- ✔ Hydraulic brake response with less cable stretch than mechanical systems.
- ✔ XOD H880 front and rear setup for the KuKirin G2 Master 2025 version shown here.
- ✔ ABS power-off support when the brake lever connector is correctly connected.

Important: This result applies to the KuKirin G2 Master 2025 version shown in this article. Do not assume every G2 Master model year uses the same brake layout.
Brake Lever Connector and ABS Power-Off Sensor Check
Before installation, check the original brake lever connector and the XOD H880 brake lever connector. For the KuKirin G2 Master 2025 setup shown here, the XOD H880 brake lever supports the ABS power-off / motor cut-off function, and the brake lever connector is fully compatible.
Connector Tip: To connect the ABS power-off sensor correctly the first time, align the black arrows on both connector ends before pushing the plugs together. Do not force the connector if the arrows are not aligned.

Installation Notes from This G2 Master 2025 Build
This article does not replace the complete XOD user manual. It highlights the main fitment and installation points from this KuKirin G2 Master 2025 H880 build.
1. Front and Rear Brake Position
In this example, the front brake disc is on the right side and the rear brake disc is on the left side. Both positions use XOD H880. Always compare your own scooter with the photos before ordering.
2. Hose Routing Note
To route the brake hose on the KuKirin G2 Master 2025, remove the deck or footboard screws using a low-torque electric screwdriver or the tools supplied in the KuKirin toolkit. Then follow the original brake cable path and replace the mechanical brake cable with the XOD hydraulic hose. Before closing the deck, make sure the hose is not twisted, pinched, pulled too tight, or rubbing against the tire, rotor, folding mechanism, or sharp frame edges.
3. Caliper Alignment
After mounting the XOD H880 caliper, keep the caliper mounting bolts slightly loose first. Before tightening the bolts fully, use one hand to squeeze and hold the matching brake lever. This lets the rotor sit naturally in the center of the caliper between the brake pads. While holding the brake lever, tighten the caliper mounting bolts gradually. This simple trick helps center the caliper in one step and reduces the chance of rotor rubbing.
Pro Tip: Hold the brake lever first, then tighten the caliper bolts. This helps the brake disc stay centered inside the caliper during tightening.
4. Final Safety Check
- ✔ The brake lever should feel firm, not soft or spongy.
- ✔ The rotor should not rub constantly against the brake pads.
- ✔ The hydraulic hose should not be twisted, pinched, or pulled too tight.
- ✔ The ABS power-off sensor should cut motor power when the brake lever is pressed.
- ✔ Test the scooter at low speed before normal riding.
