E-bike with hydraulic disc brake system seems cost more than e-bikes with other braking systems. But is the braking system really that good? Is it worth spending that much? Here we are to take you delve into the hydraulic braking system to figure it out.
What Are Hydraulic Disc Brakes?
Definition of hydraulic from WIKIPEDIA: is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
Components of Hydraulic Disc Brakes
Brake lever
The more force you apply to the brake lever, the stronger the braking power.
Hydraulic fluid
Hydraulic fluid is responsible for transmitting the force received by lever through brake lines to calipers.
Calipers
Clipers are responsible for pushing brake pads against rotors to generate friction and slow down.
Brake pads
Brake pads are responsible for friction generation to slow down your e-bike. The material it made is durable and high-temperature resistant to withstand consistant stopping power. But keep in mind that the brake pads need regular check to make sure you are safe every time you are riding.
Rotors
It is attached to wheel of your bike to generate friction while brake pads are pushed against rotor. Technicially, the bigger the rotor is, the greater stopping power.
How Hydraulic Disc Brakes Work?
The hydraulic disc brake works like the following sequence:
Brake pedal pressed; then force on pistons in the master cylinder exerted from a pushrod; brake fluid from reservoir flow into a pressure chamber through a compensating port; pressure increased of the entire braking system; fluid from hydraulic lines is forced through toward calipers; brake pads receive force from calipers to against spining rotor; friction between the pads and rotor generated to slow your e-bike.
Why Hydraulic Disc Brakes Are Considered the Best?
Stronger Power
Hydraulic delivers stronger power with less pressure on brake lever, making the system offers efficient stopping power. Perfect for adventurers who love complex terrain.
Consistant Performance
The brake system offers precise control without any hasstle like skidding or wheel locked up. Which ensures your bike could also perform well in all weather conditions, no matter it is wet or muddy.
Portable
Thanks to its more compact desigh as the hydraulic system applies sealed lines and fluid, making the system without hasstle of heavier mechanical cables and levers that a mechanical braking system has.
The e-bike S2 PRO is light weight with hydraulic brake system and dual batteries to extend your adventures.
Limitations of Hydraulic Braking System
More Expensive
Hydraulic braking system e-bikes costs more among bikes with other braking systems as it applied advance technologies.
Complicated maintenance
You many need to learn a bit professional knowledge to deal with fluid leak or remove air bubble from fluid.
Troubleshooting Common Issues
Air Bubbles in the Brake Lines
Symptoms
If the brake lever is not as reponsive as befor, there's a chance that there's air bubbles.
Solutions
Bleed fluid first, then refill with fresh brake fluid. The process helps to restore appropriate hydraulic pressure.
When you're bleeding fluid, better place it in a postion that bleeding point is at the hightest point compare to other parts of the bike. Once finish bleeding, let's have a test. If you feel firm while you press lever, good for you, no bubble left! Now it's time to refill fresh fluid. But if the lever gives you feeling of spongy, repeate the fluid bleed process.
Fluid Leakage
Symptoms
The most noticable symptom is oily spots, maybe on your bike or ground. Other symptoms would be much less efficient braking performance.
Solutions
Check the fluid reservior first, cause low fluid level indicates leak from somewhere in the system. If the leak is at tighten connection, just tighten connection; If the leak is from damaged hose, lever, seal or other parts, just replace it.
Conclusion
Hydraulic is considered the best e-bike braking system for its super efficient performance and a good assistance to challenge all kinds of terrains. But make sure what problems you'll have to deal with and do some research about how to solve these common problems if you get one. The e-bike becomes even more appeal as the S2 PRO is duall batteries powered for longer adventure!
