Brakes are an important part of any electric bike. Disc brakes have taken over a market once dominated by rim brakes. With disc brakes, you have two systems to choose from - mechanical and hydraulic. In this article, we'll explore the similarities and differences between mechanical and hydraulic disc brakes, and help you choose between one style and the other.
Mechanical brakes use cables or linkages to transmit the force from the brake pedal to the brake mechanism at each wheel. The force is applied to the brake disc through a series of levers, rods, and pivots.
Hydraulic brakes, on the other hand, use a fluid-filled system to transmit the force from the brake pedal to the brakes at each wheel. When the brake pedal is pressed, it pushes a piston in the master cylinder, which pressurizes the brake fluid in the brake lines. This pressure is then transmitted to the brake mechanisms at each wheel, causing the brakes to engage.
What are the advantages and disadvantages of mechanical disc brakes?
Advantages of mechanical disc brakes:
1.Simpler design and installation process
2.Lower cost compared to hydraulic disc brakes
3.Easier maintenance and repair
4.Suitable for entry-level or recreational cycling
5.More compatible with existing rim brake levers
Disadvantages of mechanical disc brakes:
1.Lower stopping power compared to hydraulic disc brakes
2.Greater susceptibility to wear and tear, leading to reduced performance over time
3.Tendency to produce noise when braking
4.Increased hand fatigue due to the need for greater force to apply the brakes
5.Limited adjustability and precision compared to hydraulic disc brakes.

What is the difference?
The main difference between mechanical and hydraulic brakes on ebikes is the way they operate. Mechanical brakes rely on a cable that connects the brake lever to the brake caliper, while hydraulic brakes use a sealed fluid system to transfer force from the brake lever to the caliper. Here are some other differences between the two types of brakes:
- Stopping power
Hydraulic brakes generally offer more stopping power than mechanical brakes. This is especially important for ebikes, which can be heavier and travel at higher speeds.
- Modulation
Hydraulic brakes offer more precise modulation of the braking force, allowing riders to apply the brakes more smoothly and with greater control. Mechanical brakes can feel more on/off, making it harder to apply the right amount of braking force in different situations.
- Maintenance
Hydraulic brakes require more maintenance than mechanical brakes. The hydraulic fluid needs to be changed periodically, and the system needs to be bled to remove any air bubbles. Mechanical brakes are generally easier to maintain and repair.
- Cost
Hydraulic brakes are generally more expensive than mechanical brakes, due to the additional components and materials required.
Conclusion
Overall, hydraulic brakes offer better performance and control than mechanical brakes, especially for high-performance e-bikes. However, they require more maintenance and can be more expensive. Mechanical brakes are a good option for entry-level or recreational e-bikes, where cost and simplicity are more important than performance.
