FAQ

XOD hydraulic brake products include D Series, E Series, F Series, GT Series, H Series, T Series, JZ Series and MS Series. Each series is designed for different vehicle types, including e-bikes, electric scooters, electric motorcycles, cargo trikes, mountain bikes and other light electric vehicles.

The correct XOD brake series depends on your vehicle type, braking requirements and installation structure. The H Series is commonly used for electric scooters and e-bikes. The D Series is designed for high-frequency use vehicles such as delivery bikes and rental vehicles. The E Series supports e-bikes, fat bikes and commuting bikes. The F Series and GT Series are suitable for high-power e-bikes, electric motorcycles and performance applications. The T Series is designed for cargo trikes, electric tricycles and CBS linked braking systems.

XOD brake systems are designed for a wide range of light electric vehicles, but correct fitment must be checked before ordering. Compatibility depends on vehicle type, brake disc side, caliper mounting position, front fork or rear swingarm structure, rotor size, hose routing and brake lever connector.

For uncertain setups, please send XOD clear photos before ordering.

XOD H800 and H880 are hydraulic brake versions designed for different mounting directions and scooter brake layouts. H800/H880 selection should not be based only on left-side or right-side appearance.

Correct selection depends on wheel position, brake disc side, caliper mounting position, suspension structure, rotor size, hose routing and brake lever connector.

For common KuKirin reference examples, KuKirin G4 uses front H880 and rear H800, KuKirin G2 Max uses front H800 and rear H880, and KuKirin G2 Master 2025 uses H880 for both front and rear wheels.

Customers should still confirm the actual scooter layout before ordering, especially if the scooter version, brake disc side or caliper structure looks different from the reference photos.

Please send clear photos of your scooter model, front wheel brake disc side, rear wheel brake disc side, caliper mounting position, front fork or rear swingarm structure, brake lever connector and hose routing. These photos help XOD confirm whether H800, H880 or another hydraulic brake setup is suitable before you order.

For daily urban commuting and regular e-bike or scooter use, 2-piston hydraulic brakes are reliable and efficient. For high-power e-bikes, electric motorcycles, heavy fat bikes or off-road riding, 4-piston hydraulic brakes such as selected GT Series and F Series options can provide stronger clamping force and better heat management.

XOD replacement brake pads should be selected according to your brake model, riding conditions and braking requirements.

• Resin or ceramic pads: quieter braking feel for city riding and lighter daily use.
• Multi-metal or copper-based pads: balanced braking power, durability and heat control for general riding.
• Full-metal or sintered pads: higher wear resistance for heavy-duty riding, delivery use and demanding off-road conditions.

Always confirm pad shape and compatibility before ordering.

Many XOD electric scooter hydraulic brake kits include brake levers with motor power-off sensor support. When compatible with your scooter, the sensor helps cut motor power when the brake lever is pressed. Please check your original brake lever connector before ordering.

XOD hydraulic brake systems use mineral oil for stable braking feel and easier maintenance. Mineral oil is less corrosive than DOT fluid and is more suitable for many DIY maintenance situations. Always use the correct brake fluid type recommended for your brake system.

XOD hydraulic brake systems are designed for practical maintenance. Many kits arrive pre-bled and ready to install. Routine brake pad replacement and basic checks are straightforward for experienced users, but hose shortening, disconnection or hydraulic adjustment may require bleeding.

Beginners should ask a professional mechanic or installer for help.

For the best braking performance, rotor condition and size should be checked when upgrading calipers. A compatible, flat and properly sized rotor helps reduce vibration, heat fade and inconsistent braking feel. XOD also provides premium universal brake rotors for compatible upgrade and replacement applications.

CBS means Combined Braking System. The core idea of CBS is to coordinate the front and rear brakes to provide a more stable braking experience. When a vehicle needs emergency braking, the front and rear brakes can work together, helping increase braking friction and support faster, more stable stopping.

CBS linked braking is especially relevant for electric tricycles, cargo trikes, utility vehicles and other light electric vehicles that require balanced braking control.
