Installation & safety
Installation Steps & Safety Instructions
Follow the fitment checks below before installing or riding with a NUTT hydraulic brake upgrade.
Confirm the correct configuration
Check the scooter model, production version, front or rear position, rotor side, mounting type and brake connector. Confirm whether a spacer, adapter cable or original washer is required.
Inspect the package before fitting
Make sure the caliper, lever, hose, brake pads and selected hardware match the purchased configuration. Do not install damaged parts or discard model-specific hardware before fitment is confirmed.
Remove the original brake safely
Secure the scooter before removing the original brake. Protect the rotor and hose area from contamination, and keep any original washers or model-specific parts for comparison.
Install the lever and caliper
Mount the lever and caliper using the correct hardware for the selected configuration. Keep the caliper aligned with the rotor and do not force parts into position.
Route the hose and check clearance
Route the hose away from sharp edges, moving parts and folding points. Check the gap around the caliper, rotor, fork, swingarm, tyre and other components before final tightening.
Test before normal riding
Check lever operation, rotor rubbing, bolt security and motor power cutoff. Complete a controlled low-speed test in a safe area before normal riding.
Hiley Series FAQ
Find answers about NUTT hydraulic brake fitment for Hiley EVO, Tiger, and TK-series electric scooters.
Is the 4-piston brake really necessary for high-power Hiley scooters?
Absolutely. For 60V high-performance models like the Hiley Tiger Supra, TK-RS, and TK-XS, a 4-piston system is a critical upgrade.
It provides the significantly stronger stopping power and precise modulation needed to safely control these heavy, high-speed machines compared to standard 2-piston designs.
How do I choose between 2-piston and 4-piston kits based on disc thickness?
The NUTT 2-piston model is optimized for standard 1.8 mm thick brake discs. In contrast, the 4-piston heavy-duty model is designed for 2.3 mm thick rotors.
Using a thinner disc with a 4-piston caliper may lead to a "softer" lever feel and weaker initial bite. For peak performance, we recommend pairing the 4-piston kit with 140x2.3mm rotors.
Do these brakes include cooling fin pads for steep hills?
Yes. Our premium kits come with integrated cooling fin brake pads capable of handling heat up to 450°C.
This is a major safety benefit for Hiley riders tackling steep descents or riding aggressively, as it prevents brake fade (loss of stopping power due to overheating) and ensures consistent performance.
Is the motor power-off sensor waterproof for all-weather riding?
Yes, the NUTT Hiley-series kits feature a fully waterproof power-off sensor. This ensures that the motor cutoff safety function remains 100% reliable even when encountering rain, puddles, or mud, protecting your scooter's electrical system from moisture ingress.
What is the default lever setup and can it be customized?
By default, the Left lever controls the Rear brake and the Right lever controls the Front brake. This matches the factory setup for Hiley EVO and Tiger models.
If you require a custom control direction (Moto-style), please contact nuttbraking@outlook.com before placing your order to ensure the hose lengths and bleed ports are configured correctly.
What photos should I send to confirm fitment for my Hiley model?
To ensure 100% compatibility with your specific production version, please send clear photos of:
- Front wheel: Showing the fork structure and caliper mount.
- Rear wheel: Showing the swingarm area and rotor side.
- Brake lever connector: Showing the power-off sensor plug (standard 2-pin waterproof).
