rear wheel for specific reasons.

2. Uneven braking

On uneven surfaces or even during emergency situations, the CBS system might not distribute the brake force evenly. This can cause instability for the rider.

3. Complexity

CBS braking is complex and require a variety of valves to manage the braking force. This can cause an increase in repair or maintenance costs.

Moreover, the CBS braking system might not be handy in situations where the driver panic brakes. The vehicle might not come to a complete halt and will need a larger stopping distance.

Exploring the CBS Brake Ratio

The braking ratio in vehicles is designed to achieve the most efficient and optimal braking performance. The brake ratio refers to the amount of force applied to each wheel. The brake ratio ensures stability and control in the vehicle and also minimizes skidding. Also, the brake ratio helps distribute the weight on vehicles and also ensures the tire is in contact with the road at all times.

For designing the ultimate brake ratio for vehicles, manufacturers have to take a lot of factors into consideration:

  • Suspension design
  • Tire Characteristics
  • Vehicle type and use
  • Driver Feedback
  • Regulatory requirements

Ultimately, the ideal brake force distribution ratio is a delicate balance that aims to provide safe and stable braking performance under a wide range of conditions.

In the CBS braking , the front and rear brakes act as a ratio combined. When the driver presses the rear brake, there will be a 60% braking effect on the back wheel, while pressing the front brake will give a 40% braking effect on the front wheel. 

Parting thoughts

Braking systems are an integral safety feature in vehicles. From safety and speed control to collision avoidance, braking systems contribute to road safety and prevent accidents.

The CBS system is an effective and efficient braking system designed specifically for two-wheelers. Most electric motorbikes of today come with the CBS braking system, as they are more affordable than their ABS counterparts.
