What is Disc Brakes?

Disc brakes are a type of braking system commonly used in vehicles, including cars, motorcycles, bicycles, e-scooters, and some other applications. They operate by using calipers to squeeze pairs of brake pads against a metal disc or rotor that is mounted on the wheel. This creates friction and slows down or stops the rotation of the wheel. Disc brakes may be actuated mechanically by cable or hydraulically.

"Mechanical"  vs. Hydraulic 

There are two main types of disc brakes: "mechanical" (cable-actuated) and hydraulic. Advantages and disadvantages are highly discussed by the users of each system. As advantages of cable-actuated disc brakes are argued as lower cost, lower maintenance, and lighter system weight, hydraulic disc brakes are said to offer more braking power and better control.


Mechanical Disc Brakes

Basic Component:

Mechanical disc brakes consist of a few key components that work together seamlessly to provide reliable braking. The main parts include the brake lever, cable, caliper, and rotor. Unlike traditional rim brakes, where friction is applied directly to the wheel's rim, disc brakes utilize a rotor attached to the wheel hub.


How They Work:

When the rider squeezes the brake lever, a cable is pulled, transmitting force to the caliper. The caliper houses brake pads that clamp onto the rotor, creating friction and slowing down the wheel. The mechanical system allows for precise control over the braking force, providing a responsive and predictable braking experience.



Pros and Cons:

Cable-actuated mechanical disc brakes offer simplicity and high reliability, making maintenance straightforward and troubleshooting easier compared to hydraulic disc brakes. This appeals to riders seeking a low-maintenance setup.


However, a significant drawback of mechanical brake systems is their tendency to experience dramatic fading on extended steep descents without hydraulic boosting. This inadequacy can compromise steering and scooter placement confidence when using maximum hand strength for braking. 


But off-road riders on a budget, or those keen on using their e-scooters for exploration riding and gravel travel can find great purpose in a cable-operated disc brake system.  Check Ausom Leopard E-Scooter with Mechanical Disc Brake.


Hydraulic Disc Brakes

Basic Components:

Hydraulic disc brakes comprise a hydraulic brake lever, hydraulic brake hose, caliper, and brake pads. 

How They Work:

Unlike their mechanical counterparts, hydraulic brakes rely on fluid (usually mineral oil or brake fluid) to transmit force from the brake lever to the caliper, resulting in the compression of brake pads against the rotor. 



Pros and Cons:


Precision in Motion

Hydraulic disc brakes are renowned for their precision and responsiveness, providing unparalleled stopping power. Ideal for swift deceleration on challenging terrains and navigating unexpected obstacles, they are a preferred choice among off-road enthusiasts tackling steep descents.


Lever feedback and bite-point precision

Hydraulic disc brakes enhance finger inputs, offering superior modulation and feedback compared to cable-actuated counterparts. When venturing on unfamiliar and technical trails, the hydraulic setup delivers unmatched lever feel and braking accuracy, allowing riders to tailor deceleration to the terrain and available grip.


Consistent Performance in Varied Conditions

Hydraulic disc brakes excel in adverse weather conditions. Unlike rim brakes prone to reduced effectiveness in wet or muddy environments, hydraulic brakes operate in a sealed system, minimizing the impact of external elements on performance.


Complexity and Maintenance

While hydraulic disc brakes offer superior performance and maintenance advantages, some riders may find the system more complex than mechanical alternatives. Specialized knowledge or professional assistance may be required for proper maintenance, including bleeding the hydraulic fluid. Despite this complexity, the maintenance frequency is typically once a season or year, instilling confidence in the reliability of the hydraulic braking system.



The impressive stopping power and fade resistance of hydraulic disc brakes come at a premium cost, averaging two to three times that of mechanical systems.



Hydraulic disc brakes represent a pinnacle in braking technology, providing riders with unmatched stopping power, precision, and reliability. As e-scooter enthusiasts seek to enhance their riding experience and tackle new challenges, the adoption of hydraulic disc brakes continues to grow. By understanding the intricacies of this advanced braking system, riders can make informed decisions about integrating hydraulic disc brakes into their riding, unlocking a new level of performance and control on the road or trail.   Check Ausom Gallop E-Scooter with Hydraulic Disc Brake.
