Setup and Installation
Proper installation is crucial for the safe and effective operation of your hydraulic disc brakes. The hoses are pre-filled with mineral oil, so bleeding is generally not required immediately after installation.
1. Determine Brake Type Compatibility
Before installation, identify the correct brake type (L-L, L-R, R-R) needed for your scooter. This depends on the brake rotor position on your front and rear wheels.

Video Description: This video explains how to identify the correct brake configuration (left or right) for your electric scooter based on the brake rotor's mounting position.
2. Brake Lever Installation
The brake lever can be installed without removing the grip due to its split design. Remove the screw on the brake handle, position it on the handlebar, and then tighten the screw to secure it.

3. Hose Connection
The LD-210S brakes feature an outer 360° rotating heat dissipation universal joint and a hose split design, making installation easier. Carefully connect the brake hoses to the levers and calipers. Ensure a clearance of 0.5 to 0.8 millimeters when fitting the copper bushing, then tighten the screw with 80 kg torque and put on a protective rubber sleeve.

4. Caliper Installation
The hole spacing on the brake kit meets industry standard dimensions (74 mm / 2.91 in). Use the provided M6*18mm screws to connect the adapter and the frame, ensuring the parts are coordinated. You may add gaskets between parts if needed. Tighten the screws with a 5mm wrench.

Video Description: This video details the process of installing the brake caliper onto the scooter frame and aligning it with the disc.
5. Power-Off Sensor Connection
The electric induction control system features a detachable power-off sensor. This sensor cuts off motor power output when braking, ensuring safe riding. The cable length is 300mm (11.8in) and uses a 2-pin waterproof connector. Ensure the wiring port matches your scooter.
Operating Instructions
The DYISLAND LD-210S hydraulic disc brakes provide responsive and controlled stopping power for your electric scooter.
Brake Lever Adjustment
The brake handle features a screw adjustment function. This allows you to customize the travel distance of the brake lever to suit your personal preference, providing a comfortable and flexible braking operation for optimal braking feel.

Maintenance
Regular maintenance ensures the longevity and performance of your hydraulic disc brakes.
Brake Pad Adjustment
When brake pads wear out, rotate the adjusting knob on the caliper to adjust the distance between the brake pads and the brake disc. This helps maintain optimal brake feel and performance.

Brake Bleeding
While your brakes come pre-filled, over time, air may enter the hydraulic system, leading to a spongy brake feel. Bleeding the brakes removes air and restores firm lever feel.

Troubleshooting
If you encounter issues with your DYISLAND LD-210S Hydraulic Disc Brakes, refer to the following common problems and solutions:
- Spongy Brake Lever: This usually indicates air in the hydraulic system. Refer to the "Bleeding Tutorial Video" in the Maintenance section to bleed your brakes.
- Brake Rubbing/Friction Sound: This can occur if the caliper is not properly aligned with the brake disc. Re-adjust the brake position as shown in the installation videos in the Setup section. Ensure all mounting screws are tightened correctly.
- Weak Braking Performance: Check for worn brake pads (adjust or replace if necessary) or air in the system (bleed brakes). Ensure the brake lever travel distance is adjusted to your preference.
- Power-Off Sensor Malfunction: Verify that the 2-pin waterproof connector is securely attached and that the wiring port matches your scooter's specifications.
