2. Safety Information
- Professional Installation Recommended: The installation of hydraulic brake systems requires specialized knowledge and tools. If you lack experience, it is strongly advised to have the brake set installed by a qualified bicycle mechanic to ensure correct and safe operation.
- Brake Fluid: This system uses mineral oil. Do not use DOT fluid, as it can damage the seals and components.
- Regular Checks: Before each ride, check brake lever feel, brake pad wear, and ensure there are no leaks in the hydraulic system.
- Rotor Compatibility: Ensure your bike's rotors are compatible with hydraulic disc brakes and are clean and free of oil or grease.
- Power Cut-off: The power cut-off feature is designed to disengage the motor when braking. Ensure this connection is properly made and tested before riding.

5. Setup and Installation
Important: Professional installation is highly recommended for safety and optimal performance.
5.1 Pre-Installation Checks
- Ensure all components listed in Section 3 are present and undamaged.
- Verify your bike's frame and fork have appropriate disc brake mounts.
- Confirm your rotors are clean and compatible.
5.2 Mounting Brake Levers
- Mount the brake levers on your handlebars. The front brake lever typically goes on the left side, and the rear brake lever on the right, but this can vary by region and rider preference.
- Secure the levers firmly but do not overtighten.

5.3 Mounting Brake Calipers
- Mount the brake calipers to your bike's frame and fork using appropriate adapters if necessary.
- Note: The brake clip (caliper) is designed to be mounted on the left side.
- Ensure the caliper is centered over the rotor and the pads are not rubbing. Adjust as needed.

5.4 Connecting Power Cut-off Wires
- Connect the 2-pin power cut-off plugs from the brake levers to your eBike or scooter's motor controller system. Refer to your eBike/scooter manual for specific connection points.
- Ensure connections are secure and protected from moisture.
5.5 Bleeding the System (if necessary)
The brake system may require bleeding after installation or if the lever feels spongy. This process removes air bubbles from the hydraulic lines.
- Locate the 'Oil change screw hole' on the caliper (see Figure 5.3).
- Use a mineral oil bleeding kit (sold separately) and follow the manufacturer's instructions for bleeding hydraulic disc brakes.
- Always use XOD-approved mineral oil.

5.6 Final Adjustments and Testing
- Adjust the reach of the brake levers to your preference.
- Spin the wheels to ensure no brake rub.
- Test the brakes at a slow speed in a safe area before riding. Ensure the power cut-off function activates correctly when the brake levers are engaged.
6. Operating Instructions
The XOD XD-F3000 hydraulic disc brakes provide powerful and consistent stopping performance. To operate:
- Braking: Gently squeeze the brake levers to apply braking force. The 4-piston design offers strong modulation and stopping power.
- Power Cut-off: When the brake levers are engaged, the integrated sensor sends a signal to your eBike/scooter controller, temporarily cutting power to the motor. This ensures safer braking, especially during emergency stops.
- Progressive Braking: Apply brakes progressively. Avoid sudden, hard braking, especially with the front brake, to prevent loss of control.
7. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your hydraulic disc brakes.
7.1 Daily/Pre-Ride Checks
- Check brake lever feel: It should be firm and consistent. A spongy feel indicates air in the system or low fluid.
- Inspect brake pads for wear. Replace if worn down to the wear indicator or if braking performance degrades.
- Ensure brake rotors are clean and free of contaminants.
- Check for any visible fluid leaks around the calipers, hoses, or levers.
7.2 Periodic Maintenance (Every 3-6 months or as needed)
- Brake Bleeding: If the brake lever feels spongy or inconsistent, the system may need to be bled to remove air. Use XOD-approved mineral oil and a proper bleeding kit.
- Brake Pad Replacement: Replace worn brake pads promptly. Ensure new pads are properly bedded in.
- Rotor Cleaning: Clean rotors with a dedicated disc brake cleaner to remove any residue that might affect braking performance.
- Hose Inspection: Check hydraulic hoses for any signs of damage, kinks, or wear. Replace if compromised.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Spongy brake lever | Air in the hydraulic system, low fluid level | Bleed the brake system, check for leaks and refill with mineral oil. |
| Poor braking performance | Worn brake pads, contaminated rotor/pads, air in system, improper bedding | Replace pads, clean rotor/pads, bleed system, re-bed pads. |
| Brake noise (squealing/grinding) | Contaminated pads/rotor, worn pads, loose caliper, misaligned caliper | Clean rotor/pads, replace pads, check caliper bolts, realign caliper. |
| Brake rub | Misaligned caliper, bent rotor, sticky pistons | Realign caliper, true or replace rotor, clean and lubricate pistons. |
| Power cut-off not working | Loose or incorrect wiring, faulty sensor | Check all 2-pin connections, consult eBike/scooter manual, contact support. |
9. User Tips
- Seek Professional Help: Given the critical safety role of brakes, if you are unsure about any installation or maintenance step, always consult a professional bicycle mechanic. Incorrect installation can lead to serious injury.
- Bedding-in New Pads: After installing new brake pads or rotors, perform a 'bedding-in' procedure. This involves several moderate stops from a medium speed to allow the pads to conform to the rotor surface, improving braking power and reducing noise.
- Cleanliness is Key: Keep your brake components, especially rotors and pads, free from oil, grease, and dirt. Even a small amount of contamination can severely reduce braking performance.
10. Warranty and Support
For warranty claims, technical support, or replacement parts, please contact the seller or manufacturer directly. Keep your proof of purchase for any warranty-related inquiries. Ensure you provide the model number (XD-F3000) and a detailed description of the issue when seeking support.
