Combi Brake System in Bikes: Enhancing Safety and Control

The CBS braking system is a groundbreaking braking technology that enhances the safety and stability of two-wheelers. By combining the braking forces of both the front and rear wheels, CBS reduces braking distances, minimises skidding, and provides superior control over the bike. Designed primarily for motorcycles with engine capacities below 125cc, CBS has been a necessary feature for such vehicles in India since 2019, ensuring enhanced safety standards.  

What Does a Combi Brake System Mean?

Curious about “what is a combi brake system”? Here’s a quick overview:

• CBS is a mechanism that evenly distributes braking forces between the front and rear wheels.

• Unlike traditional systems, it activates both brakes simultaneously when either lever is pressed.

• This technology shortens stopping distances and improves bike stability, even on slippery terrains.

• It is especially effective in addressing improper brake usage by novice riders, offering better control and safety.

• By balancing individual brake components, CBS also reduces wear and tear, enhancing durability.

How Does a Combi Brake System Work?

The CBS braking system operates by accurately distributing braking forces. Here's how it works:

• Braking Force Distribution

When the rider depresses the rear or front brake lever, both brakes are automatically engaged.

• Brake Application

The CBS mechanism allocates braking force appropriately to the front and rear wheels, usually favouring the rear wheel to prevent the front wheel from locking.

• Better Stability

Engaging both wheels ensures skidding-free and controlled stoppage, enhancing overall safety.

What are the Advantages of the Combi Brake System?

After learning about what a combi brake system is, here are its key advantages:

Improved Safety

• Reduces braking distance significantly
• Prevents skidding, even on wet or uneven surfaces
• Maintains bike balance during emergency braking
• Provides stability, ensuring safer rides for less skilled riders

Ease of Use

• Enables riders to depend on a single lever for maximum braking efficiency
• Boosts confidence for the less skilled riders by simplifying braking
• Reduces mental stress during sudden stops by automatically distributing braking forces

Versatility

• Compatible with disc/drum and drum/drum brake configurations
• Effective on all road types, including highways, city streets, and rural roads
• Widely used in commuter bikes and scooters, making it easily accessible to a large audience

 Affordable Technology

• Less expensive compared to high-tech systems such as ABS
• Easy to maintain and repair, appealing to budget-conscious riders
• Lacks complex electronics, reducing long-term ownership costs

What are the Disadvantages of the Combi Brake System?

The combi brake system in bikes has some disadvantages, such as:

Not Suitable for High-Performance Bikes

• It is designed primarily for bikes with engine capacities below 125cc and may not be suitable for high-speed or high-power motorcycles.
• Cannot meet the high torque requirements of performance bikes, thus limiting its use.

Effect on Stunt Riding

• Limits flexibility for stunts and aggressive manoeuvres due to lack of independent control of the front and rear brakes.
• May also hinder the precision braking needed for intricate tricks.

Control Limitations for Experienced Riders

• Can be restrictive for riders preferring manual control in specific situations, such as off-road adventures.
• Non-adaptable for riders who frequently change braking patterns.

Reduced Performance in Extreme Conditions

• Falls short of ABS performance during heavy braking on extremely slippery roads.
• Less effective during hard braking over long or challenging conditions.

Compatibility Issues

• Not suitable for bike configurations requiring specific kinds of braking settings, such as dual front discs or advanced suspensions.

FAQs About the Combi Brake System

1. Is the Combi Brake System in bikes compulsory in India?

Yes, according to the Ministry of Road Transport and Highways, all two-wheelers sold after April 2019 with an engine capacity of 125cc or less must be equipped with CBS. This mandate enhances road safety, especially for entry-level bikes.

2. What is the difference between CBS and ABS?

• CBS distributes braking forces between the front and rear wheels, reducing skidding and enhancing stability. 

• ABS (Anti-lock Braking System) prevents wheel lock during critical braking, offering superior control. ABS is usually implemented in high-performance bikes, while CBS is designed for small two-wheelers.

3. Will CBS work on all braking systems?

Yes, CBS is compatible with both drum brakes and disc brakes. It is commonly used in drum-drum and disc-drum configurations for most bikes and scooters.

4. Does CBS affect maintenance costs?

The combi brake system in bikes is normally durable and needs the same regular maintenance as a typical braking system. Regular inspections ensure reliable performance without any extra costs.

5. Is bike insurance still required if my bike has CBS?

Yes, bike insurance is mandatory even if your vehicle is equipped with CBS. While CBS improves safety and reduces accident risks, it does not protect against theft, natural calamities, or third-party liabilities.

Conclusion

The combi brake system has revolutionised two-wheeler braking technology, addressing critical issues like skidding and improper braking. The CBS braking system enhances safety, boosts rider confidence, and is especially beneficial for new riders.

Although CBS is a valuable addition to two-wheeler safety standards, bike insurance is a non-negotiable and indispensable safety measure. Adequate insurance is both a legal obligation and a wise investment for the rider's personal safety and the bike’s financial security.
